SummaryWith the development of technology, data has become more accessible. The storage of critical and valuable information is getting harder and harder with the increase of cyber attacks and vulnerabilities of network and internet. The centralized storage of data causes security and privacy problems. As a remedy to these problems, blockchain has occurred. The reliability, transparency, integrity and confidentiality of the data have been increased with the blockchain technology. Blockchain maintains the immutability of the data with cryptographic hash algorithms. The data is kept in distributed structures with the consensus algorithms so that it is not lost. Projects and studies using blockchain technology have shown that data stored in centralized structures is not as reliable as data that is distributed and secured by cryptographic algorithms, smart contracts, and consensus. The data of flights, which is a critical data, has a great place in world transportation. The parameters inside the black boxes guide us on why the aircrafts have crashed: whether the responsibility belongs to the manufacturer, to the pilot, or to the aircraft technicians. In this way, the real reasons of the accident may be determined and measures can be taken for the accidents that may occur afterwards. In addition, the safe delivery of all black box data to the interested parties and its storage in a way that is immutable will not only benefit to the manufacturer's self‐development by processing the data, but also help flight companies to find optimum flight data. Both the flight companies and the manufacturer will be able to read the black box data, thus the suspicion of data manipulation will be eliminated and the data will become more transparent. In this study, a system is proposed in which an aircraft's black box data can be saved safely and securely with the help of blockchain technology.

“…Firstly, the receiver checks the value r 1 from the signature of the first transaction tx 1 as the x-coordinate to find the point X on the elliptic curve. This point can also be obtained during the process of verifying the validity of the ECDSA signature [21]. Secondly, the receiver uses the deterministic function map ′ with inputs X and h 2 to derive the random number k 2 chose by the sender to sign the second transaction tx 2 .…”

As a decentralized network infrastructure, the data sent to the blockchain are public and temper-evident. The cover of massive normal transactions in a blockchain network is ideal for constructing a stable and reliable covert channel to achieve one-to-many group covert communication. Existing blockchain-based covert communication schemes face challenges in balancing concealment, embedding rate and filtering efficiency, making them unsuitable for direct extension to group scenarios. Adopting a key-leakage scheme can increase the channel capacity while maintaining high concealment from external adversaries. However, it will also expose more knowledge to the receiver. A malicious receiver has the ability to steal a sender’s identity or replay historical transactions to control the entire channel. In this paper, we define the capabilities of malicious receivers in blockchain-based group covert communication scenarios and propose a group covert communication scheme resistant to transaction forgery attacks. Theoretical analysis and experiments prove that our covert transactions do not have any transaction correlativity, ensuring the unique authenticity of the sender’s identity while maintaining supreme concealment compared with the existing schemes. The precision and recall of machine learning detection results can reach 0.57–0.62 (0.5 is the ideal value).

“…Inversion operation could also be costly as it is used in both signature generation and signature verification. Genç and Afacan [3] implement ECDSA with reduced inversion operations by moving the inversion operation into the key pair generation. That is, replace R = kG with R = (k -1 mod n)G. Moreover, s in the signature generation is replaced as s = d(t -h) mod n. Inversion operations in w 1 and w 2 in signature verification is removed.…”

“…The author implemented the ECDSA function in python. The paper also explains the hash function, Elliptic Curve Cryptography (ECC), Elliptic curve discrete logarithm problem (ECDLP) and key pair generation in ECDSA [3]. In the paper Hardware implementation of elliptic curve digital signature algorithm (ECDSA) on Koblitz curves, ECDSA's hardware implementation based on Koblitz subfield curves with a key length of 163-bit is introduced.…”
