In mobile ad hoc networks, one challenge in certificate revocation design is to revoke malicious nodes' certificates accurately. In this paper, we build up on our previously proposed scheme [1], which enables the recovery of falsely accused nodes' certificates. This scheme is a cluster-based certificate revocation scheme that divides the network into clusters of one cluster head and cluster members...
As a kind of mobile data service, mobile payment service has approached people's lives. It becomes the focus and will be a field where telecom service providers compete. After analyzing the current mobile payment service in China, this paper puts forward an optimization design of the GPRS mobile payment system based on radio frequency identification (RFID) as a transitional solution before the prevalence...
This paper studies key management, a fundamental problem in securing mobile ad hoc networks (MANETs). We present IKM, an ID-based key management scheme as a novel combination of ID-based and threshold cryptography. IKM is a certificateless solution in that public keys of mobile nodes are directly derivable from their known IDs plus some common information. It thus eliminates the need for certificate-based...
