In this paper, we propose an improved RC6 encryption algorithm that have the same structure of encryption and decryption. So far, conventional RC6 algorithms have difference structure of encryption ...

This project demonstrates how to encrypt and decrypt image files using the AES (Advanced Encryption Standard) algorithm. It provides a secure way to transform an image into unreadable data and restore ...

This paper mainly focuses on the symmetric encryption and decryption of shared data. In the traditional symmetric encryption technology, sharing an identical key is safe for both communication parties ...

ADCRYPHAD is a new symmetric encryption algorithm designed for secure data transmission. It operates on 16-bit blocks of plaintext and uses a set of 10 unique S-Boxes and permutation patterns for ...

Bob: Attempt to decrypt the received message to reproduce the original plaintext. Eve: Attempt to intercept the encrypted message sent by Alice to Bob and decrypt it to reproduce the original ...

This paper presents a design of data encryption and decryption in a network environment using RSA algorithm with a specific message block size.

This has been sent via the cable which called RS-232 standard interface, which connected between the two computers, and receiving the cipher text in the second computer, and then it will be ...
