Secrecy logic: S -secrecy structures
Let S = 〈L, S〉 be a deductive system. An S -secrecy logic is a quadruple K = 〈FmL(V ),K,B, S〉 , where FmL(V ) is the algebra of L-formulas, K,B are S -theories, with B ⊆ K and S ⊆ K such that S ∩ B = ∅ . K corresponds to information deducible from a knowledge base, B to information deducible from the publicly accessible (or browsable) part of the knowledge base and S is a secret set, a set of s...
متن کاملSecrecy-Preserving Reasoning using Secrecy Envelopes
Inmany applications of networked information systems, the need to share information often has to be balanced against the need to protect secret information from unintended disclosure, e.g., due to copyright, privacy, security, or commercial considerations. We study the problem of secrecy-preserving reasoning, that is, answering queries using secret information, whenever it is possible to do so,...
متن کاملNew Functions for Secrecy on Real Protocols
In this paper, we present new functions for secrecy in cryptographic protocols:the witnessfunctions. A witness-function is a protocol-dependent function that is able to prove the correctness of a protocol through its growth. It bases its calculation on the static part of a message only in a role-based specification by using derivation techniques. We show here how to build them. Then, we run an ...
متن کاملOn information-theoretic secrecy for wireless networks
In this paper we summarize our recent work on information-theoretically secure wireless relay network communication. In such communication, the goal is to send information between two special nodes (“source” and “destination”) in a (memoryless) network with authenticated relays, where the secrecy is with respect to a class of eavesdroppers. We develop achievable secrecy rates when authenticated...
متن کاملGeorge VOUTSADAKIS SECRECY LOGIC : PROTOALGEBRAIC S - SECRECY LOGICS
A b s t r a c t. In recent work the notion of a secrecy logicS over a given deductive system S was introduced. Secrecy logics capture the essential features of structures that are used in performing secrecy-preserving reasoning in practical applications. More precisely, they model knowledge bases that consist of information, part of which is considered known to the user and part of which is to ...
