Groups of people with mobile phones using short range connections like WiFi and Bluetooth to propagate messages can be modeled as, with regard to regular absence of end-to-end connection, Delay Tolerant Networks (DTNs). The study of message transmission speed in such kind of networks has attracted increasing attention in recent years. In this paper, we present a realistic framework to model the message...
Threshold signature schemes are useful in MANET because of the mobility and weak connectivity. Meanwhile, order-specified multi-signature schemes are valuable in some multi-level security systems. To meet such kind of requirements, we proposed a secure threshold order-specified multi-signature scheme based on RSA in this paper. The scheme is designed based on a modified threshold RSA signature scheme...
