The increasing daily use of virtual currency (cryptocurrency) is being adopted worldwide for many legal and illegal transactions. Cryptocurrency technology operates on a network that allows people to make payments around the world without any middleman. Since the technology was first developed, it became popular, and the price of cryptocurrencies started to rise and became unstable. In terms of the returns gained from investing in cryptocurrencies, they have been huge in recent times, but there has always been a question about their existence and reliability. A cryptocurrency is a digital process that relies on the use of an encryption system for security primarily. Despite the challenges and problems facing cryptocurrencies, the success of Bitcoin has led several companies to search for alternative digital currencies. This paper tries to compare two cryptocurrencies - Bitcoin (BTC) and Litecoin (LTC) with respect to their stability and understanding its trends in the recent period.

Internet of Vehicles (IoV) is a multinode network that exchanges information in an open, wireless environment. Variouscommunication activities exist between IoV entities to share important information such as (ID, location, speed, messages, andtraffic information), necessary for network operation. As part of intelligent transportation, IoV is considered a hot subject forresearchers, because it is still facing many unresolved challenges, especially those concerning security and privacy. )e variation ofsecurity-privacy threats that can menace the safety, privacy, and lives of vehicle occupants makes security the leading point ofinterest. )e development of communication protocols for autonomous vehicles opens to us new issues to study and enhance theperformance of IoV networks in terms of security and privacy. Several works have been reported, proposing many solutions forpractical security challenges including a considerable number of survey-review papers published in respectable channels. )emain motive of this review paper is to present the latest developments related to IoV security, as well as to address existinglimitations. )e high frequency of publication on IoV architecture, security, and new solutions leads us to write a compact,comprehensive, and up-to-date review. Inclusion criteria for selected papers include recent publications, number of citations, andimpact of the research. In the present survey paper, the IoV architecture model is defined with all related communication types,and security and privacy issues are analyzed and presented with recently proposed solutions in a clear method. Clear classificationsof threats, attacks, protocols, and solutions are presented. Moreover, the use of blockchain-based IoV to improve system security isdiscussed highlighting the most important trends and taxonomies. )e paper was written to be a candidate as the first to read onthe topic of the IoV security challenge, presenting problems and solutions in a clear, smooth, complete, and integrated manner.

The Internet of Vehicles (IoV) is a network that connects vehicles and their environment: in-built devices, pedestrians, and infrastructure through the Internet using heterogeneous access technologies. During communication between vehicles, roadside units, and control rooms, data confidentiality and privacy are critical issues that require effective measures. Several works have been proposed for securing IoV environments based on vehicles-to-infrastructure authentication; However, some schemes have security vulnerabilities, while others have shown efficiency issues. Due to its decentralization, stability, and transaction tracking capabilities, Blockchain as an emerging technology presents a potential solution for IoV security. This article provides an in-depth examination of the benefits of blockchain for a 5G-based IoV environment. In particular, we propose and evaluate a novel blockchain-based secure data exchange (BSDCE-IoV) scheme based on Elliptic Curve Cryptography algorithm. Our solution is designed to eliminate several potential attacks that pose a threat to the IoV environment. Deep examination using the Real-or-Random oracle model and Scyther tool, in addition to the informal security analysis, validates the scheme regarding security and privacy. The Multi-precision Integer and Rational Arithmetic Cryptographic Library (MIRACL) assesses the computational and communication overhead. Computational and communicative overheads were also evaluated using the Multi-precision Integer and Rational Arithmetic Cryptographic Library (MIRACL). BSDCE-IoV shows higher performance in terms of security, functionality, and time delay than a number of recent selective work in IoV security.
