Abstract

Identity based broadcast encryption allows a centralized transmitter to send encrypted messages to a set of identities S, so that only the users with identity in S can decrypt these ciphertexts using their respective private key. Recently [Information Processing Letters 109 (2009)], an identity-based broadcast encryption scheme was proposed (Ren and Gu, 2009) [1], and it was claimed to be fully chosen-ciphertext secure without random oracles. However, by giving a concrete attack, we indicate that this scheme is even not chosen-plaintext secure.

Cryptanalysis of an (hierarchical) identity based parallel key-insulated encryption scheme

Abstract: Recently, Ren and Gu (2010) proposed an identity-based parallel key-insulated encryption (IBPKIE) scheme, and further extended their IBPKIE scheme to a hierarchical identity-based parallel key-insulated encryption (HIBPKIE) scheme. They claimed ...
Secure public-key encryption scheme without random oracles

Since the first practical and secure public-key encryption scheme without random oracles proposed by Cramer and Shoup in 1998, Cramer-Shoup's scheme and its variants remained the only practical and secure public-key encryption scheme without random ...
Cryptanalysis on a Secret-Sharing Based Conditional Proxy Re-Encryption Scheme

Condition proxy re-encryption is a promising security primitive for pervasive data sharing in such settings as cloud-based social networks and collaborations. However, it is challenging to create a secure condition proxy re-encryption scheme that is ...
