Evaluating communication strategies for public agencies: transparency, opacity, and secrecy
This paper analyses in a simple global games framework welfare effects stemming from different communication strategies of public agencies if strategies of agents are strategic complements: communication can either be fully transparent, or the agency can opaquely publish only its overall assessment of the economy, or it can keep information secret. It is shown that private agents put more weigh...
متن کاملSecrecy 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 کاملPerfect Secrecy and Statistical
There are two key properties of the above. First, given only c, Eve should not be able to learn what m is. Second, Dec(Enc(m)) = m, so that Bob can accurately determine the message that Alice wanted to send. Creating functions Enc and Dec which satisfy this is a fundamental problem of cryptography. But given the above encryption scheme, knowing what these functions are is enough for anyone to d...
متن کاملSecrecy and Group Creation
We add an operation of group creation to the typed πcalculus, where a group is a type for channels. Creation of fresh groups has the effect of statically preventing certain communications, and can block the accidental or malicious leakage of secrets. Intuitively, no channel belonging to a fresh group can be received by processes outside the initial scope of the group, even if those processes ar...
