Split Knowledge Generation of RSA Parameters

Public-key cryptography can be claimed as the greatest and an excellent revolution in the field of cryptography. A public-key cryptosystem is used for both confidentiality and authentication. One such public-key cryptosystem is the RSA cryptosystem. In ...

Recently Victor Shoup noted that there is a gap in the widely believed security result of OAEP against adaptive chosen-ciphertext attacks. Moreover, he showed that, presumably, OAEP cannot be proven secure from the one-wayness of the underlying trapdoor ...

A digital multisignature is a digital signature of a message generated by multiple signers with knowledge of multiple private keys. In this paper, an efficient RSA multisignature scheme based on Shamir's identity-based signature (IBS) scheme is ...
