Cryptology at Boise State University

Research Banner

Members of the Cryptology group are from the Department of Mathematics in the College of Arts and Science and from the Department of Computer Science in the College of Engineering. The group members are Liljana Babinkostova,  Marion Scheepers, Dianxiang Xu and Jyh-haw Yeh.


The Cryptology seminar meets every week to discuss our ongoing research and the research of others in our field. Students are welcome to attend.
Spring 2009 Schedule

BoiseCrypt Conference:

BoiseCrypt is a conference at which graduate students present the results of their graduate cryptology projects.
The Spring 2009 meeting of the Boise Graduate Cryptology Conference occurred on May 14, 2009.
The Fall 2009 meeting will take place during December 16 through 18.

Our Individual Cryptology Interests:

Liljana Babinkostova‘s cryptology research interests include algebraic structure of encryption schemas and hash functions, generalizations of protocols and solutions to improving their security.

Jyh-haw Yeh‘s cryptology research areas are randomness study of cryptographic algorithms using innovatory neural network approach. This methodology can be extended to test the randomness of more general Random Number Generator. Currently, he is also interested in cryptographic solutions for controlling access in multi-level security system.

Marion Scheepers‘s research interests in cryptology include mathematical modelling and analysis of security threats against practical information security systems.
