Abstract: RSA is one of the most widely used asymmetric encryption algorithms for secure data exchange. However, the traditional RSA approach faces several challenges, including limited performance, ...

The goal of this project is to provide simple, portable and compatible code (data encrypted in Python can be decrypted in PHP, and so on). The encryption algorithm used is AES in CBC and CFB mode.

Abstract: Proxy Re-Encryption (PRE) has proven effective for implementing encrypted access control in cloud environments. However, existing PRE schemes remain inadequate for scenarios requiring ...
