“…erefore, the digital twin of the Great Wall is to recreate a corresponding "virtual Great Wall" in cyberspace, forming a physical Great Wall in the physical dimension and a digital Great Wall in the information dimension (historical information, status quo information) and coexisting and blending the virtual and the real pattern, through real-time feedback of multiple types of sensors to the digital world, intelligent, consistent, and complete visual mapping, and simulation can be realized [19].…”

In order to preserve and inherit material cultural heritage, the author proposes a method for digital construction of the Great Wall’s cultural heritage based on digital twin. This method discusses the connotation of the whole life cycle of the Great Wall digital twin, proposes the research path and content of the digital twin construction of the Great Wall cultural heritage, and conducts the application of the Great Wall digital twin to evaluate the application effect. The evaluation results show that users’ overall satisfaction with Great Wall’s digital twin application is relatively high, and the average score of each indicator is above 4, and the functional experience is slightly poor. Conclusion. This method can provide full life cycle visualization services for the digital archiving, application, and decision-making of the Great Wall cultural heritage and provide theoretical and methodological references for the preservation and inheritance of material cultural heritage.

“…d ) using their private keys of ECIES. Due to the difficulty of the Diffie-Hellman problem [44] and the elliptic curve discrete logarithm problem, no microgrid can decrypt d except the chosen one since it is the only one having the private key corresponding to the public key used in the encryption. Concerning the decision understanding, the format of data to be exchanged is determined in the protocol setup phase, implying that when the chosen seller decrypts the decision, it must extract x best and the contact c i , then it must compare the decrypted secret with the secret that it created in the auction step to verify that it is the selected bidder (which should be the same, otherwise it could not decrypt the decision [45]).…”

The decision is kept private even after the publication on the blockchain due to the difficulty of the elliptic curve Diffie-Hellman problem [44]. No one except the chosen bidder can open the decision since it is the only one having the private key correspondent to the cipher decision.…”

Secure distributed power trading protocol for networked microgrids based on blockchain and elliptic curve cryptography

et al. 2022

The definition of an electricity trading protocol among microgrids is not an easy task to perform due to the grid's increasing requirements. In fact, a trading process must provide security and especially privacy of the buyer and seller identities as well as prices. Also, guaranteeing a financial profit to trading parties is of great importnace. Moreover, matching the full distributed paradigm is required since it will be executed in a distributed system. All these constraints must be satisfied with consideration to the computational costs especially data storage. In this paper, an electricity trading protocol is introduced to ensure: (1) the security and privacy of buyers, sellers, and sales information, (2) the trading process distribution, and (3) the minimisation of the stored data. The protocol builds upon the blockchain technology and the Elliptic Curve Cryptography. To achieve the protocol goals, a new architecture based on a concept of membership of microgrids to families and groups of families is defined. The proposed protocol is implemented using Java programming langauge. An honest‐but‐curious‐adversary security model is applied to a formal case study to prove security of the protocol.

“…In particular, the emergence of 5G promotes the rapid development of the Internet of Things (IoT) [1][2][3][4]. Though the IoT achieves information interconnection, it also transmits much private information through the network making it essential to protect the security of private information [5][6][7]. And due to the openness of the wireless channel, it also has many security risks.…”

Efficient and secure communication scheme for OFDM system based on physical layer non‐reconciled keys

et al. 2022

The secure communication scheme based on physical layer non-reconciled keys receives extensive attention due to its high encryption rate. However, the mismatched secret bit sequences between the two users leads to higher BER and lower coding efficiency for this type of scheme. To solve this problem, this paper proposes an efficient and secure communication scheme for OFDM system with non-reconciled keys. Initially, an adaptive coding method is designed to encode information blocks with different code rates to improve the overall efficiency. Then, on this basis, a sorting xor encryption algorithm is designed to reduce the bit error rate by sorting the channel estimation value and mapping them to corresponding sub-channels. Theoretical analysis and simulation results indicate that this scheme can effectively reduce the bit error rate and improve the efficiency of information coding compared to the existing method.
