Computationally secure multiple secret sharing: models, schemes, and formal security analysis

S. Mashhadi

Volume 7, Issue 2 , July 2015, Pages 91-99


  A multi-secret sharing scheme (MSS) allows a dealer to share multiple secrets among a set of participants. in such a way a multi-secret sharing scheme (MSS) allows a dealer to share multiple secrets among a set of participants, such that any authorized subset of participants can reconstruct the secrets. ...  Read More

Efficient implementation of low time complexity and pipelined bit-parallel polynomial basis multiplier over binary finite fields

B. Rashidi; R. Rezaeian Farashahi; S. M. Sayedi

Volume 7, Issue 2 , July 2015, Pages 101-114


  This paper presents two efficient implementations of fast and pipelined bit-parallel polynomial basis multipliers over GF (2m) by irreducible pentanomials and trinomials. The architecture of the first multiplier is based on a parallel and independent computation of powers of the polynomial variable. ...  Read More

EEH: AGGH-like public key cryptosystem over the eisenstein integers using polynomial representations

R. Ebrahimi Atani; Sh. Ebrahimi Atani; A. Hassani Karbasi

Volume 7, Issue 2 , July 2015, Pages 115-126


  GGH class of public-key cryptosystems relies on computational problems based on the closest vector problem (CVP) in lattices for their security. The subject of lattice based cryptography is very active and there have recently been new ideas that revolutionized the field. We present EEH, a GGH-Like public ...  Read More

A collusion mitigation scheme for reputation systems

M. Niknafs; S. Dorri Nogoorani; R. Jalili

Volume 7, Issue 2 , July 2015, Pages 151-166


  Reputation management systems are in wide-spread use to regulate collaborations in cooperative systems. Collusion is one of the most destructive malicious behaviors in which colluders seek to affect a reputation management system in an unfair manner. Many reputation systems are vulnerable to collusion, ...  Read More
