This Paper describes the design and performance of a secure path with time-space cryptography for mobile ad-hoc networks. It works in the time domain for key distribution between source and destination as well as in the space domain for intrusion detection along the route between them. Even if public key encryption is more powerful and superior in distributing keys, the authors' scheme relies on symmetric key encryption because it is highly efficient and simple to implement. Thus, each node does not require any powerful hardware, thereby leading to a small and light device. The symmetric key cryptography shares a common secret key between source and destination.
