摘要： Vehicular Cloud Computing (VCC) is a contemporary paradigm that includes the Internet of Things (IoT), cloud computing, and vehicular networking technologies. VCC offers vehicle-to-device, vehicle-to-infrastructure, and vehicle-to-vehicle communication in which the vehicles can communicate using sensing abilities. VCC is exploiting the IoT environment, cloud architecture, and vehicle resources. However, the energy-efficient privacy of communicators and security of communication are assertive problems in VCC. To accomplish this goal, we present an identity-based authentication scheme for VCC which also uses radio frequency identification (RFID). The security and robustness of the devised scheme are evaluated using informal and formal analysis. The informal analysis shows that our scheme is vigorous to resist various attacks. The formal analysis is done through Random Oracle Model (ROM) which shows that the scheme is secure and efficient. The performance of our scheme is also determined and compared with various related schemes which clearly illustrate the efficiency of the proposed scheme. Thus, our scheme is very efficient for employment in the VCC environment.

摘要： Internet of Things (IoT) technologies rapidly evolve and are used in many real-life applications. One of the core technologies used in various IoT applications is Radio Frequency IDentification (RFID) technology. RFID wirelessly and uniquely identifies the tagged objects without a direct line of sight. However, the research community had reported privacy and security-related concerns in RFID systems, where an adversary may tamper, eavesdrop, add, delete, or even modify the transmitted messages over an insecure communication *** address the issues mentioned above, we propose an Efficient, Secure, and practical ultra-lightweight RFID Authentication Scheme (ESRAS), which uses rank operation for low-cost tags. We utilize a simplistic bitwise exclusive-OR, circular left rotation, and a newly proposed ultra-lightweight rank operation to provide high security at low cost. The analysis of ESRAS concerning its security and performance shows that it effectively resists several known attacks and is relatively superior to the existing schemes regarding the computational and storage costs. Moreover, ESRAS shows more suitability for low-cost RFID tags and can be executed in a multimedia big data environment.

摘要： In RFID systems, the privacy problem has attracted increasing attention as the tags have extremely limited on-chip resources and may blindly respond to unauthorized readers. To protect the privacy, one widely used solution is to deploy one or more blocker tags to collide the RF signal sent from protected tags all the time. In this paper, we investigate the problem of tag identification in privacy-sensitive RFID systems when we have the authorized reader(s). Due to the presence of blocker tags, the tag identification becomes more challenging since the protected tags and blocker tags will always respond concurrently, leading to unreconciled collisions. To overcome this challenge, we in this paper propose three efficient tag identification protocols IIP, SIP, and SUIP, which meet three application requirements: privacy, accuracy, and efficiency. IIP iteratively deactivates blocking tags as well as labeling genuine tags, and finally identifies tags by avoiding all the unreconciled collisions. On top of IIP, SIP further avoids the slot waste by carrying out a filter to separate genuine tags from others in advance. Furthermore, SUIP can identify the incremental unknown tags in an efficient way. It separates the incremental unknown tags from others by using a filter with improved performance and puts forward a collision reconciliation technique to accelerate the identification process. Simulation results demonstrate that our protocols are able to guarantee any identification accuracy in a privacy-protected way.
