Firstly, this paper puts forward an improved authentication and key distribution scheme for internet environment, in which we adhibit multilevel authentication center, encryption technology of DES, RSA and one-way function to actualize the safety of communication among the different user on network and reduces the workload of the authentication institution; at the same time, this scheme can also assure the security of network. Besides, it use the temporary symbol and the responds" sign of both-side correspondent to replace time stamp and applies them to internet communication to countercheck "rebroadcast attack and accordingly resolves the problem that it needs synchronization for network clock.

本文在首先提出一种改进的Internet网络环境下的认证及密钥分配方案，该方案考虑采用了多级认证中心，DES、RSA和单向函数加密机制，实现了网络上不同用户间的安全通信，降低了网上认证机构的工作量，同时也能够保证网络的安全性；并用通信双方的临时标志和响应者标识来代替时间戳应用于Internet通信中以防止"重播"攻击，从而解决了以往需要网络时钟同步这一难题。

The conformation of disulfide bonds, secondary structures, crystallinity and α-crystallinity of the cashmere fiber are changed after the cashmere yarn is steamed above 120℃ in relaxed and stretched state or crabbed at 98 ℃, 130℃ for different time, which is firstly found out. These structure changes of the treated cashmere fiber are related to temperature, time, and moisture content and tensile during heat treatment.
