SINGLE SIGN-ON METHOD AND SYSTEM

摘要

Disclosed is a single sign-on method, comprising: a client end generating a ciphertext according to a time string, a random code and a shared key shared with a server end after a user has signed on, and sending the time string, the random code and the ciphertext to the server end; the server end generating a verification string according to the received time string, random code and shared key, performing authentication on the user, and processing the sign-on request of the user according to the authentication result. A corresponding system is also provided. The operation of the single sign-on method and system provided in the present invention does not require support from a single sign-on server, making single sign-on simple to implement, malfunctions rare and costs relatively low.
