Mobile Ad hoc Network (MANET) is becoming more and more popular in scientific, government, and general applications, but security system for MANET is still at infant stage. Currently, there are not many security systems that provide extensive security coverage for MANET. Moreover, most of these security systems assume nodes have infinite computation power and energy; an assumption that is not true for many mobiles. Versatile and Extensible System (VESS) is a powerful and versatile general-purpose security suite that comprises of modified versions of existing encryption and authentication schemes. VESS uses a simple and network-efficient but still reliable authentication scheme. The security suite offers four levels of security adjustments base on different encryption strength. Each level is designed to suit different network needs (performance and/or security), and the security suite allows individual end-to-end pair-wise security level adjustments; a big advantage for highly heterogeneous network. This versatility and adjustability let each pair of talking nodes in the network can choose a security level that prioritize either performance or security, or nodes can also choose a level that carefully balance between security strength and network performance. Finally, the security suite, with its existing authentication and encryption systems, is a framework that allows easy future extension and modification.
