— This paper proposes a new noncoherent detection system improved based on the differential chaos shift keying (DCSK) and the correlation delay shift keying (CDSK). In this schem...
High security network transactions require the checking of the revocation status of public key certificates. On mobile systems this may lead to excessive delays and unacceptable p...
The length-based approach is a heuristic for solving randomly generated equations in groups which possess a reasonably behaved length function. We describe several improvements of ...
The challenge-response technique is widely adapted for authentication of portable communication systems. For authentication the user can prove his/her identity via a secret shared...
