The security issues in ad hoc network are increasingly important. In this paper, we propose a distributed key management what approach by using braid groups and key tree. Without any assumption of prefixed trust relationship between nodes, the proposed method works in a self-organizing way to provide the key management services. The using of the proposed(More)
Broadcast encryption is the scheme that a sender encrypts messages for a designated group of receivers, and sends the ciphertexts by broadcast over the networks. Many research papers have done it using elliptic curve cryptography. In this paper, we propose the broadcast encryption scheme based on braid groups cryptography which is an alternative method in(More)
