摘要 最优非对称加密填充(OAEP)因其可证安全和实用有效而被人们广泛接受和认可。文中介绍了OAEP加密变换及已有的几种OAEP改进方案,并对这些方案的时间效率、空间效率和安全性能等分别进行了分析和比较。分析结果显示,OAEP+、SAEP+、PSS-E和OAEP++等方案在提高安全性的同时延续了最初OAEP变换的思想,3轮OAEP方案则实现了目前为止对OAEP的最优化改进。 This paper decribes the OAEP（Optimal Asymmetric Encryption Protocol） transformation, including several modified schemes. OAEP is widely accepted because of its provable security and practicability. This paper gives a detail analysis on these schemes from the viewpoint of time efficiency, space complexity and security.
