New Block Cipher Encryption Based On OTP Algorithm

Abstract

The current world revolves around encryption. Every time a mobile phone call is made, a credit card is used in a store or on the Internet, or to withdraw cash from an ATM, encryption ensures the transaction’s secrecy and security. In this paper, we propose a high secure practical OTP Algorithm using CTR encryption. In this paper, we provide a solution that is unbreakable by quantum computing. Quantum computing is the highest threat facing encryption nowadays. SHA-512 and PRNG are applied in this paper within the proposed mathematical model. and the model was deeply analyzed. Also, security and practicality were proven.
