Authenticated key exchange protocol for medical sensor network
Pla Information · 2010
The unique set of security requirements for a medical care system based on wireless sensor network is identified,and an ideal functionality of authenticated key exchange for medical sensor network is defined in the universal composability model.The ideal functionality guarantees strong security and availability properties.A universally composable security authenticated key exchange protocol NB-AKE is proposed to set up shared keys between sensor nodes and base stations.The implementation of NB-AKE protocol requires the use of pseudo-random function.NB-AKE protocol provides anonymous authentication,and it is of forward security and concurrent security.The new protocol has simpler structure,lower communication overhead,and lower computational burden on nodes.
