The Caesar Cipher is not suitable for serious security purposes, as it is relatively easy to break. Non-alphabetic characters remain unchanged during encryption/decryption.

Equation-Based-Shift-Cipher A Python-based encryption and decryption tool that transforms text messages into numerical sequences using a customizable, non-repeating equation as the encryption key and ...

Encryption and Decryption of Marker Based 3-Dimensional Augmented Reality Image Using Modified Hill Cipher Technique for Secure Transfer ...

In this paper, the authors used the stream cipher which is the best way with the algorithm Geffe generator with a specific length to encryption the information from plain text in the first compute.

Abstract: We propose secure digital-coherent system utilizing high-speed encryption/decryption through fiber and simplified digital back propagation (DBP). Negligible penalty is observed by de-tecting ...
