A Secure Distributed Authentication Scheme Based on CRT-VSS and Trusted Computing in MANET

With the rapid development of Mobile ad hoc network (MANET), secure and practical authentication is becoming increasingly important. There still exist several unsolved problems. It may suffer from cheating problems and Denial of services (DoS) attacks towards authentication service. Most existing schemes do not have satisfactory efficiency due to the exponential arithmetic complexity of Shamir's scheme. We explore the property of Verifiable secret sharing (VSS) schemes with Chinese remainder theorem (CRT), then propose a secret key distributed storage scheme based on CRT-VSS and trusted computing techniques. We discuss the homomorphism property of CRT-VSS and design a secure distributed Elliptic curve-digital signature standard (ECCDSS) authentication scheme. We provide formal guarantees towards the scheme proposed in this paper.
