These mentioned applications require secure and reliable communication as a prerequisite for using ad hoc networks .
Designing ad hoc network routing protocols is a challenging task which makes securing ad hoc networks more and more challenging.
Hybrid encryption technique (symmetric key encryption/public key encryption) is used to improve performance; where symmetric keys are used to encrypt routing data to authenticate and authorize node sending data, while, public keys are used for the exchange of symmetric keys between nodes.
We found that DSR may be secured using mobile agents with competitive performance.
For distributed systems that use remote procedure calls, server computers are designed to offer a fixed set of services.
