Security Token and Federated Authentication Based on Elliptic Curve Groups Algorithm

This paper designed and completed a general algorithm based on elliptic curve encryption algorithm.The algorithm provides asymmetric encryption and digital signature,and it can effectively solve the illegal data access,and it can better solve data security problem under the stateless protocol.It provides an alternative solution to solve the data security access with stateless protocol in cloud distributed environment.This method has high efficiency and safety precautions,it prevents forgery and tamper with the unsafe factors,It has certain reference significance for the designing of the distributed data access.
