Research Interests

I am lecturer in Mathematics in the information security group at Royal Holloway and Bedford New College. I also lecture the course on "Standards and Evaluation Criteria" for the M.Sc. course in Information Security. More information about the Standards and Evaluation Criteria course can be found here and here. Previously I had been employed as a research assistant studying security of the ciphers submitted to the NESSIE programme sponsored by the European union and as an EPSRC Junior Research Fellow. My main cryptographic interests are asymmetric ciphers and their provable security properties. First, let me present the books that I have written or edited. ~ 2005 ~ 1 A. W. Dent and C. J. Mitchell.
