Abstract

The implementation of the RSA (Rivest-Shamir-Adleman) cryptography algorithm, which is one of the most commonly used public-key cryptography algorithms. RSA provides high security and is widely used in information security applications such as data encryption, digital signature generation, and key exchange. This research documents the step-by-step implementation process of the RSA algorithm in classical cryptography, including key generation, data encryption, and decryption, leading to the generation of encryption and decryption tables for a specific key.

Abstract

Science and technology development has made human activities turn into cyberspace activities, one of which is buying and selling. Shopee is one of the e-commerce platforms available. As an online-based platform, Shopee certainly stores lots of user data. Since August 1st, 2022, Shopee has made a policy regarding user data security by censoring the buyer’s name and phone number in the ordering process. This research discusses one way to secure buyer data through cryptography with the concept of super encryption. This concept itself combines more than one encryption method with the goal to create ciphertext that is difficult to solve. The chosen combination for this research is the modified Hill Cipher algorithm before proceeding with the Rail Fence Cipher encryption. Result obtained in this research is possible to be applied in Shopee buyer data security system, seen from the difficulty level of the ciphertext decryption.
