Compiling and securing cryptographic protocols

Compiling and securing cryptographic protocols

Protocol narrations are widely used in security as semi-formal notations to specify conversations between roles. We define a translation from a protocol narration to the sequences of operations to be performed by each role. Unlike previous works, we reduce this compilation process to well-known decision problems in formal protocol analysis. This allows one to define a natural notion of prudent ...

Compiling and Verifying Security Protocols

Securing Distance-vector Routing Protocols Securing Distance-vector Routing Protocols

The security requirements of distance-vector routing protocols are analyzed, their vulnerabilities identi ed, and countermeasures to these vulnerabilities are proposed. The innovation presented involves the use of mechanisms from the pathnding class of distancevector protocols as a solution to the security problems of distance-vector protocols. The result is the rst proposal to e ectively and e...

Programming Cryptographic Protocols

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. We embody these ideas in a cryptographic ...

Lecture Notes Cryptographic Protocols

ii iii Preface In this course, we focus on asymmetric techniques for cryptographic protocols, also considering proofs of security for various constructions. Motivating example: 'Sinterklaaslootjes trekken' is a Dutch tradition for buying presents and writing little poems, see, The same tradition is also known as " Secret Santa " , and a lot of websites and programs are available to help people ...
