In terms of security, a public/private key infrastructure scheme is used along with a symmetric cryptographic mechanism. Public key cryptography is used to encrypt the communication between the peers, while symmetric cryptography is used primarily for authentication purposes. The public/private key pair of each peer is periodically refreshed to further improve the security level of the system. Two schemes are proposed: the Hierarchical RELOAD (HR), where the Bootstrap peers are central to all the operations implemented within the protocol, and the Semi-Hierarchical RELOAD (SHR) that follows the same logic with HR but also permits, for a limited time window, a more distributed operation for the protocol. We evaluate the proposed protocols in comparison to RELOAD, and the results show that HR produces considerably lower communication overhead within the peer-to-peer network than both RELOAD and SHR, with the latter's however more flexible network operation justifying the additional cost.","PeriodicalId":369459,"journal":{"name":"Q2S and Security for Wireless and Mobile Networks","volume":"198 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116502299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SEGURA employs probabilistic set membership constructs to amortize the cryptographic functionality of traditional authentication mechanisms such as Message Authentication Codes, Hash trees, authentication graphs, and digital signatures in relatively small sized data structures. Using probabilistic set membership constructs in the integrity verification process eliminates any form of dependency among individual network packets which gives the security protocol the capability of handling out of order packets and enduring high packet loss rates. This makes SEGURA a very suitable choice for operation in performance-challenged DTNs with highly disruptive natures featuring excessive disconnection rates, massive delays, and intermittent communication. Moreover, the SEGURA integrity enforcement mechanism gives intermediate DTN routers and gateways the ability to verify the integrity of bundles without employing expensive public-key operations. The goal here is to isolate the effects of any malicious attack as close as possible to the source of the attack. This results in the reduction of bogus network traffic and hence contributes to a major decrease in the messaging delay caused by distant packet retransmission.","PeriodicalId":369459,"journal":{"name":"Q2S and Security for Wireless and Mobile Networks","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123466198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, the open and shared nature of wireless networks also causes a number of security concerns. In particular, data confidentiality is one of the most important issues. As usual, cryptosystems are adopted to protect the data confidentiality and integrity, including symmetric and asymmetric encryption algorithms. However, due to the limitations of these algorithms, how to apply them to wireless and mobile networks is always a debatable topic. In this paper, we explore the issue of applying both symmetric and asymmetric key algorithms for data encryption and authentication. Then we propose an advisable solution for the application of these cryptographic algorithms, which not only takes advantage of symmetric key to provide the effective protection of data transmission, but also employs asymmetric key to authenticate a node reliably. We formalize the security analysis and show that our system owns effective and provable secure attributes based on rational combination of classic encryption algorithms. Thus, we avoid the weakness of these two cryptosystems and make use of their advantages to establish a secure environment, by the combination of symmetric and asymmetric key algorithms.","PeriodicalId":369459,"journal":{"name":"Q2S and Security for Wireless and Mobile Networks","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121036989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the proposal, the class-based queueing with the priority queue (PQ) scheduler is exploited in network layer at the access point (AP), and real-time applications are given the highest priority. In order to regulate the best effort traffic sent from wireless stations, we apply the MAC-frame Receive Opportunity Control (ROC), in which the AP intentionally does not return the ACK frame with a given probability when receiving a data frame of best effort traffic from a wireless station. By the intentional failure in acknowledging the receipt of frames, the ROC can control the packet sending rate on a per-station basis. The class-based queueing in network layer and the ROC in MAC layer are jointly utilized with the TCP window control in transport layer to provide the QoS guarantee for bidirectional real-time applications. The proposed cross-layer approach requires only the upgrade of the hardware (or software) of the AP, which is an important advantage over existing proposals on the QoS support in WLANs. The extensive simulation experiments reveal that, when best-effort TCP flows compete with voice conversations (VCs) in a WLAN, the proposed cross-layer approach provides better QoS to VCs than IEEE802.11e and, when best-effort UDP flows compete with VCs, the proposed approach and IEEE802.11e provides the same level of QoS to VCs.","PeriodicalId":369459,"journal":{"name":"Q2S and Security for Wireless and Mobile Networks","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125564110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
