基于交织Goppa码的公钥密码体制

A Public-Key Cryptosystem from Interleaved Goppa Codes

Molka Elleuch, Antonia Wachter-Zeh, Alexander Zeh

摘要:

提出了一种基于交织Goppa码的公钥密码体制。该方案是基于加密多个密文相同的Goppa码,并添加一个突发错误。可能的攻击概述和几个参数的选择的密钥大小进行比较,为相同的安全级别的已知方案。例如,对于安全级别128位,我们获得696 Kbits的密钥大小,而基于使用列表解码的Goppa码的经典McEliece方案需要1935 Kbits的密钥大小。

英文摘要:

In this paper, a code-based public-key cryptosystem based on interleaved Goppa codes is presented. The scheme is based on encrypting several ciphertexts with the same Goppa code and adding a burst error to them. Possible attacks are outlined and the key size of several choices of parameters is compared to those of known schemes for the same security level. For example, for security level 128 bits, we obtain a key size of 696 Kbits whereas the classical McEliece scheme based on Goppa codes using list decoding requires a key size of 1935 Kbits.
