“…From the perspective of system design, a blockchain must contain a consensus protocol to address the issue of agreement among trustless nodes. Because the decentralized blockchain architecture is well-suited to original distributed network designs, it has also attracted considerable attention for its potential to fulfill a wide variety of functions (tasking [10] and key management [11]) inspiring promising blockchain projects such as XRP [12], ETH [13], and Cosmos [14]. In general, blockchains are decentralized, shared ledgers with tamperproof, nonforgeable, and traceable characteristics.…”

Authentication and authorization (A & A) mechanisms are critical to the security of Internet of Things (IoT) applications. Smart grid system processing and exchanging data without human intervention, known as smart grids, are well-known as IoT scenarios. Entities in such smart grid systems need to identify and validate one another and ensure the integrity of data exchange mechanisms. However, at present, most commonly used A & A protocols are centralized, resulting in security risks such as information leaks, illegal access, and identity theft. In this study, we propose a new distributed A & A protocol for smart grid networks based on blockchain technology to address with these risks. The proposed protocol integrates the decentralized authentication and immutable ledger characteristics of blockchain architectures suitable for power systems with a novel blockchain technique to realize both identity authentication and resource authorization for smart grid systems. We discuss the security of and threat models for prior A & A protocols and demonstrate how our protocol protects against these threats. We further demonstrate an approach to a real deployment of our A & A protocol using the FISCO consortium platform, applying algorithms from smart contract systems. Finally, we present the results of experimental simulations showing the efficacy and efficiency of our proposed protocol.

“…Moreover, attribute revocation is also an intractable problem in CP-ABE and requires extra computation and communication costs to deal with. With this in mind, many researchers study the issue of data sharing in IoT with a different primitive: group key management [5,6]. However, traditional group key management shows poor flexibility and scalability for multigroup access control.…”

Hierarchical key assignment scheme is an efficient cryptographic method for hierarchical access control, in which the encryption keys of lower classes can be derived by the higher classes. Such a property is an effective way to ensure the access control security of Internet of Things data markets. However, many researchers on this field cannot avoid potential single point of failure in key distribution, and some key assignment schemes are insecure against collusive attack or sibling attack or collaborative attack. In this paper, we propose a hierarchical key assignment scheme based on multilinear map to solve the multigroup access control in Internet of Things data markets. Compared with previous hierarchical key assignment schemes, our scheme can avoid potential single point of failure in key distribution. Also the central authority of our scheme (corresponding to the data owner in IoT data markets) does not need to assign the corresponding encryption keys to each user directly, and users in each class can obtain the encryption key via only a one-round key agreement protocol. We then show that our scheme satisfies the security of key indistinguishability under decisional multilinear Diffie-Hellman assumption. Finally, comparisons show the efficiency of our scheme and indicates that our proposed scheme can not only resist the potential attacks, but also guarantee the forward and backward security.

Some recent works also have been conducted also that could be good choices for post quantum cryptography, because they are based on primitives that are secure against quantum computer such as lattice based cryptography, e.g.…”
