A stream cipher is a cryptosystem that typically encrypts a message by symbolic transforming it with the key stream (using for example the XOR logical operation). A block cryptosystem makes other additionally 2 operations. The confusion, also known as permutation, which shuffles the position of the symbols of the plain message (or “pixels” if the “message” is an image), so there is no change in the symbol value, and diffusion, which transforms the (values of the) symbols in the message
A second goal of this project is to create fast, efficient and secure state-of-the-art chaos-based block (often used to encode objects such as images or videos) and stream ciphers (often used to encode plain messages or digitalized signals).
APPLICATION PROCEDURE:
This project is advertised in relation to the research areas in the discipline of Physics and Applied Mathematics. Formal applications can be completed online: http://www.abdn.ac.uk/postgraduate/apply. You should apply for PhD in Physics, to ensure that your application is passed to the correct College for processing. NOTE CLEARLY THE NAME OF THE SUPERVISOR and EXACT PROJECT TITLE ON THE APPLICATION FORM.
Informal inquiries can be made to Dr M Baptista (murilo.baptista) with a copy of your curriculum vitae and cover letter. All general enquiries should be directed to the Graduate School Admissions Unit (cpsgrad@abdn.ac.uk).
