Abstract
The present invention defines a strong authentication token for generating different dynamic credentials for different application providers comprising an input interface providing an output representing an application provider indicator; a secret key storage for storing one or more secret keys; a variability source for providing a dynamic variable value; a key providing agent for providing an application provider specific key as a function of said application provider indicator using one or more keys stored in said secret key storage; a cryptographic agent for cryptographically combining said application provider specific key with said dynamic variable value using symmetric cryptography; a transformation agent coupled to said cryptographic agent for transforming an output of said cryptographic agent to produce a dynamic credential; and an output interface to output said dynamic credential.The present invention defines furthermore a method to manage the secret keys of strong authentication tokens that can generate dynamic credentials for more than one supported application provider or application provider group using different secret keys for each supported application provider or …
