In this paper, we present a complete digital signature message stream, just the way the RSA digital signature scheme does it. We will focus on the operations with large numbers due to the fact that operating with large numbers is the essence of RSA that cannot be understood by the usual illustrative examples with small numbers[1].

Supervisor reduction procedure can be used to construct the reduced supervisor with a reduced number of states in discrete-event systems. The main concepts which are used in this procedure are control consistency of states, control cover, induced supervisor, and normality of the reduced supervisor w.r.t. the original supervisor. In this paper, it is proved that the reduced supervisor, construct...

Vehicular ad-hoc network (VANET) provides vehicle to vehicle and vehicle to RSAs (Road side antennas) communication. By using Multichannel TDMA MAC protocol, once per frame each node is ensured to access the Control channel which may cause delay at the receiver end. The Proposed “Vehicle Speed Synchronized protocol” will work on Control channel as well as on Service channel. The proposed protoc...
