但传统的基于Goppa码的McEliece密码体制存在公钥体积大,传输速率低等缺陷.而基于QC-MDPC码的McEliece密码体制,可以有效地克服以上两个缺陷,因此对QC-MDPC码展开研究很有必要.本文在原QC-MDPC码和McEliece密码体制攻击算法的基础上,提出了基于QC-MDPC码的McEliece密码体制算法,同时从性能角度对比分析该算法存在的...

QC-MDPC-McEliece is a recent variant of the McEliece encryption scheme which enjoys relatively small key sizes as well as a security reduction to hard problems of coding theory. Furthermore, it remains secure against a quantum adversary and is very well suited to low cost implementations on ...

In this paper we present a public key cryptosystem of McEliece based on the correcting codes, using two types of correcting codes; QC-MDPC and Goppa correcting codes. This latter seems very interesting considering its two characteristics, namely the power of correction and the efficient decoding ...
To overcome this problem, we propose an improved McEliece cryptosystem based on quasi-cyclic quasi moderate-density parity-check (QC-QMDPC). In this cryptosystem, a stamp generation function which is based on the pseudorandom sequence is designed to resist the message-resend attack. The random ...
