Smart Contract Assisted Blockchain based PKI System. (arXiv:2207.09127v1 [cs.CR])

The proposed smart contract can prevent seven cyber attacks, such as Denial
of Service (DoS), Man in the Middle Attack (MITM), Distributed Denial of
Service (DDoS), 51\%, Injection attacks, Routing Attack, and Eclipse attack.
The Delegated Proof of Stake (DPoS) consensus algorithm used in this model
reduces the number of validators for each transaction which makes it suitable
for lightweight applications. The timing complexity of key/certificate
validation and signature/certificate revocation processes do not depend on the
number of transactions. The …
