最近,两位日本人森井昌克和笠原正雄在《电子情报通信学会论文志》上提出了一种新的公开密钥密码体制。该密码体制在GF(p)上采用离散对数,把素域GF(p)上的离散对数问题作为陷井门单向函数。该密码体制“虽然在解密变换上与RSA大致相同,但在加密的时候,由于不必进行幂指数剩余运算,故便于采用并行处理技术来加以实 Recently, two Japanese Mori Hisako and Masashi Kasahara proposed a new public-key cryptosystem at the “Journal of Electronic Information and Communication Engineers.” The cryptosystem adopts discrete logarithm on GF (p) and discrete logarithm problem on prime GF (p) as trapdoor one-way function. Although this cryptosystem is almost the same as RSA in decryption conversion, it is convenient to use parallel processing technology to encrypt it since it is not necessary to carry out remaining arithmetic exponentiation
