A Fast & Efficient Approach for Large Data Encryption & DecryptionUsing RSA Algorithm

Abstract

With the ever-increasing attacks on data and networks, every organization needs to protect, process, and
transmit their data securely through various cryptographic means. One such cryptographic algorithm is RSA (Rivest,
Shamir & Adleman). Nowadays, RSA is widely used as it a public – key cryptosystem, which generates 2 keys: Public
Key and Private key and requires both to decrypt data. Through this paper, the author has suggested afast and
efficient approach of the implementing the algorithm. Furthermore, the performance of both classical and proposed
method has been compared using various bit sizes.
