Introduction of Cryptographic Protocols

2012
Cryptographic protocols are communication protocols which are designed to provide security assurances of various kinds, using cryptographic mechanisms. This chapter gives a brief introduction of cryptographic protocols and the reason why we study these protocols.

Delayed-Input Cryptographic Protocols

2017
The delayed-input witness-indistinguishable proof of knowledge of Lapidot and Shamir (LS) [CRYPTO 1989] is a powerful tool for designing round-efficient cryptographic protocols. Since LS was designed for the language of Hamiltonian graphs, when used as subprotocol it usually requires expensive NP reductions.

Fischer's cryptographic protocols

Proceedings of the twenty-second annual symposium on Principles of distributed computing, 2003
This note is prepared for Michael Fischer's 60th birthday celebration at PODC 2003. In it, I briefly describe some of Michael Fischer's work on distributed cryptographic protocols.

Cryptographic protocols and voting

1994
Three protocols related to computer voting are presented. First protocol is an efficient ANDOS protocol which is based on a natural cryptographic assumption. The other two protocols attack a difficult problem in computer voting: buying of votes. We manage to solve this problem but our protocols are impractical in large-scale elections.

Probabilistic Termination and Composability of Cryptographic Protocols

Journal of Cryptology, 2016
When analyzing the round complexity of multi-party computation MPC, one often overlooks the fact that underlying resources, such as a broadcast channel, can by themselves be expensive to implement. For example, it is impossible to implement a broadcast channel by a deterministic protocol in a sub-linear in the number of corrupted parties number of ...

Cryptography and cryptographic protocols

Distributed Computing, 2003
We survey the paradigms, approaches and techniques used to conceptualize, define and provide solutions to natural cryptographic problems. We start by presenting some of the central tools (e.g., computational difficulty, pseudorandomness, and zero-knowledge proofs), and next turn to the treatment of encryption and signature schemes.

Collusion analysis of cryptographic protocols

Proceedings of GLOBECOM'96. 1996 IEEE Global Telecommunications Conference, 2002
As network applications such as electronic commerce proliferate, complex communications protocols that employ cryptographic building blocks, such as encryption and authentication, will become more common. We view a cryptographic protocol as a process by which information is transferred among some users and hidden from others.

Verifying Cryptographic Protocols with Subterms Constraints

2007
Known protocol analysis techniques consider protocols where some piece of information expected in a protocol message is located at a fixed position. However this is too restrictive to model web-services where messages are XML semi-structured documents and where significant information (such as name, signature, ...) has to be extracted from nodes ...
