CONTROL OF ACCESS TO A SECONDARY SYSTEM

摘要

A method for controlling access of a user to a secondary system. A primary system receives, from a user system connected to the secondary system, first authentication information comprising an encryption of a random string. The encryption of the random string is a user-specific key. Second authentication information is generated from protected secondary authentication data stored in the primary system. Generation of the second authentication information includes applying the user-specific key to the protected secondary authentication data to generate the second authentication information. The second authentication information is provided to the secondary system to enable access of the user to the secondary system.
