This paper presents a secure constant-round password-based group key exchange protocol in the common reference string model. Our protocol is based on the group key exchange protoco...
Since current computer infrastructures are increasingly vulnerable to malicious activities, intrusion detection is necessary but unfortunately not sufficient. We need to design ef...
Programmers of large-scale trusted systems need tools to simplify tasks such as replicating services or data. Group communication systems achieve this via various flavors of relia...
In the last ten years, multivariate cryptography has emerged as a possible alternative to public key cryptosystems based on hard computational problems from number theory. Notably,...
This paper examines problems persons with deafblindness have when using computers and it analyses how we can approach these problems in the redesign of a communication tool. A qual...
