Formal Verification of Cardholder Registration in SET

SET Cardholder Registration : the Secrecy Proofs ( Extended

A short introduction to two approaches in formal verification of security protocols: model checking and theorem proving

In this paper, we shortly review two formal approaches in verification of security protocols; model checking and theorem proving. Model checking is based on studying the behavior of protocols via generating all different behaviors of a protocol and checking whether the desired goals are satisfied in all instances or not. We investigate Scyther operational semantics as n example of this...

Web Service Choreography Verification Using Z Formal Specification

Web Service Choreography Description Language (WS-CDL) describes and orchestrates the services interactions among multiple participants. WS-CDL verification is essential since the interactions would lead to mismatches. Existing works verify the messages ordering, the flow of messages, and the expected results from collaborations. In this paper, we present a Z specification of WS-CDL. Besides ve...

Verifying the SET registration protocols

SET (Secure Electronic Transaction) is an immense e-commerce protocol designed to improve the security of credit card purchases. In this paper we focus on the initial bootstrapping phases of SET, whose objective is the registration of cardholders and merchants with a SET certificate authority. The aim of registration is twofold: getting the approval of the cardholder’s or merchant’s bank, and r...

Design and formal verification of DZMBE+

In this paper, a new broadcast encryption scheme is presented based on threshold secret sharing and secure multiparty computation. This scheme is maintained to be dynamic in that a broadcaster can broadcast a message to any of the dynamic groups of users in the system and it is also fair in the sense that no cheater is able to gain an unfair advantage over other users. Another important feature...
