— I am a Ph.D. candidate, under the direction of Prof. George Stephanides, @ the department of Applied Informatics, University of Macedonia, Thessaloniki, Greece, EU. — My current research is in the field of public key cryptography (PKC). I mainly focus on cryptosystems based on bilinear pairings over elliptic curve (EC) points. In parallel, I study some other security related topics, such as passdoodle techinques, user-password analysis, keyboard acoustic attacks and many more ...
