ON COMPUTATIONAL INTRACTABILITY ASSUMPTIONS IN CRYPTOGRAPHY
, 2011
"... In cryptographic protocols, honest parties would prefer that their security is assured even in presence of adversarial parties who have unbounded computational power. Information theoretic secure realization of cryptographic primitives provides such guarantees; but for most tasks such strong securit ..."

for efficient algorithms, are called computational intractability assumptions. In this work, we motivate a study of computational intractability assumptions which is goal driven and lends support to the fundamental nature of some of the traditional assumptions beyond being historical accidents. Secure multi
On the Computational Intractability of Analytic Tableau Methods
"... The method of analytic tahlmwx is HismmrH with respect to the notion of computational complexity. The dan of formulas that wu fint identified to be intractable for the tableau method k examined, and an explicit proof of this intractability b presented. A minor addition (factoring) that lead * to fas ..."

Cryptographic Complexity Classes and Computational Intractability Assumptions
"... Which computational intractability assumptions are inherent to cryptography? We present a broad framework to pose and investigate this question. We first aim to understand the “cryptographic complexity ” of various tasks, independent of any computational assumptions. In our framework the cryptograph ..."

An Information Hiding Method based on Computational Intractable Problems ⋆
"... This paper presents an information hiding method that can be used for proving copyright ownership of a digital object. In contrast with other methods, the identity of the owner of the object is proved by the owner’s ability to demonstrate knowledge of a certain property of the signature. The method ..."

utilizes Zero Knowledge Interactive Proof (ZKIP) protocols for computationally intractable, or NPcomplete, problems and in particular for the 3coloring problem. This problem requires an assignment of a color out of three available colors to the vertices of a graph so that no two adjacent vertices have
Sufficient Conditions for the Computational Intractability of Generic Group Problems
"... Abstract. The generic group model is a valuable methodology for analysing the computational hardness some numbertheoretic problems used in cryptography. Although generic hardness proofs exhibit many similarities, still the computational intractability of every newly introduced problem needs to be p ..."

, 1988
"... Under the assumption that each pair of participants em communieatc secretly, we show that any reasonable multiparty protwol can be achieved if at least Q of the Participants am honest. The secrecy achieved is unconditional, It does not rely on any assumption about computational intractability. 1. ..."
