一种新的一阶段加密认证模式
A New One-Pass Authenticated Encryption Model
摘要
Abstract
In many practical applications of information security,an authenticated-encryption scheme is often constructed by appropriately combining an encryption scheme and a message authentication code. Using this scheme, the same message must be deal with in two-pass,not only using two keys,but also having low efficiency. Based on CBC mode, we propose a new one-pass authenticated encryption mode OXCBC, which provides privacy and authenticity simultaneously. OXCBC uses only one key and a nonce and is more efficient than other one-pass authenticated encryption schemes. We prove OXCBC secure,quantifying the adversary' s ability to violate the mode's authenticity in terms of the quality of its block cipher as a strong PRP.关键词
