DYNAMIC TOKEN SEED KEY INJECTION AND DEFORMATION METHOD

摘要

The present invention discloses a dynamic token seed key injection and deformation method. The method comprises steps of: generating in advance an initial seed key for a token and injecting the initial seed key into the token during manufacture; when distributing the token to an end user, performing an activation operation, and obtaining a new seed key, which is the final seed key for the future work of the token, by performing an operation based on an active code and the initial seed key; meanwhile, introducing the initial seed key into a dynamic password authentication system which performs the same deformation operation for the seed key as that performed in the token to obtain the same new seed key. After the activation operation in the token and the authentication system in this way, the final new seed key is different from the initial seed key injected by the token manufacturer, so that the privacy of the seed key is strengthened.
