数字签名:靠加密解密算法进行支撑 单向散列算法 MD5,SHA 非对称密钥算法:RSA 数字签名算法:DSA(Digital Signture Algorithm) 数字签名标准:DSS(DigitalSinature Standard) 使用私钥对摘要进行加密,即为数字签名! 下图描述了数字签名的大概流程,具体流程比这个稍微复杂一些。 数字签名算法---加密学习笔记(五) 算法:RS...
To reduce the communication payload overhead introduced by the algorithm, improvements are made to the traditional message digest 5 (MD5) encryption algorithm, reducing the length of the encrypted results. In order to reduce the authentication time overhead and re...
lab 4 EIGRP MD5 Authentication EIGRP MD5 Authentication MD5 authentication is a cryptographic authentication. A key (password) and key ID are configured on each router. The router uses an algorithm based on therouting protocol packet, the key, and the key IDto generate a message digest (also ...
The client and server use nonces to authenticate themselves to each other using the MD5 authentication algorithm. Nonce refers to a 'number used once'. It is often a random or pseudo-random number issued in an authentication protocol to ensure that old communications cannot be reused in 'repeat...
When using the CRAM-MD5 mechanism, the LDAP server sends some data to the LDAP client. The client responds by encrypting the data with its password by using the MD5 algorithm. The LDAP server then uses the client's stored password to determine whether the client used the right password. ...
Because the algorithm for calculating CHAP responses is well known, it is very important that passwords be carefully chosen and sufficiently long. CHAP passwords that are common words or names are vulnerable to dictionary attacks if they can be discovered by comparing responses to the CHAP challenge...

The timestamp is hashed with the username and the shared secret key through the MD5 algorithm. There are still a few problems with this, the first of which is that all values are known in advance except the shared secret key. Because of this, there is nothing to provide protection against...
