EISM: An efficient ID-based signcryption scheme for multi-PKG multihop wireless networks of mobile hosts

Wireless ad hoc networks are self-configurable and autonomous networks and this type of networks serve as a good candidate to provide communications of many novel applications, including mission critical applications, mobile and pervasive computing, etc. Such networks are often composed of computation-constrained or resource-limited devices and without any underlying infrastructure. On the other hand, the wireless ad hoc networks must be …
