H.264/AVC is a widespread standard for high definition video (HD) for example DVD and HD videos on the internet. To prevent unauthorized modifications, video authentication can be used. In this paper, we present a cryptanalysis of a H.264/AVC video authentication scheme proposed by Saadi et al. [1] at EUSIPCO 2009. Our result will prevent situations where newer schemes are developed from the scheme thus amplifying the flaw. The designers claimed that the scheme can detect modifications on watermarked video. However, we show that an attacker can modify the watermarked video and compute a valid watermark such that the recipient will retrieve a watermark from the modified watermarked video that will match what the recipient computes during video authentication check. Thus, the recipient will think the tampered video is authentic. The first main problem of the scheme is its use of hash functions for watermark generation. Since hash functions are public functions not depending on any secret, the attacker can modify the watermarked video and feed this through the hash function to compute a new watermark. The second problem is that it is possible for the attacker to perform watermark embedding thus producing a modified watermarked video. On receiving the modified video, the recipient recomputes the watermark and compares this with the watermark extracted from the video. They will match because the embedded watermark and recomputed watermark use the same hash function based watermark generation and the same input i.e. the modified video. Our cryptanalysis strategy applies to any watermarking based video authentication scheme where the watermark and embedding are not functions of secrets. As countermeasure, the functions should be designed so that only legitimate parties can perform them. We present two improved schemes that solve this problem based on private key signing functions and message authentication functions respectively.

Radio frequency identification (RFID) is a kind of non-contact automatic identification technology. The Internet of Vehicles (IoV) is a derivative of the Internet of Things (IoT), and RFID technology has become one of the key technologies of IoV. Due to the open wireless communication environment in RFID system, the RFID system is easy to be exposed to various malicious attacks, which may result in privacy disclosure. The provision of privacy protection for users is a prerequisite for the wide acceptance of the IoV. In this paper, we discuss the privacy problem of the RFID system in the IoV and present a lightweight RFID authentication scheme based on permutation matrix encryption, which can resist some typical attacks and ensure the user’s personal privacy and location privacy. The fast certification speed of the scheme and the low cost of the tag is in line with the high-speed certification requirement in the Internet of vehicles. In this thesis, the specific application scenarios of the proposed RFID authentication scheme in the IoV is also discussed.

It had been predicted that by 2020, nearly 26 billion devices would be connected to the Internet, with a big percentage being vehicles. The Internet of Vehicles (IoVa) is a concept that refers to the connection and cooperation of smart vehicles and devices in a network through the generation, transmission, and processing of data that aims at improving traffic congestion, travel time, and comfort, all the while reducing pollution and accidents. However, this transmission of sensitive data (e.g., location) needs to occur with defined security properties to safeguard vehicles and their drivers since attackers could use this data. Blockchain is a fairly recent technology that guarantees trust between nodes through cryptography mechanisms and consensus protocols in distributed, untrustful environments, like IoV networks. Much research has been done in implementing the former in the latter to impressive results, as Blockchain can cover and offer solutions to many IoV problems. However, these implementations have to deal with the challenge of IoV node’s resource constraints since they do not suffice for the computational and energy requirements of traditional Blockchain systems, which is one of the biggest limitations of Blockchain implementations in IoV. Finally, these two technologies can be used to build the foundations for smart cities, enabling new application models and better results for end-users.
