We distinguish between two types of digital-signature based transactions: Identity-based and warranty-granting. In the relatively static (and traditional) of line “identity-based” transaction, a Certification Authority (CA) vouches for validity and veracity of data in a user ' s certificate. Whereas, in the more dynamic “warranty-granting” case, which we identify in this paper, a third-party entity vouches for a user on a per transaction basis while considering the user’s history and characteristics. Here, we provide a modefing for a warranty-granting transactions system and demonstrate its importance in the banking/financial/commercial setting. Warranty-granting systems can be implemented in one of several configurations based on the type of transaction and which party pays for the service (of acquiring the warranty). We discuss the primary configurations and then give a detailed specification for one of the discussed configurations.
