A primary system sends a random string to a user system that is connected to the secondary system. The user is logged on the user system. The primary system receives from the user system first authentication information including an encryption of the random string by a private key of the user. The primary system generates a user-specific key consisting of the encryption of the random string. The primary system generates second authentication information from protected secondary authentication data stored in the primary system via application of the user-specific key to the protected secondary authentication data. The primary system provides the second authentication information to the secondary system to enable access of the user to the secondary system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Control of access to a secondary system","description":"A method and system for controlling access of a user to a secondary system.
