Abstract
Nowadays, security is necessary when transmitting confidential information over the network. One of the most important ways to provide data confidentiality is through cryptography. In this paper, we present a framework for testing and evaluating cryptographic algorithms. When evaluating block and stream ciphers, some basic properties should be tested: correct functional testing, passing statistical randomness testing, having good substitution boxes (S-boxes) and good permutation boxes (P-boxes) in their construction and providing a good throughput. The proposed framework receives the cryptographic algorithm as input and evaluates: the provided test vectors, the randomness of the generated data, the properties of the S-boxes and the P-boxes, the performance in terms of speed and throughput and provides a result, whether or not the algorithm is secure and can be used in cryptographic applications.
