> 中文摘要: 提出并分析了一种确定的、可并行的消息认证码--DPMAC(deterministic parallelizable message authentication code).它基于分组长度为128-bit的分组密码来构造.使用一个密钥,可以处理任意长度的消息.在底层分组密码是伪随机置换的假设下,使用Game-Playing技术量化了攻击者成功伪造的概率,从而证明了其安全性.
Abstract:This paper defines and analyzes a fully deterministic parallelizable block-cipher mode of operation for message authentication — DPMAC (deterministic parallelizable message authentication code). DPMAC is constructed based on a 128-bit block cipher, works for strings of any bit length, and employs a single block-cipher key. Its security is proved, using the Game-Playing technique to quantify an adversary’s forgery probability in terms of the quality of the block cipher as a pseudo-random permutation.
