Secure Mobile Adhoc Network using AES and RSA

Anshul Jain, Sumeet Dhillion, Yogendra Jain
Mobile adhoc network has security issues over a large number of years. To maintain security several algorithms for authentication, authorization, integrity, non repudiation and confidentiality are proposed by various authors. In this paper security for MANET has been proposed using RSA, AES and SHA512 algorithm. RSA has been used for key generation, AES for symmetric encryption. Using AES both variable length and fixed length encryption schemes are compared. It is found that variable length
