About the Project

For two decades, numerous researchers have reported a close relationship between chaos and cryptography. Encryption based on chaos theory (for example logistic and tent maps) has several characteristics such as pseudo randomness, ergodicity and strong dependence on initial conditions etc. Due to highly unpredictable behaviour of chaotic maps, it can be used in multimedia data protection. The purpose of this project is to design light-weight encryption and watermarking schemes which can protect multimedia data from eavesdroppers. Furthermore, the proposed schemes will be tested against a number of benchmark security parameters.

Academic qualifications
A first degree (at least a 2.1) ideally in any related field i.e., Computer Science, Electrical Engineering, Electronics Engineering, Computer Engineering or Mathematics with a good fundamental knowledge of Mathematics, Programming Languages and Cryptography.

English language requirement
IELTS score must be at least 6.5 (with not less than 6.0 in each of the four components). Other, equivalent qualifications will be accepted. Full details of the University’s policy are available online.

Essential attributes
 Experience of fundamental Mathematics and Cryptography.
 Competent in at least one of the programming languages such as MATLAB, Python, C/C++ or any other related programming language.
 Knowledge of Mathematics, Basic Computing, Cyber Security, Encryption/Decryption Algorithms, and Machine Learning.
 Good written and oral communication skills.
 Strong motivation, with evidence of independent research skills relevant to the project.
 Good time management.
