MANET is dynamic in nature without any fixed infrastructure and it is weak network and vulnerable to many kinds of attacks. The increased usage of wireless network and limited resource constraints of devices restricts the use of cryptography mechanisms for security in network. Safe data transmission along with data integrity and confidentiality are important aspects. To achieve these aspects the cryptography is a concept used to protect data from malicious nodes over untrusted network. The mechanisms based on trust are able to provide security in the network like access control. A salable security overlay is designed over trust-based routing for detecting and providing security services from misbehaving nodes. This paper is about transmission of secure data from malicious nodes and increases the network performance by using concept of cryptography over untrusted network for secure data and results are analyzed using ns2 simulator environment.
