  7. Abstract:
  8. Since the number of Internet users for the services such as e-applications is increasing rapidly, authentication constrains more latency as well as load to the system. It is due to large number of users whose identity needs to be checked and compared individually, and the number of simultaneous authentication requests in a specific time. To solve the stated issues, this thesis proposes a new definition of group authentication and describes group authentication protocols. Group authentication is the verification of identity of multiple requests of users at the same time. In this protocol, the authentication server inputs the multiple authentication requests in a function, and then applies some computations on them. After that, it compares the result to verify the identity of such users all at ones. Although group authentication can be used in various applications, we propose it for access control in secure IP multicast. In addition, in order to get more secure authentication, we combine it with one-time password authentication. The results show that group authentication reduces the load of the system as well as the latency of the authentication server process
