In this paper, we present a detailed analytical model based on a kind of simplest scheme, called Random Changing Pseudonyms (RCP), to quantify the level of location privacy provided by this scheme. Furthermore, according to the proposed model, we analyze and compare two special distributions, i.e., uniform discrete and age-based distributions. The results show that RCP scheme with uniform discrete distribution is better than with age-based distribution on protecting location privacy in VANETs. The accuracy of this model is verified by a set of simulations.","PeriodicalId":215517,"journal":{"name":"2011 International Conference on Network Computing and Information Security","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121073453","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 this paper, based on the identity-based encryption scheme proposed by Gentry recently, we present a direct construction of an identity-based blind signature scheme. Our identity-based blind signature scheme is computationally efficient and the signature is short. We prove that our scheme is concurrently secure with a tight security reduction in the standard model assuming that the $q$-SDH problem is hard.","PeriodicalId":215517,"journal":{"name":"2011 International Conference on Network Computing and Information Security","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114079865","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}

It achieves optimal efficiency in terms of the number of rounds and the total number of exchanged messages for the case that the receiver's choice is unconditionally secure. The computation time of the 1-out-2 oblivious transfer scheme is very efficient, too. The receiver need compute 4 modular exponentiations only, and the sender need compute 8 modular exponentiations. The new construction is secure if the EDDH assumption holds. Since EDDH assumption is weaker than DDH assumption for generic bilinear groups, the new scheme is a good replacement for Wen-Guey Tzeng's oblivious transfer schemes when bilinear group is adopted as construction platform.","PeriodicalId":215517,"journal":{"name":"2011 International Conference on Network Computing and Information Security","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122467623","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}

First sub problem is to find the routes on which the data transfers occur. Second sub problem is to determine the amount of flow to be committed on each route.

It is a large network with characteristics of high exposure, dynamic topology, heterogeneous network, etc. The requirement of security for group communications system is much stronger. A group key management scheme based on the hierarchical and domain structure of Near-Space Network is proposed. The proxy re-cryptography algorithm is used in the rekeying process, which solves the problem of a single point of failure thoroughly. Rekeying algorithm for group members' switching between domains is designed and can efficaciously reduce the rekeying overhead caused by switch actions of high speed nodes.
