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.},
