“…Especially due to the fact that UHF RFID allows ranges of more than 10 meters, the security of the transmitted data is even more crucial than with near field communication systems. Possible implementations of encryption for RFID have already been shown several times [8,9,10]. The problem with UHF RFID is the low energy available at the passive transponder [11].…”

Ultra high frequency radio frequency identification (UHF RFID) is becoming a key technology in the Internet of Things. It allows the implementation of batteryless and wireless nodes, including sensors and actuators. Due to its possible transmission range of >10 m and potential to carry critical information, security is a highly important topic. For this reason, the International Organization for Standardization has published several crypto suites for UHF RFID within the ISO-29167 standard in 2014. Recently, research has focused on implementing those encryption features on the transponder side. However, currently no crypto enabled UHF RFID readers are available. In order to cope with the rapid development in this field, ‘open’ and flexible readers based on software defined radios are needed. They make it possible to quickly adapt the protocol and to test new functionalities such as encryption. This paper deals with the first implementation of the ISO 29167-19 standardized RAMON decryption on a software defined radio. The programming of this hardware is done in LabVIEW which allows for controlling the built-in transceiver modules. However, first measurements show that the decryption takes 51 s. This is because LabVIEW is not suitable for handling very large numbers like they are utilized in cryptography. Because such a long processing time is not feasible in experiments nor in a real-life scenarios, this method is not suitable for a prototyping platform. Thus, a different approach is chosen to optimize the decryption processing time. LabVIEW still provides the framework for handling the protocol and controlling the transceivers, but the decryption is performed in a Java application. In that way, the entire decryption process takes only about 2.2 ms, which is 23,318 times faster than the implementation in LabVIEW. Thus, this new approach meets the necessary timing requirements and is suitable for realistic application scenarios. The shown method allows development and testing of new functionalities in UHF RFID systems but may also be employed in any application that require long processing times in LabVIEW. Furthermore, the implementation of decryption features is the first necessary step towards a fully compliant, crypto enabled interrogator for UHF RFID, featuring a high adaptability.

The limitation of RFID tag resources plays a great challenge for the researchers to implement an applied RFID scheme which is privacy-preserving, efficient and suitable for a lowcost tag. In this paper, we suggest a privacy-preserving mutual authenticated key establishment protocol for RFID systems with no computational or storage consumption. Our scheme is based on the utilization of the fading channel features and the use of Physically Unclonable Functions (PUFs). Firstly, we exploit the resources provided by the time-varying channel gains to share a common randomization source between RFID reader and its tags, for key establishment. Secondly, we use PUF for tags authentication and improving the key generation rate of our suggested protocol. We determine the upper bound for the generation rate of a secret key shared among reader and tag, and give numerical examples to reveal the performance of our suggested technique.

Various distributed ledger technologies (DLTs), such as blockchain, have evolved significantly in recent years. These technologies provide a robust and effective solution for providing confidentiality, integrity, nonrepudiation, authentication, and transparency. While blockchain has many advantages, it has various limitations as well, such as complexity, low throughput, privacy, and so on. We discuss the issues that must be considered when deciding whether to use these technologies in a given case or not. We describe the operation of blockchain, application areas where blockchain is suitable, and those where it is not. We also discuss the applicability of other emerging DLTs, apart from blockchain technology, such as Hashgraph, Zcash, Nano coin, and IOTA. INTRODUCTIONAs the name suggests, a blockchain can be considered as a database where digital information (ie, "Blocks") is stored in a distributed network as a chain of blocks. Blockchain falls in the class of distributed ledger technologies (DLT) that allow a database to be used and maintained in a distributed manner. Blockchain provides a shared ledger of transactions 1 that can be read, verified and stored in the form of blocks, forming a chain-like structure. Depending on the size of the transaction, a block may store up to a few thousand transactions (eg, a single block in the bitcoin blockchain can store about 1 MB of data). The security and anonymity provided by blockchain relies on the use of public key based digital signatures, hash functions, and the distributed nature of the database. Participants in a blockchain are connected through a peer-to-peer (P2P) network and are independent of each other. 2 This architecture allows the sharing of resources, 3 avoids single point of failure, and reduces the likelihood of data tampering because the data is not stored or managed by specific nodes. [4][5][6] However, there are many challenges 7 that need to be resolved in the case of distributed networks. These challenges include accountability, confidentiality, integrity, nonrepudiation, and authentication, due to the absence of any central authority. Another major issue is trust because there is no central authority that can resolve any ambiguities or disagreements that may occur. Blockchain resolves all these issues. Confidentiality and authentication are ensured using two-way encryption, that is, by encrypting the data first by the sender's private key and then by the receiver's public key. To decrypt it, first the receiver's private key is used and then the sender's public key. Consequently, data remains confidential, integrity is achieved and because the data can be obtained using sender's public key, it acts as a digital signature that authenticates the data and eliminates the possibility of nonrepudiation. Trust is obtained by introducing a consensus Trans Emerging Tel Tech.
