A Low-Cost Solution for Frequent Symmetric Key Exchange in Ad-hoc Networks
: Next to authentication, secure key exchange is considered the most critical and complex issue regarding ad-hoc network security. We present a low-cost, (i.e. low hardware-complex...

Moduli for Testing Implementations of the RSA Cryptosystem
Comprehensive testing of any implementation of the RSA cryptosystem requires the use of a number of moduli with specific properties. It is shown how to generate a sufficient varie...

Breaking and repairing optimistic fair exchange from PODC 2003
In PODC 2003, Park, Chong, Siegel and Ray [22] proposed an optimistic protocol for fair exchange, based on RSA signatures. We show that their protocol is totally breakable already...

Trapdoor Hard-to-Invert Group Isomorphisms and Their Application to Password-Based Authentication
In the security chain the weakest link is definitely the human one: human beings cannot remember long secrets and often resort to rather insecure solutions to keep track of their ...

Non-interactive and reusable non-malleable commitment schemes
We consider non-malleable (NM) and universally composable (UC) commitment schemes in the common reference string (CRS) model. We show how to construct non-interactive NM commitmen...
