PKI and Blockchain

signed and registered after successful verification, it is very difficult to tamper with the public key of an entity, and thus, it ensures security.

Update of a Public Key

When an entity wants to update its public key, it submits its ID, the old key, and the new key to the blockchain. All the nodes of the blockchain verify that the old public key corresponds to the entity and notify their approval. When the majority of the nodes approve, a new block is created with the updated value of the public key.

The article gives a brief overview of Public Key Infrastructure and Blockchain. Interested readers who want to know more about how different cryptographic algorithms and Public Key Infrastructure work may want to refer to the book “Cryptography And Public Key Infrastructure.”
