Key Management for Wireless Interworking

Key Management Protocol for Roaming in Wireless Interworking System

3GPP makes efforts to enable usage of 3GPP system functionalities such as SIP calls between mobile terminals and 3GPP systems via the WLAN and to utilize 3GPP system functionalities to complement the functionalities such as charging means, authentication, authorization, and accounting functions available in the WLAN. And an interworking framework to integrate the services of 3G, WLAN and WiBro ...

Hypercube Bivariate-Based Key Management for Wireless Sensor Networks

Wireless sensor networks are composed of very small devices, called sensor nodes,for numerous applications in the environment. In adversarial environments, the securitybecomes a crucial issue in wireless sensor networks (WSNs). There are various securityservices in WSNs such as key management, authentication, and pairwise keyestablishment. Due to some limitations on sensor nodes, the previous k...

Toward an energy efficient PKC-based key management system for wireless sensor networks

Due to wireless nature and hostile environment, providing of security is a critical and vital task in wireless sensor networks (WSNs). It is known that key management is an integral part of a secure network. Unfortunately, in most of the previous methods, security is compromised in favor of reducing energy consumption. Consequently, they lack perfect resilience and are not fit for applications ...

Wireless ATM: Interworking Aspects

Key management for wireless ad hoc networks

Key management is a fundamental security service to enable secure wireless ad hoc networks (WAHN). To date existing key management solutions based on either public key infrastructures (PKI) or key pre-distribution scheme (KPS) exhibit limitations for WAHNs. We firstly develop the Hybrid Key Management Infrastructure (HKMI) for WAHNs composed of moderate-resource devices. The HKMI complements PK...
