Modified GPT Cryptosystem for Information Network Security
To provide information security in network we use the public key GPT (Gabidulin–Paramonov–Tretiyakov) cryptosystem based on rank codes. This cryptosystem was the subject of several attacks. Some of them were structural attacks, others were decoding attacks. In our opinion the most dangerous are structural attacks because decoding attacks can be prevented by proper choice of parameters. To preve...
متن کاملModified Niederreiter type of GPT cryptosystem based on reducible rank codes
GPT public key cryptosystem was proposed by Gabidulin, Paramonov and Tretjakov in 1991. This cryptosystem is based on rank error correcting codes. The main advantage of using rank codes in cryptography is that, it has smaller key size as compared to other code based public key cryptosystems. Several attacks against this system were published and some modifications were also proposed withstandin...
متن کاملGPT Meets PSR
We present a case study in confronting the GPT generalpurpose planner with the challenging power supply restoration (PSR) benchmark for contingent planning. PSR is derived from a real-world problem, and the dif£culty of modeling and solving it contrasts with that of the purely arti£cial benchmarks commonly used in the literature. This confrontation leads us to improve general techniques for con...
متن کاملImproved Cryptanalysis of Rank Metric Schemes Based on Gabidulin Codes
We prove that any variant of the GPT cryptosystem which uses a right column scrambler over the extension field as advocated by the works of Gabidulin et al. with the goal to resist to Overbeck’s structural attack are actually still vulnerable to that attack. We show that by applying the Frobenius operator appropriately on the public key, it is possible to build a Gabidulin code having the same ...
متن کاملLogical Data Scrambler for High Speed Application
Nowadays, the requirements of high speed applications are increasing day by day. So, to achieve such type of data transfer rate in OTN (optical transfer network) protocol a proposed architecture has been designed. This architecture is called as logical scrambler architecture which is specifically designed for OTN protocol & specifications of their logical resources. The logical scrambling archi...
