rabin signature , decrypt and encrypt blocks using a serpent algorithm.

A project suggests an implementation of a data security mechanism in applications like Secure payment. The system has to include: • An implementation of serpent, symmetric cryptographic algorithms in one of the operation modes. The algorithm is intended to encrypt and decrypt the data. • An implementation of Rabin Signature scheme. • Implementation of the solution in any programming language like Python, Matlab, C++, etc. • It is not allowed to use toolkits like “import cryptography” of Python or include of C. An implementation should be self-provided. It is possible to use such an extension to the calculation of Hash Functions and Key generation. • GUI is not a necessary attribute, but a possibility to evaluate and to control the input and the output has to be.
