Session Based Access Control Mechanism Using ECC in WMN- A Review

Rahul V.Bambodkar, Avinash P. Wadhe

Wireless Mesh Networks (WMNs) are new emerging potential for strengthening Internet deployment and access. However, for large-scale deployment in some applications due to the lack of the satisfactory guarantees on security. The main challenges exposed to the security of WMNs come from the facts of the shared nature of the wireless architecture and the lack of globally trusted central authorities. A well-performed security framework for WMNs will contribute to network survivability and strongly support the network growth. A low-computational and scalable key management model for WMNs is to guarantee well-performed key management services and protection from unauthorized access. The RSA-based protocols have significant problems in terms of the bandwidth and storage requirements. Currently, the RSA algorithm requires that the key length be at least 1024 bits for long term security, however, it seems that 160 bits are sufficient for elliptic curve cryptographic functions. Thus, use of ECC in wireless mesh network ,can improved security substantially.
