An Integration of Cryptography and Coding Theory

The usage of the internet is increasing, so the message transmission must be protected. The real message is called plaintext. When a message is sent, it is encrypted into ciphertext, and it is assumed that it will reach the receiver without any errors. But in real situations, errors can occur at any time. The RSA algorithm is applied for both encryption and decryption to ensure message security. After transmission error detection and correction are performed using coding techniques, if the error is a single bit, it is corrected using the Hamming code, and otherwise, the BCH code is used. This paper combines cryptography and coding theory to improve security and reliability in the secure communication system.
