摘要
随着信息科技的发展,生活节奏的加快,越来越多的人选择购买充值卡进行必要的储值,充值卡的安全性显得越来越重要。随着椭圆曲线在加密解密方面的广泛应用,在熟悉了椭圆曲线加密解密的一般原理之后,可以基于椭圆曲线设计充值卡的加密方案,其安全性依赖于椭圆曲线中的离散对数问题。
With the development of information technology and the gradually accelerated pace of life,more and more people prefer to purchase prepaid card for recharge necessarily.Therefore it is particularly important for the safety of prepaid cards.With the wide application of elliptic curve in encryption and decryption program,this paper design a cryptographic scheme on the basis of a well-rounded understanding of elliptic curve.The security of the cryptographic scheme is based on the difficulty of elliptic curve discrete logarithm.
