Abstract

The objective of this research is to develop an adaptive cryptographic protocol, which allows users to select an optimal cryptographic strength and algorithm based upon the hardware and bandwidth available and allows users to reason about the level of security versus the system throughput. In this constantly technically-improving society, the ability to communicate via wireless technology provides an avenue for delivering information at anytime nearly anywhere. Sensitive or classified information can be transferred wirelessly across unsecured channels by using cryptographic algorithms. The research presented will focus on dynamically selecting optimal cryptographic algorithms and cryptographic strengths based upon the hardware and bandwidth available. The research will explore the performance of transferring information using various cryptographic algorithms and strengths using different CPU and bandwidths on various sized packets or files. This research will provide a foundation for dynamically selecting cryptographic algorithms and key sizes. The conclusion of the research provides a selection process for users to determine the best cryptographic algorithms and strengths to send desired information without waiting for information security personnel to determine the required method for transferring. This capability will be an important stepping stone towards the military’s vision of future Net-Centric Warfare capabilities.
