摘要

电子商务(电子商务)交易需要安全通信,以保护敏感信息,如信用卡号、个人身份和财务数据,使其免遭未经授权的访问和欺诈。使用公钥加密技术进行加密对于确保电子商务交易的安全性至关重要。RSA和Rabin密码系统算法是广泛使用的公钥加密技术,它们的安全性是基于这样一个假设:将两个大素数的乘积分解成它的组成素数在计算上是不可行的。然而,RSA和Rabin密码系统的现有变体存在诸如高计算复杂度、低速度和易受因数分解攻击等问题。为了克服这个问题,本文提出了一种新的方法,在加密过程中引入假模的概念。提出的方法旨在通过在加密过程中引入假模量来提高Rabin密码系统的安全性,该假模量用于迷惑试图分解公钥的攻击者。在加密过程中,假模量被添加到原始模量中,攻击者无法区分两者。因此,攻击者无法对公钥进行分解,也无法访问电子商务交易过程中传输的敏感信息。采用定性和定量方法对该方法的性能进行了评价。定性措施,如视觉分析和直方图分析被用来评估所提出的系统的质量。为了量化所提出的方法的性能,使用了密文像素的出现次数熵和明文和密文的差分分析。当所提出的方法的复杂度与最近的Rabin密码系统的变体进行比较时,可以看出,所提出的方法(表示为O(ν × τ))比Rabin- p (O(ν))算法更复杂。

A Novel and Secure Fake-Modulus Based Rabin-Ӡ Cryptosystem
Electronic commerce (E-commerce) transactions require secure communication to protect sensitive information such as credit card numbers, personal identification, and financial data from unauthorized access and fraud. Encryption using public key cryptography is essential to ensure secure electronic commerce transactions. RSA and Rabin cryptosystem algorithms are widely used public key cryptography techniques, and their security is based on the assumption that it is computationally infeasible to factorize the product of two large prime numbers into its constituent primes. However, existing variants of RSA and Rabin cryptosystems suffer from issues like high computational complexity, low speed, and vulnerability to factorization attacks. To overcome the issue, this article proposes a new method that introduces the concept of fake-modulus during encryption. The proposed method aims to increase the security of the Rabin cryptosystem by introducing a fake-modulus during encryption, which is used to confuse attackers who attempt to factorize the public key. The fake-modulus is added to the original modulus during encryption, and the attacker is unable to distinguish between the two. As a result, the attacker is unable to factorize the public key and cannot access the sensitive information transmitted during electronic commerce transactions. The proposed method’s performance is evaluated using qualitative and quantitative measures. Qualitative measures such as visual analysis and histogram analysis are used to evaluate the proposed system’s quality. To quantify the performance of the proposed method, the entropy of a number of occurrences for the pixels of cipher text and differential analysis of plaintext and cipher text is used. When the proposed method’s complexity is compared to a recent variant of the Rabin cryptosystem, it can be seen that it is more complex to break the proposed method—represented as O(ɲ× τ) which is higher than Rabin-P (O(ɲ)) algorithms.
