A review paper of an encryption scheme using network coding for energy optimization in MANET

Mobile ad-hoc network is a collection of mobile nodes which forms an instant network without fixed topology and can be arranged dynamically. Energy saving and security are important issue in MANET. Network coding technique is used to reduce energy consumption by less transmissions in MANET. To achieve a security, there are many encryption scheme are available. Out of which p-coding technique is lightweight encryption scheme which provides confidentiality. P-coding is to let the source randomly permute the symbol of each packet. So eavesdropper can't obtain the meaningful information without knowing the permutation encryption function and coding vector.
