Research Paper (undergraduate) from the year 2019 in the subject Computer Science - IT-Security, , course: Computer Science and Engineering, language: English, abstract: The purpose of this study is to improve the strength of RSA Algorithm and at the same time improving the speed of encryption and decryption. RSA algorithm is named after Ron Rivest, Adi Shamir and Len Adleman, who invented it in 1977-78. The RSA crypto-system is the most widely- used public key cryptography algorithm in the world. Its security is based on the difficulty of factoring large integers. This paper presents an improved RSA algorithm which is superior to the original RSA algorithm in terms of strength of encryption and speed of encryption and decryption. This includes the strengthened form of RSA algorithm along with the architecture of the proposed algorithm. A cloud based database is used store the keys in advance. The modified RSA algorithm is compared on various aspects with the original RSA algorithm and the proposed algorithm certainly improve the strength and speed of computation.
