Abstract
A system described herein provides for the secure maintaining and providing of information, such as public keys used in Public Key Infrastructure ('PKI') techniques or other techniques, using a distributed ledger (e.g., “blockchain”) system with a fallback to a key escrow system. A first device may encrypt a communication using a first key, and output the encrypted communication to a second device. The first device may attempt to record a second key, that is associated with the first key, to the blockchain system, and may determine that the second key was not recorded to the blockchain system based on the attempt. The first device may output the second key to a third device based on determining that the second key was not recorded to the blockchain system. The second device may obtain the second key from the third device, and use the second key to decrypt the encrypted communication.
