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. A first device may output a first request to a second device to establish a communication session between the first device and the second device, where the request includes a first value. The first device may receive a second request from the second device, including a second value, to establish the communication session between the first device and the second device. The first device may determine, based on a comparison of the first and second values, that the first device should initiate an establishment procedure of a blockchain associated with the communication session between the first device and the second device, and may accordingly output a blockchain establishment message to a set of devices.
