Bar mitzvah attack : ウィキペディア英語版 | Bar mitzvah attack The Bar mitzvah attack is an attack on the SSL/TLS protocols that exploits the use of the RC4 cipher with weak keys for that cipher. While this affects only the first hundred or so bytes of only the very small fraction of connections that happen to use weak keys, it allows significant compromise of user security, for example by allowing the interception of password information〔 which could then be used for long-term exploitation. The attack uses a vulnerability in RC4 described as the ''invariance weakness'' by Fluhrer et. al. in their 2001 paper on RC4 weaknesses.〔〔Fluhrer, S., Mantin, I., and A. Shamir, "(Weaknesses in the Key Scheduling Algorithm of RC4 )", Selected Areas of Cryptography: SAC 2001, Lecture Notes in Computer Science Vol. 2259, pp 1-24, 2001.〕 == References ==
