TLS has been formally analyzed with the OTS/CafeOBJ method. In the method, distributed systems are modeled as transition systems, which are written in terms of equations, and it i...
Since bit and string oblivious transfer and commitment, two primitives of paramount importance in secure two- and multi-party computation, cannot be realized in an unconditionally ...
In an electronic cash (e-cash) system, Recoverability means once you have lost your e-cash, you still can get back the amount of e-cash that you have lost. Untraceability means no ...
In this paper we study the link between formal and cryptographic models for security protocols in the presence of a passive adversary. In contrast to other works, we do not conside...
Since fingerprint data are no secrets but of public nature, the verification data transmitted to a smartcard for oncardmatching need protection by appropriate means in order to ...
