Abstract
Multi-server authenticated key agreement schemes have attracted great
attention to both academia and industry in recent years. However, traditional
authenticated key agreement schemes in the single-server environment are not suitable
for the multi-server environment because the user has to register on each server when
he/she wishes to log in various servers for different service. Moreover, it is unreasonable
to consider all servers are trusted since the server in a multi-server environment may be a
semi-trusted party. In order to overcome these difficulties, we designed a secure threefactor multi-server authenticated key agreement protocol based on elliptic curve
cryptography, which needs the user to register only once at the registration center in order
to access all semi-trusted servers. The proposed scheme can not only against various
known attacks but also provides high computational efficiency. Besides, we have proved
our scheme fulfills mutual authentication by using the authentication test method.
