Abstract

Claim based identities are transformed to a set of credentials and securely stored in a secure data store using a number of encryption schemes. The credentials are then used to authenticate applications requiring specific credential types. For each call to the secure store system, a client application may provide a claims token issued by a trusted source, which is used to search for corresponding credentials in the secure data store if the credentials have been created previously for the user.
