Effective security is the foremost required facets in a Mobile ad-hoc network (MANET). So, the increase in demand for a secure and efficient mode of communication we are required to find the strength of the existing cryptography techniques. This work exhibits the use of a heuristic (partial search algorithm) approach that may present us with a proper adequate solution to an optimization problem of key selection, or generation. Today's era of computer s cryptography is a correlation of the conversion of plain text to ciphertext. It is observed that ciphertext is a text made that the receiver of the text can only possibly decide it to plain text. The process of conversion of plaintext to ciphertext is known as encryption and its vice-versa is known as decryption. Among the three types of cryptography techniques, namely Asymmetric key, Symmetric key and Hash Functions; Asymmetric Key cryptography (particularly RSA algorithm) is manipulated for work. We will stimulate swarm intelligence, computationally known as Particle Swarm Optimization (PSO) technique to reduce the key search space RSA algorithm. PSO is a technique of optimization and is used to find the optimized value of the key. The key will not be easy to be generated computationally be the intruders or detractors. We will determine a function, infer fitness function that is intended for the generation of the key within the reduced search space. This paper concentrates on the usage of PSO to find the key that is best in terms of security and effectiveness in a MANET.
