The dynamic nature of Manet will always degrade the reliability in data transmission between the nodes. The manet is not protected against the attacks due to lack of security. The most common attack experienced by the Manet is black hole attack. This paper address the security oriented solution to prevent the black hole attack using the digital certificates to authenticate the routes selected during the route discovery process. The digital certificate authentication avoids the black hole node during the Route discovery itself. This methodology is implemented on AOMDV protocol. The algorithm is simulated using NS2.
