Abstract
本发明在于提供一种利用非对称式加密算法建立、验证输入值的方法及其应用方法。其技术手段包括:利用非对称式加密算法,将原始/待验输入值当私钥,推导出公钥、又或者是将原始/待验输入值当种子,推导出私钥、公钥,接着再保留公钥,丢弃私钥,最后将公钥转作储存、待验暂存输入值,验证时,通过比对待验暂存、储存输入值两者是否一致,来判定验证是否成功。应用方法为利用前述密钥,以对称、非对称式加密算法及密钥协商算法,来做相依数据的加密、解密的使用。
Description
本发明涉及信息安全技术领域,尤指一种利用非对称式加密算法建立、验证输入值的方法及其应用方法。
现今的密码或序号的保护,主要是以明文的方式存放,或是以散列函数运算其散列值的方式,来取代明文存放。
但是散列值又容易因彩虹表的技术,而降低其保护性,所以在密码明文中加上盐值(Salt),再进行散列运算后存放,为目前的主流方式,可有效避免彩虹表的并行攻击手段。
暴力破解法(穷举法)可以破解任何的密码或序号,何时破解只是时间的问题。当前有几种方法,可以有效的降低暴力破解的成功率,包括:在限定的时间内,限制登入错误次数或来源IP地址,以及禁止使用过于简单的密码或序号;现今也常见使用一些特殊的密钥衍生函数(KDF),例如:PBKDF2、Scrypt、Bcrypt和ARGON2等,利用增加散列迭代次数与时间或资源成本,来抵御暴力破解法,然而就算如此,被暴力破解的成功率还是颇高。
另一方面,由于***被入侵或骇入等其他问题,而造成的数据外泄,也是对隐私保护的一大伤害,这是因为除了密码是以散列值或密钥的形式存放,现今的个人或其他种类的数据(信息)存放还是以明文为主,一旦***被入侵或骇入,所有数据(信息)将暴露于阳光下了,视为隐私保护的一大漏洞。
有鉴于此,如何提供一种能解决前述问题的利用非对称式加密算法建立、验证输入值的方法及其应用方法,便成为本发明欲改进的课题。
