Secure Key Management Protocol in WIMAX

Secure Key Management Protocol in the Wireless Sensor Network

To achieve security in wireless sensor networks (WSN), it is important to be able to encrypt messages sent among sensor nodes. We propose a new cryptographic key management protocol, which is based on the clustering scheme but does not depend on the probabilistic key. The protocol can increase the efficiency to manage keys since, before distributing the keys by bootstrap, the use of public keys...

Key Management in Mobile WiMAX Networks

Secure Authenticated Key Exchange Protocol

From Seo and Sweeney proposed SAKA (Simple Authenticated Key agreement Algorithm), many SAKA variants were proposed to cope with the weaknesses in SAKA. However, they still are vulnerable to off-line password guessing attack. This paper proposes a new secure authenticated key exchange protocol that can resist off-line password guessing attack. To solve the vulnerability of former protocols, key...

Provably secure and efficient identity-based key agreement protocol for independent PKGs using ECC

Key agreement protocols are essential for secure communications in open and distributed environments. Recently, identity-based key agreement protocols have been increasingly researched because of the simplicity of public key management. The basic idea behind an identity-based cryptosystem is that a public key is the identity (an arbitrary string) of a user, and the corresponding private key is ...

Secure Multicast in WiMAX

Multicast enables efficient large-scale content distribution and has become more and more popular in network service. Security is a critical issue for multicast because many applications require access control and privacy. This issue is more sensitive to wireless network, which is lack of physical boundaries. IEEE 802.16 is the standard for next generation wireless network, which aims to provid...
