文中提出了一种新的基于单向哈希函数的一次性口令认证方案。
A new Hash function based on scheme of one time password system is raised in this paper.
为了克服其方案密钥量大的缺陷，通过去掉单向哈希函数，给出1个改进方案。
To overcome the weakness of too many keys, we present an improvement of their signature scheme by getting rid of the one-way Hash function.
消息摘要是安全的单向哈希函数，它可以接受任意大小的输入数据，并输出固定长度的二进制哈希值。
Message digests are secure one-way hash functions that take arbitrary-sized data and output a fixed-length binary hash value.
在简化pki系统的研究中，本文首先介绍基于身份的加密算法，然后结合单向哈希链，提出一种基于IBE的改进PKI系统。
In the research of simplifying PKI system, this paper proposes an improved PKI system based on the combine of the IBE and the one-way hash chain.
UsernameToken规范允许使用单向安全哈希来保护摘要形式的密码，但ApplicationServerv6中没有提供该功能。
The UsernameToken specification allows for the use of a one-way secure hash to protect the password called a digest, but this functionality is not provided in Application Server V6.
消息摘要是一个安全的、单向的哈希函数，把任意长度的数据转化成固定长度的校验和/哈希码。
Message Digests are secure, one-way hash functions that convert arbitrary length data into fixed-length check sum / hash code.
哈希值对于经过哈希处理的消息来说是唯一的，而且由于哈希是单向的，因此哈希值不会暴露消息内容。
The values of the hash are unique for the hashed message, and the hash values will not expose the message since the hash is one way only.
如果你加密的字段，你只需要验证(不回忆)，然后简单哈希sha或单向加密与DES或使用盐的IDEA以防止彩虹表实际显露它们。
If you are encrypting fields that you only need to verify (not recall), then simple hash with SHA or one-way encrypt with DES, or IDEA using a salt to prevent a rainbow table to actually reveal them.
