An anonymous user identification and key distribution technical protocol
Fuw-Yi Yang, Zhenwei Liu · International Journal of Advancements in Computing Technology · 2011
Owing to the dynamic development of the Internet and information technology, user can now access information and services provided by remote service provider through the Internet. The Internet is an open medium of communication; hence, in order to ensure private communication, this study designs an anonymous user identification protocol to determine user identities, as well as negotiating a private key for information encryption to prevent unauthorized user from accessing the communication data. Previous similar protocols employed timestamps to prevent replay attacks, requiring both sides of the communication to synchronize their clocks and causing a considerable burden on distributed systems. This study uses random numbers instead of synchronized clocks to prevent replay attacks, and thus reduces system construction and maintenance costs, besides being more applicable in distributed computer network systems. User identification has been reduced from four rounds of communications to three, providing evidence for the improvement in recognition efficiency and more effective bandwidth management.
