Nonmonotonic cryptographic protocols [PDF]
Proceedings The Computer Security Foundations Workshop VII, 2002 The paper presents a new method for specifying and analyzing cryptographic protocols. The method offers several advantages over previous approaches. The technique is the first to allow reasoning about nonmonotonic protocols, which are needed for systems that rely on the deletion of information.

Sequential rationality in cryptographic protocols [PDF]
ACM Transactions on Economics and Computation, 2010 Much of the literature on rational cryptography focuses on analyzing the strategic properties of cryptographic protocols. However, due to the presence of computationally-bounded players and the asymptotic nature of cryptographic security, a definition of sequential rationality for this setting has thus far eluded researchers.We propose a new framework ...

A Rational Approach to Cryptographic Protocols [PDF]
Mathematical and Computer Modelling, 2007 This work initiates an analysis of several cryptographic protocols from a rational point of view using a game-theoretical approach, which allows us to represent not only the protocols but also possible misbehaviours of parties. Concretely, several concepts of two-person games and of two-party cryptographic protocols are here combined in order to model ...

Hardware acceleration of number theoretic transform for zk‐SNARK
Engineering Reports, EarlyView., 2023 An FPGA‐based hardware accelerator with a multi‐level pipeline is designed to support the large‐bitwidth and large‐scale NTT tasks in zk‐SNARK. It can be flexibly scaled to different scales of FPGAs and has been equipped in the heterogeneous acceleration system with the help of HLS and OpenCL.

Programming Cryptographic Protocols [PDF]
, 2005 Cryptographic protocols are useful for trust engineering in distributed transactions. Transactions require specific degrees of confidentiality and agreement between the principals engaging in it. Moreover, trust management assertions may be attached to protocol actions, constraining the behavior of a principal to be compatible with its own trust policy.

Measurement-Device-Independent Two-Party Cryptography with Error Estimation
Sensors, 2020 We present an innovative method for quantum two-party cryptography. Our protocol introduces joint measurement and error estimation to improve the security of two-party cryptographic protocols. Our protocol removes the assumption of the attacker’s limited

Superposition Attacks on Cryptographic Protocols [PDF]
, 2014 Attacks on classical cryptographic protocols are usually modeled by allowing an adversary to ask queries from an oracle. Security is then defined by requiring that as long as the queries satisfy some constraint, there is some problem the adversary cannot solve, such as compute a certain piece of information.

Security protocol code analysis method combining model learning and symbolic execution
网络与信息安全学报, 2021 Symbolic execution can comprehensively analyze program execution space in theory, but it is not feasible in practice for large programs like security protocols, due to the explosion of path space and the limitation of difficulty in solving path ...

Is it possible to decide whether a cryptographic protocol is secure or not?
Journal of Telecommunications and Information Technology, 2002 We consider the so called ``cryptographic protocols`` whose aim is to ensure some security properties when communication channels are not reliable. Such protocols usually rely on cryptographic primitives.
