A Dual Key Authentication and Key Exchange Protocol Based on USB Key
Chen Xiao-su · Computer Engineering and Science · 2007
Authentication protocols based on traditional USB Key are unable to process complex encryption/decryption data and lead to many disadvantages.Based on the features that USB Key with a smartcard chip can process complex encryption/decryption and generate random keys,this paper presents a dual key authentication and key exchange protocol(DKAKEP).DKAKEP integrates the random number authentication,the one-time session key,the AES encryption and the secure hash algorithm,provides secure and fast authentication and key exchange,and supports many useful features such as fast key change,supporting multiple hash algorithms and needing no time synchronous mechanisms.The security analysis and practical application indicate that DKAKEP provides good practicality,security and reliability.
