In recent years, a lot of research is focused on wireless adhoc network, which is focused on field of performance, security, and energy. This paper addressed the difficulties and challenges facing the adhoc networks in security. Transmission of extremely sensitive information via one single path is not advisable as the information can easily be lost or hacked if the individual path is not fully trusted. To avoid this threat sender may want to send multiple copies through multiple disjoint paths. But this increases the risk of information leakage. Shared cryptography tries to address this concern. In this paper Novel Security Scheme for Wireless Adhoc Networks (NSS) is studied and some serious drawbacks of NSS have been realized. To overcome these drawbacks, Enhanced Novel Security Scheme (ENSS) is proposed. Classical approaches of secret sharing have high computational complexity. While proposed approach (ENSS) provides high security with moderate computational complexity results in less power consumption.
