Cryptanalysis of an identity based broadcast encryption scheme without random oracles
چکیده انگلیسی

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.

Research highlights
► We analyze a recent identity-based broadcast encryption scheme.
► We present a chosen-plaintext attack against this scheme.
► Our attack indicate that this scheme is even not chosen-plaintext secure.
