Data encryption standard (DES)

In this paper, a design of a chaos-based keystream generator (KSG) using a novel permutation technique with various two-dimensional patterns and a substitution technique with Z4 mapping is proposed. Initially, a chaotic function such as a logistic map is used to generate a pseudo-random number. Then these numbers are converted into binary sequences using binary mapping. In order to achieve statistical properties of the resultant binary sequences, a novel method of KSG is developed by considering parameters such as initial value “x0”, system parameter “r”, novel permutation techniques defined by 2-dimensional patterns, and substitution technique defined over Z4 transformation. The binary sequences so obtained are subjected to randomness tests by applying the National Institute of Standards and Technology (NIST) SP-800-22 (Revision 1a) test suite for investigation of its randomness properties to obtain suitable sequences which can be used as a key for cryptographic applications. From the results obtained, it is found that the binary sequences exhibit better randomness properties as per the cryptographic requirements.

Our research is the adoption of mutual authentication techniques on smart cards for Digital Rights Management (DRM) which is applied using network protocol engineering. We adopted the protocol engineering from the mutual authentication technique owned by the Mifare Desfire smart card. The tests carried out in our research are testing the security aspects of authentication and data confidentiality. Our authentication test is done by changing the client and server master keys that determine the success of authentication. Meanwhile, data confidentiality testing is carried out by tapping data sent from the client to the DRM server. When authentication by the client and server fails, the software is declared invalid and vice versa. The result of our research is the successful implementation of the adoption of the smart card's mutual authentication technique for application protection in DRM including authentication and encryption functions.
