Certificate Less Key Management Scheme in Manet Using Threshold Cryptography
Shaheena Khatoon, Balwant Singh Thakur · International Journal of Network Security & Its Applications · 2015
In mobile adhoc networks (MANETs) an efficient and secure key management scheme is extremely crucial.Key management schemes for MANETs are mainly based on identity-based public key cryptography (ID-PKC) or certificate-based public key cryptography, both of which has their inherit problem.The ID-PKC has the key escrow problem and certificate based cryptography have a high computational costs of certificates deployment.In this paper, we present a distributed key management scheme, in which a combination of certificate less public key cryptography (CL-PKC) and threshold cryptography is employed.The scheme proposed in this paper not only achieves several enhanced security attributes for key management in MANET but also eliminates the need for certificate-based public key distribution and the key escrow problem efficiently. .
