Cheating Detection and Cheater Identification in CRT-based Secret Sharing Schemes
نویسندگان
چکیده
In this paper we analyze the cheating detection and cheater identification problems for the secret sharing schemes based on the Chinese remainder theorem (CRT ), more exactly for Mignotte [1] and Asmuth-Bloom [2] schemes. We prove that the majority of the solutions for Shamir’s scheme [3] can be translated to these schemes and, moreover, there are some interesting specific solutions.

Design of Reliable and Secure Devices Realizing Shamir's Secret Sharing
Shamir’s secret sharing scheme is an effective way to distribute secret to a group of shareholders. The security of the unprotected sharing scheme, however, can be easily broken by cheaters or attackers who maliciously feed incorrect shares during the secret recovery stage or inject faults into hardware computing the secret. In this paper, we propose cheater detection and identification schemes...
متن کاملSecurity Analysis of a Hash-Based Secret Sharing Scheme
Secret sharing schemes perform an important role in protecting se-cret by sharing it among multiple participants. In 1979, (t; n) threshold secret sharing schemes were proposed by Shamir and Blakley independently. In a (t; n) threshold secret sharing scheme a secret can be shared among n partic-ipants such that t or more participants can reconstruct the secret, but it can not be reconstructed b...
متن کاملEfficient Threshold Secret Sharing Schemes Secure Against Rushing Cheaters
In this paper, we consider three very important issues namely detection, identification and robustness of k-out-of-n secret sharing schemes against rushing cheaters who are allowed to submit (possibly forged) shares after observing shares of the honest users in the reconstruction phase. Towards this we present five different schemes. Among these, first we present two k-out-of-n secret sharing s...

Visual Cryptographic technique has become an important field of study in modern cryptography. Visual cryptography (VC) has quite a few applications and some of them are authentication and identification, steganography, and image encryption. As the era demands the need of security and Visual Secret Sharing to resist cheating scenario is a Visual Cryptographic technique. VSS is simple as it is ea...
متن کاملA Secure Distributed Authentication scheme based on CRT-VSS and Trusted Computing in MANET
With the rapid development of MANET, secure and practical authentication is becoming increasingly important. The existing works perform the research from two aspects, i.e., (a)secure key division and distributed storage, (b)secure distributed authentication. But there still exist several unsolved problems. Specifically, it may suffer from cheating problems and fault authentication attack, which...
