-Public-key infrastructure (PKI) is an information security measure that generates a [public key](/glossary/#public-key) and [private key](/glossary/#private-key) for an entity. Public-key [cryptography](/glossary/#cryptography) is used in blockchain networks to authenticate user identities and prove ownership of digital assets.

-Some decentralized identifiers, such as an Ethereum account, have public and private keys. The public key identifies the account's controller, while the private keys can sign and decrypt messages for this account. PKI provides proofs needed to authenticate entities and prevent impersonation and use of fake identities, using [cryptographic signatures](https://andersbrownworth.com/blockchain/public-private-keys/) to verify all claims.
