Fully Self-organized Key Management Scheme In MANET And Its Applications

摘要

The paper first proposes a fully self-organized key management scheme in mobile ad hoc networks which is both certificateless and free from any trusted third party such as Certificate Authority or Key Generation Center. The scheme allows a node to set up the public/private key pair all by itself and use the public key as its identity according to the property of ad hoc networks. Based on the scheme, some applications such as Encryption, Signature, Signcryption algorithms are given. Among these algorithms, the security of encryption algorithms is detailed and the AdvancedEnc is proved to be IND-CCA secure encryption algorithm under the random oracle model. These applications show that our key management scheme is self-organized, simple, efficient and practical.
