It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application, please refer to fig. 1, which includes a terminal device, a chip external server, and a chip internal server. The terminal equipment may include an ISE chip. The terminal equipment can be communicated with the external server of the chip, and the external server of the chip can be communicated with the internal server of the chip. The off-chip server and the on-chip server may be servers of an ISE chip vendor.
An ISE application developer, or an ISE system developer, may perform program development on an ISE chip in the terminal device. When the program is developed, the generated ISE log is a log ciphertext. When the log ciphertext needs to be read, the terminal device can send the account information and the log ciphertext to the external server of the chip. After receiving the account information and the log ciphertext, the external server of the chip may forward the account information and the log ciphertext to the internal server of the chip. The chip internal server can obtain the log plaintext corresponding to the log ciphertext according to the account information and send the log plaintext to the chip external server. The chip external server may send the log plaintext to the terminal device so that the terminal device obtains the log plaintext, or the chip external server may save the log plaintext for a worker to view. And the staff can analyze the fault information of the program in the terminal equipment according to the log plaintext.
In the related art, in order to prevent external personnel from attacking the ISE chip by analyzing the ISE log, the ISE log generated in the process of developing a program in the ISE chip is a log ciphertext, and the ISE log cannot be directly decrypted in the ISE chip, so that the ISE log cannot be used.
In the embodiment of the application, the server in the chip can acquire the account information and the log ciphertext sent by the terminal device, and acquire the log plaintext corresponding to the log ciphertext according to the account information. The chip internal server can send the log plaintext to the chip external server so that the terminal device can obtain the log plaintext. Because the log plaintext corresponding to the log ciphertext can be obtained through the server in the chip, the ISE log is prevented from being directly decrypted in the ISE chip, and therefore the ISE log can be used.
The technical means shown in the present application will be described in detail below with reference to specific examples. It should be noted that the following embodiments may exist alone or in combination with each other, and description of the same or similar contents is not repeated in different embodiments.
Fig. 2 is a schematic flowchart of a log processing method according to an embodiment of the present application. Referring to fig. 2, the method may include:
s201, account information of the terminal device is obtained.
The execution main body of the embodiment of the application may be an internal server of a chip, or may be a log processing device disposed in the internal server of the chip. The log processing means may be implemented by software, or may be implemented by a combination of software and hardware. The log processing means may be a processor in an on-chip server. For ease of understanding, the execution subject is described as an example of an on-chip server in the following.
The terminal device may be an electronic device mounted with an ISE chip. For example, the terminal device may be a computer.
Programs can be developed in the terminal device based on the ISE chip. For example, an ISE application developer may develop an application in a terminal device based on an ISE chip; an ISE system developer can develop a development system based on an ISE chip in a terminal device.
The terminal device may have a corresponding chip external server, and the terminal device may send the account information to the corresponding chip external server. After receiving the account information, the chip external server may forward the account information to the chip internal server, so that the chip internal server obtains the account information of the terminal device.
It should be noted that, for one ISE application developer, the account information set in the terminal device may be the same, and all account information is the account information registered by the ISE application developer in the chip external server of the ISE chip manufacturer.
S202, obtaining a log ciphertext of the terminal device.
The log ciphertext is an ISE log generated by a program developed in the terminal device, and records all behaviors of the terminal device.
The terminal device may send the log ciphertext to a server external to the chip. After receiving the log ciphertext, the external server may forward the log ciphertext to the internal server, so that the internal server may obtain the log ciphertext of the terminal device.
And S203, acquiring a log plaintext corresponding to the log ciphertext according to the account information.
In an optional embodiment, the server inside the chip may determine, according to the account information, a key name corresponding to the account information; and acquiring a log plaintext according to the key name.
For example, if the chip internal server obtains the account-a and the log ciphertext-1 sent by the terminal device, the chip internal server may determine, according to the account-a, that the corresponding key name is the key name-1, and obtain, according to the key name-1, the log plaintext corresponding to the log ciphertext-1.
The log plaintext may be obtained from the key name by: sending the key name and the log ciphertext to an encryptor; and receiving the log plaintext sent by the encryption machine. The log plaintext is obtained by decrypting the log ciphertext by the encryption machine.
For example, if the chip internal server determines that the corresponding key name is the key name-1 according to the account-a, the chip internal server may send the key name-1 and the log ciphertext-1 to the encryptor, so that the encryptor may decrypt the log ciphertext-1 according to the key name-1 to obtain the log plaintext-1. The chip internal server can receive the log plaintext-1 sent by the encryption machine.
And S204, sending a log plaintext to a server outside the chip.
The chip internal server can send the log plaintext to the chip external server, so that the log plaintext can be stored in the chip external server. The staff can view the log plaintext on a server external to the chip.
Optionally, the chip external server may send the log plaintext to the terminal device, so that the terminal device obtains the log plaintext. The log plaintext may be used to determine fault information for a program in the terminal device.
In the embodiment of the application, the server inside the chip can acquire the account information and the log ciphertext of the terminal device through the server outside the chip, and determine the key name according to the account information. The server in the chip can send the key name and the log ciphertext to the encryption machine, so that the encryption machine can decrypt the log ciphertext according to the key name to obtain the corresponding log plaintext. The server in the chip can receive the log plaintext sent by the encryption machine and send the log plaintext to the server outside the chip, so that the terminal equipment can obtain the log plaintext. The server in the chip acquires the log plaintext corresponding to the log ciphertext and sends the log plaintext to the server outside the chip, so that the terminal equipment can acquire the log plaintext, and the ISE log is prevented from being directly decrypted in the ISE chip, so that the ISE log can be used.
Next, based on the embodiment shown in fig. 2, the log processing method will be further described in detail with reference to fig. 3. Fig. 3 is a schematic flowchart of another log processing method according to an embodiment of the present application. Referring to fig. 3, the method may include:
s301, receiving a registration request sent by the terminal equipment.
The registration request is used for the terminal equipment to register an account in the server in the chip. The registration request may include account information and device information of the terminal device. The device information of the terminal device may include an address of the terminal device, a company to which the terminal device belongs, and the like. For example, the registration request may include account number-A and "A technologies, Inc.
The terminal device may send a registration request to the off-chip server. After receiving the registration request, the off-chip server may forward the registration request to the on-chip server, so that the on-chip server may obtain the registration request of the terminal device.
And S302, sending a registration response corresponding to the registration request to the terminal equipment.
The registration response may be used to indicate registration success or failure. For example, the registration response may be "Account-A registration successful".
After receiving the registration request, the on-chip server may generate a registration response according to the registration request, and send the registration response to the off-chip server. After receiving the registration response, the external server may send the registration response to the terminal device, so that the terminal device obtains the registration response and knows whether the registration is successful.
For example, if the on-chip server generates a registration response according to the registration request, that is, the account-a registration is successful, the on-chip server may send the registration response to the on-chip server, and the on-chip server may send the registration response to the terminal device. After the terminal device obtains the registration response, the terminal device can know that the registration is successful according to the registration response.
And S303, acquiring account information of the terminal equipment.
It should be noted that the execution process of S303 may refer to S201, and is not described herein again.
S304, obtaining the log ciphertext of the terminal equipment.
It should be noted that the execution process of S304 may refer to S202, and is not described herein again.
S305, determining a key name corresponding to the account information according to the account information.
Optionally, the server inside the chip may determine, according to the account information, a key name corresponding to the account information in the account-key correspondence table. The account-key correspondence table may be stored in the chip internal server by a worker in advance.
Next, the account-key correspondence table will be described with reference to fig. 4.
Fig. 4 is a schematic diagram of an account-key correspondence table provided in the embodiment of the present application. As shown in fig. 4, the account-key correspondence table may include a plurality of accounts and a plurality of key names. The account number and the key name correspond to each other one by one.
For example, account-key correspondence tables may include account-A, account-B, account-C, … …, account-N, and key name-1, key name-2, key name-3, … …, key name-N. The key name corresponding to the account-a is the key name-1, the key name corresponding to the account-B is the key name-2, the key name corresponding to the account-C is the key names-3 and … …, and the key name corresponding to the account-N is the key name-N.
For example, the on-chip server may determine, according to the account-a, a key name corresponding to the account-a in the account-key correspondence table as the key name-1.
S306, sending a decryption request to the encryption device.
In order to protect information security, the on-chip server and the encryptor may be located in the same local area network. For example, the local area network may be an intranet of a chip vendor.
The server in the chip can send a decryption request to the encryptor in the local area network in two ways:
mode 1: may be by way of a wired network. For example, a data line may be used to connect the hardware interface of the on-chip server and the encryptor so that the on-chip server may send a decryption request to the encryptor in a local area network.
Mode 2: may be by way of a wireless network. The Wireless network may be Bluetooth (BT), Wireless communication technology (Wi-Fi), etc. The on-chip server may send a decryption request to the encryptor in the local area network in a wireless manner.
The decryption request may include a key name and a log ciphertext. For example, the decryption request may include a key name-1 and a log ciphertext-1.
The server in the chip can send a decryption request to the encryptor, so that the encryptor can decrypt the log ciphertext according to the decryption request.
Next, the encryption device will be described with reference to fig. 5.
Fig. 5 is a schematic diagram of an encryption apparatus according to an embodiment of the present application. Referring to fig. 5, a plurality of keys may be stored in the encryption engine, each key having a corresponding key name. For example, key name-1, key name-2, key name-3, … …, key name-n, and key-1, key-2, key-3, … …, key-n may be included in the encryptor. Wherein key name-1 is used to determine key-1, key name-2 is used to determine key-2, key name-3 is used to determine key-3, … …, and key name-n is used to determine key-n. The key is a parameter, and is a parameter required to be input in an algorithm for converting a log ciphertext into a log plaintext or converting the log plaintext into the log ciphertext. For example, the key may be "23059802826269955". The encryption machine can determine a key according to the key name, and then decrypt the log ciphertext through an algorithm according to the key.
For example, the server inside the chip may send a decryption request to the encryptor, where the decryption request includes the key name-1 and the log ciphertext-1, and the encryptor may determine the key-1 according to the key name-1 and decrypt the log ciphertext-1 through an algorithm according to the key-1.
And S307, receiving a decryption response corresponding to the decryption request sent by the encryptor.
The server inside the chip can receive a decryption response corresponding to the decryption request sent by the encryption in a wired or wireless mode in the local area network. The decryption response may include a log plaintext, which is obtained by the encryption machine decrypting the log ciphertext according to the key.
For example, if the encryption machine obtains that the decryption request includes the key name-1 and the log ciphertext-1, the encryption machine may determine the key-1 according to the key name-1, and further decrypt the log ciphertext-1 through an algorithm according to the key-1 to obtain the log plaintext-1. The encryptor may send a decryption response to the on-chip server in the local area network so that the on-chip server may receive the decryption response, which may include "decryption complete" and log plaintext-1.
And S308, sending the log plaintext to a server outside the chip.
It should be noted that the execution process of S308 may refer to S204, and is not described herein again.
In the embodiment of the application, the chip internal server may obtain the registration request of the terminal device through the chip external server, and send the registration response to the terminal device. After the registration is successful, if the log ciphertext needs to be decrypted, the server inside the chip can acquire the account information and the log ciphertext of the terminal device through the server outside the chip, and determine the key name according to the account information.
