“…With Rabin's scheme, an authenticated key agreement scheme can be developed such that the cryptographic burden can be properly allocated across the network entities in WLANs or WMSNs. The PPAB architecture is designed based on Rabin's public key cryptosystem, which aims at greatly reducing the computational overhead in the MU side at the expense of putting more load on the AP [13].…”

“…The U-token is an untraceable, refundable, and double-spending-protected electronic currency, which can be purchased by the MUs from the RB and can serve as authentication credential and a payment method for the MUs to gain access to multiple WISP domains in the WMSNs. The U-token can preserve privacy of MUs through the partially blind digital signature technique, which is a cryptographic tool introduced in [13]. The WISPs can claim their credits by performing offline clearance operations.…”

Abstract-Wireless metropolitan area sharing networks (WMSNs) are wide-area wireless networks with nodes owned and managed by independent wireless Internet service providers (WISPs). To support seamless roaming in emerging WMSNs, in this paper, we propose a localized and distributed authentication and billing architecture that aims at enabling efficient and privacy-preserving mutual authentication between mobile users (MUs) and WISPs. User anonymity and identity privacy can be protected, even in the presence of collusion between WISPs and a roaming broker (RB), which is considered to be the strongest user privacy protection. An efficient billing architecture is introduced and performed in the same stage of roaming, where U-tokens are defined and can be purchased by MUs from an RB as authentication credentials for the MUs to access the wireless network. The WISPs, thus, can cash the collected U-tokens in the RB for payment. We show that the proposed authentication and billing architecture can support localized inter-WISP authentication through the divisible blind signature scheme and a local witness strategy. A detailed analysis on a number of performance metrics, such as computation time and power consumption, is given to validate the performance of the proposed architectures.Index Terms-Billing, partially blind signature, privacy protection, roaming, wireless metropolitan area sharing networks (WMSNs).

“…Since the digital signature can provide the authenticity, integrity and non-repudiation, hence, along with practical applications' requirements, the special digital signatures have been widely proposed. These mainly include: proxy signatures [38,39] , blind signatures [40][41][42] , encryption verifiable signatures [43] , undeniable signatures [44,45] , forward secure signatures [46,47] , key isolation signatures [48] , online/offline signature [49] , threshold signatures [41,[50][51][52] , aggregation signatures [53] , ring signatures [53,54] , designated verifier signatures [55,56] , confirmed signatures [57] , and their variants [58] .…”

The 21st century is the age of information when information becomes an important strategic resource. The information obtaining, processing and security guarantee capability are playing critical roles in comprehensive national power, and information security is related to the national security and social stability. Therefore, we should take measures to ensure the information security of our country. In recent years, momentous accomplishments have been obtained with the rapid development of information security technology. There are extensive theories about information security and technology. However, due to the limitation of length, this article mainly focuses on the research and development of cryptology, trusted computing, security of network, and information hiding, etc.information security, cryptology, trusted computing, network security, information hiding

“…To thwart various attacks due to compromised MAPs, we adopt a local voting strategy and the threshold digital signature mechanism to enhance the overall security assurance [11]. With the local voting strategy, the Dcoin is issued under the endorsement of not only the serving MAP (sMAP), but also its neighboring MAPs (nMAPs), instead of by any single MAP.…”

Abstract-The future metropolitan-area wireless mesh networks (WMNs) are expected to contain compromise-prone Mesh Access Points (MAPs) with a high frequency of inter-domain roaming/handoff events. This paper introduces a novel secure localized authentication and billing (SLAB) scheme, which aims to address both security guarantee and performance in terms of system compromise resilience capability, inter-domain handoff authentication latency, and workload of the roaming broker (RB). With extensive analysis and simulation, we demonstrate that the proposed scheme can be a practical solution for achieving secure roaming and billing in metropolitan-area WMNs.Index Terms-Wireless mesh networks, security, inter-domain handoff, authentication and billing.
