%X In this work the encryption mechanism in MANET & WSN is considered. One of the very important parameters with MANET & WSN is its low computing power availability in its real time environment. Thus Security is an equal parameter in theses environments and equally important is its low computing power. This study is based on a Mathematical model [9] being used for encryption process, which consumes less power when compared to standard algorithms like 3 DES & RSA. In this work, the model is studied for its strength against noise which is an unavoidable phenomenon with MANET & WSN s. In the considered model, an empirical value is considered which is used as a key. The process is repeated for different timings which are used as time stamps in the encryption mechanism. Thus this model generates a distributed sequence which is used as sub key. The encrypted form of data during the transmission process will be subjected to errors due to some noise sources. These errors can affect the integrity of message or data transfer. The effects of these errors are checked in the present study by modeling the error as a random number having Gaussian Probability Density Function. The random number generator modeled is used to create values of the possible data errors. These errors are stored in a sub data base which can be made use of when corrupted sub key is received at the receiver¡¯s side. Thus when the received message after decryption is showing any ambiguity in its meaning or any integrity variations because of noise, it can be checked using the sub data base developed by the random number generator model.
