An Authentication Protocol Based on USB-KEY
Ding Shiming · Microcomputer Development · 2005
Summarizes the authentication methods and protocols,and then gives a protocol based on USB-KEY from the side of cryptology and network security which is aiming at localization of biology authentication and high cost of PKI.With the feature that USB-KEY hardware produces randomicity and calculates and restores data,the protocol uses randomicity,asynchronous time mark,DES cryptoguard,and MD5 algorithm to accomplish data integrality,data security and session key to make the protocol easy and useful and safety.At last,this paper makes security analysis and proves that the protocol is secure against stolen-verifer and replay-attacks and the-middle-people attacks.
