A Formal Semantics for Protocol Narrations
نویسندگان
چکیده
Protocol narrations are an informal means to describe, in an idealistic manner, the functioning of cryptographic protocols as a single intended sequence of cryptographic message exchanges among the protocol’s participants. Protocol narrations have also been informally “turned into” a number of formal protocol descriptions, e.g., using the spi-calculus. In this paper, we propose a direct formal operational semantics for protocol narrations that fixes a particular and, as we argue, wellmotivated interpretation on how the involved protocol participants are supposed to execute. Based on this semantics, we explain and formally justify a natural and precise translation of narrations into spi-calculus.

The Comparative Semantics of ‘Recitation’ and ‘Chanting’ in the Holy Quran and Hadith’s Viewpoint
In linguistics, a study of the relation between word and meaning is called semantics. Semantics is a term for referring to study the meaning of elements of a language, particularly to study the real context of sentences and phrases of a language. The meaning of ‘recitation’ and ‘chanting’ in terms of Quranic, Hadith and idiomatic applications will be identified in this p...
متن کاملA 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...
متن کاملReverse Engineering of Network Software Binary Codes for Identification of Syntax and Semantics of Protocol Messages
Reverse engineering of network applications especially from the security point of view is of high importance and interest. Many network applications use proprietary protocols which specifications are not publicly available. Reverse engineering of such applications could provide us with vital information to understand their embedded unknown protocols. This could facilitate many tasks including d...
متن کاملSecurity Protocols and their Properties
Specifications for security protocols range from informal narrations of message flows to formal assertions of protocol properties. This paper discusses those specifications, emphasizing authenticity and secrecy properties. It also suggests some gaps and some opportunities for further work. Some of them pertain to the traditional core of the field; others appear when we examine the context in wh...
متن کاملCompiling 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 ...
