Abstract
A system described herein provide for the secure maintaining and providing of information, such as public keys used in Public Key Infrastructure ('PKI') techniques or other techniques, using a secure distributed ledger (e.g., “blockchain”) system. A blockchain system may be utilized in lieu of a key escrow system in the exchange and/or providing of public keys in a Diffie-Hellman key exchange technique or other type of technique in which public keys are provided from one entity to another. A first entity may generate an asymmetric key pair that includes a public key and a private key, and may provide the public key to a blockchain system for retrieval by one or more other entities. For example, the entities may be engaged in a secure messaging session, in which messages are encrypted and may be decrypted using one or more keys, including the public key.
