In this paper, simulated annealing guided traingularized encryption using multilayer perceptron generated session key (SATMLP) has been proposed for secured wireless communication. Both sender and receiver station uses identical multilayer perceptron and depending on the final output of the both side multilayer perceptron, weights vector of hidden layer get tuned in both ends. After this tunning step both perceptrons generates identical weight vectors which is consider as an one time session key. In the 1st level of encryption process traingularized sub key1 is use to encrypt the plain text. In 2nd level of encryption simulated annealing method helps to generates sub key 2 for further encryption of 1st level generated traingularized encrypted text. Finally multilayer perceptron generated one time session key is used to perform 3rd level of encryption of 2nd level generated encrypted text. Recipient will use same identical multilayer perceptron guided session key for performing deciphering process for getting the simulated annealing guided intermediate cipher text. Then using sub key 2 deciphering technique is performed to get traingularized encrypted text. Finally sub key 1 is used to generate the plain text. In this proposed technique session key is not transmitted over public channel apart from few data transfers are needed for weight simulation process. Because after synchronization process both multilayer perceptron generates identical weight vector which acts as a session key. Parametric tests are done and results are compared in terms of Chi-Square test, response time in transmission with some existing classical techniques, which shows comparable results for the proposed system.
