Secure identity tokens such as Electronic Identity (eID) cards are emerging everywhere. At the same time usercentric identity management gains acceptance. Anonymous credential sch...
CTC is a toy cipher designed in order to assess the strength of algebraic attacks. While the structure of CTC is deliberately weak with respect to algebraic attacks, it was claimed...
In this paper, we propose to replace the national identity card, currently used in many countries, by a personal device that allows its user to prove some binary statements about h...
Ensuring that every sensor node has the same code version is challenging in dynamic, unreliable multi-hop sensor networks. When nodes have different code versions, the network may...
