Privacy protection of warning message publishing protocol in VANET by Hui LIU, Xinyan LIU, Yan XU, Hong ZHONG, Meng WANG

“…Aiming at the problem that the traffic control department publishes violation messages to vehicles, a privacy protection warning message publishing protocol was proposed, where transportation manage department could obtain vehicle’s pseudonym according to its real identity and send warning message to vehicles based on its pseudonym in VANET.Elliptic curve cryptography was used to construct a lightweight warning message publishing and receiving process.Furthermore, the conditional privacy protection was realized, which could effectively protect the identity privacy of the receiving vehicle.Security analysis shows that the proposed protocol can meet the security requirements of VANET.Performance analysis shows that the protocol protocol has lower computational overhead and communication overhead.…”

Ring-based efficient batch authentication and group key agreement protocol with anonymity in Internet of vehicles by Haibo ZHANG, Kai LAN, Zhou CHEN, Ruyan WANG, Can ZOU, Mingyue WANG

“…Aiming at the problem that the current batch authentication and key agreement protocol were relied on semi-trusted road side unit (RSU) and were not suitable for key update in large-scale Internet of vehicles (IoV), a ring-based efficient batch authentication and group key agreement protocol with anonymity in IoV was proposed.The anonymity was ensured by the pseudonym mechanism.The authentication key pairs were constructed by the chaotic map, and the batch authentication for many vehicles was quickly completed by a small number of bilinear maps.The joining and leaving of vehicles in large-scale IoV scenario were fully considered, a ring session group was efficiently constructed by using the semi-group property of chaotic maps, and a group key establishment and update mechanism suitable for large-scale vehicles was designed.In addition, a pseudonym update mechanism and an anonymous tracing mechanism were designed to ensure a more secure session process.At the same time, the BAN logic model was used to prove the semantic security of the protocol.The security analysis and simulation results show that the proposed protocol has multiple security attributes and certain efficiency advantages.…”

Anonymous trust management scheme of VANET based on attribute signature by Min XIAO, Faying MAO, Yonghong HUANG, Yunfei CAO

“…Trust management mechanisms can solve the authenticity assessment problem of messages and establish trust between communication entities in the VANET.However, current trust management schemes lack an effective privacy protection mechanism, leading to privacy concerns for vehicles when binding their identity with their trust level.Based on the anonymity of attribute-based signature, an anonymous trust management scheme was proposed for VANET.The trust level of the vehicle was maintained by the trusted authority.The trust level of vehicles and the current time were taken as the attribute identity set of the vehicle, so as to realize the binding of the anonymous vehicle identity with its trust level, which could provide the privacy protection of vehicles.In addition, the timely update of attribute signature private key could resist false reputation attack and the trust level of the vehicle could be verified anonymously while the attribute signature was verified.Furthermore, the pseudonym was used to hide the real identity of the vehicle, enabling only the trusted authority could parse the real identity of vehicles from the pseudonym to update their trust level, and providing legal and secure tracking of the malicious vehicle identity vehicle.Under the general group model, the attribute-based signature scheme is proven to satisfy the security of unforgerability.The security analysis further shows that the scheme protects the identity and location privacy of vehicles, enables only the trusted authority to legally track malicious vehicles, resists false reputation attacks, ensures communication integrity, and resists replay attacks.Performance analysis confirms that the proposed scheme has better computation and communication efficiency than existing schemes.…”

Marcello Drutel (1897-1985) : figure féminine d’une écriture érotique by Jean-Yves Casanova, Cécile Noilhan

“…Marcelle Drutel (1897-1985), a provencal poetess of the first half of the 20th century, gave a start to her career as a writer with the publication of a collection of poems, Li Desiranço, published in 1933 with the pseudonym « l’Aubanelenco ». These first love poems contrast with the traditional values of this period, yet they are also part of a literary tradition that began with the poetesses of Antiquity and theTrobairitz. …”

Secure communication mechanism for VSN based on certificateless signcryption by Wenbo ZHANG, Wenhua HUANG, Jingyu FENG

“…To solve the communication security problems of vehicular social network (VSN), an efficient certificateless signcryption scheme was proposed.The proposed scheme was proven secure in the random oracle model based on the computational Diffie-Hellman problem and elliptic curve discrete logarithm problem, which provided confidentiality and unforgeability protection for VSN members.In addition, when the pseudonym mechanism was used to solve the privacy protection problem in VSN, without installing tamper-proof device, a self-generation mechanism for vehicle pseudonyms and their keys was proposed.The performance analysis shows that the proposed scheme can decrease communication cost, and significantly reduce the computation overhead of the key generation center.…”

Research on protection technology for location privacy in VANET by Jian-ming ZHANG, Yu-juan ZHAO, Hao-bin JIANG, Xue-dan JIA, Liang-min WANG

“…Location-based services in VANET solved the problem of road safety,and provided the convenient services to drivers and passengers.But it also brought new problems of privacy protection.The content of privacy protection was analyzed,and put emphasis on two kinds of privacy protection technology based on pseudonyms and signature respectively.Pseudonym-based schemes were classified as special-area based,silence-period,cryptographic mix-zones and mix-zones communication proxy based schemes.Signature-based schemes were also divided into two classes:group-signature and ring-signature.The evaluation methods for privacy protection level were surveyed,in which anonymity set,entropy metric,mathematical analysis theory and formal analysis were discussed and compared.…”

Une balle blanche dans un roman noir by Sophie Vallas

“…In 1982 Paul Auster published a roman noir entitled Squeeze Play under the pseudonym of Paul Benjamin. The novel is also a “baseball novel”: its plot essentially deals with a baseball New York team and its former, fallen star, and the final resolution of the mystery intervenes thanks to a revelation brought by a baseball game in which a rather rare and spectacular maneuver (the double suicide squeeze) is used by one of the teams to turn the tables and win the game. …”

Intra-group mutual authentication key agreement protocol based on Chinese remainder theorem in VANET system by Haibo ZHANG, Zhou CHEN, Hongwu HUANG, Xiaofan HE

“…Aiming at the problem that vehicles in the vehicular ad-hoc network (VANET) system were vulnerable to malicious attacks when communicating with each other on the public network, a mutual authentication key agreement protocol in the VANET was proposed.A dynamic vehicle group was established by the Chinese remainder theorem to adapt to the rapid changes in the VANET topology.Signature information was used by both parties in communication to quickly authenticate the identity of the message sender, and key agreement was conduct through the semigroup of Chebyshev chaotic mapping.The pseudonym update and private key update mechanism were adopted to protect the privacy and security of the vehicle’s identity.The identities of malicious vehicles were tracked accurately by using signature information, and were revoked quickly by modifying the public key information.In addition, the semantic security of the protocol was proved by the BAN logic model.The simulation results show that the proposed protocol can effectively reduce the communication consumption and significantly reduce the computational consumption compared with the existing similar literature.…”
