Enhancing network security : A blockchain-based approach for secure data transfer and user authentication

The abstract emphasizes the growing risk to data in transit due to hacking and unauthorized usage and the need to safeguard that data. The authors propose a blockchain based protocol that improves data integrity and user authentication and allows for secure network communications to defend against these threats. Blockchain’s nature as a decentralized and transparent platform is important here as it is a strong security platform where you can process data and transactions, however the low barriers to entry can make compliance a daunting task in environments at risk for a cyberattack. The most important part of the protocol is that it uses mutual authentication on the monitoring node that is the contact point to the other 2 nodes and meets the requirements of the access authorization directorate. The monitoring node records the MAC address and fingerprint identification of the communication device to allow the contact points to be authorized and not compromised, and the monitoring node also hashes the transmitted data together into a pattern usable in the accounting for mutual authentication. The transactors - sender MAC address, the receiving MAC address, and either MAC address or both, will have session tokens generated for each communication sessions to be used as authorization. It is further validated by either 1-time passwords (OTP), ID transaction, and both tokens logged to verify the authenticity of each recipient MAC address. The transactors or sender and receiver MAC addresses will be hashed and used for validating the data and integrity of the data sent. Overall, the “multi- and layered” authentication and each is identified and recorded in a token account to inherently minimize the risk of unauthorized access, use, or tampering of data in transit. Advanced techniques based on entropy evaluate cryptographic keys’ strength, and comparative evaluations demonstrate that entropic methods generate keys with better entropy compared to older ones; thus, using this assessment method as a better basis for determining an appropriate amount of entropy, the overall security protocol includes biometric authentication (like fingerprints or photos) with other traditional methods. Like other protocols, it defines and incorporates one-time-password (OTP) generation from random image selection created in a grid overall adding another safety factor in ensuring data exchanges. In summary, the security protocol presents a dynamic and sufficient definitive framework as the security measures evolve on it are tailored to fit the present information technology environment with modern cybersecurity operation, thus presenting as a considerable measure for interacting with authenticated communication on secure networks.
