    • According to each embodiment of this invention, an encryption apparatus, decryption apparatus, and key generation apparatus based on a public-key cryptographic scheme whose security is based on the divisor finding problem of obtaining a divisor on an algebraic surface which is a difficult problem that has not been solved by contemporary mathematics are realized by an arrangement using, as a private key, a section D of algebraic curves (divisors) on a fibration X(x, y, t) of an algebraic surface X. This makes it possible to create a public-key cryptographic scheme which can ensure security even in the advent of a quantum computer, can be securely realized by even current computers, and can be realized in a low-power environment.
    • 根据本发明的每个实施例,一种基于公钥密码方案的加密装置,解密装置和密钥生成装置,其安全性基于获得代数表面上的除数的除数查找问题,该问题是一个难题, 当代数学没有得到解决,是通过使用代数曲线(除数)D代表代数曲线X(x,y,t)作为私钥的方式来实现的。这使得可以 创建公钥加密方案,即使在量子计算机出现的情况下也能保证安全性,即使是目前的计算机也能安全地实现,并且可以在低功耗的环境中实现。
