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 first entity may generate an asymmetric key pair that includes a public key and a private key, and may provide the public key, along with a key identifier, to a blockchain system for retrieval by multiple other entities. For example, the entities may be engaged in a secure group communication session, in which communications are encrypted and may be decrypted using one or more keys, including the public key. The other entities may identify the public key, as recorded to the blockchain system, based on the key identifier. Participants may be added to or removed from the secure group communication session.
