Abstract
This disclosure describes techniques for exchanging keys associated with encrypted media sessions using blockchains. In an example method, one or more encrypted frames are generated by encrypting one or more media frames based on an encryption key. Data indicating a ledger in a blockchain is transmitted to one or more computing devices. The ledger includes a decryption key configured to decrypt the one or more encrypted frames. Data packets are generated by packetizing the one or more encrypted frames. The data packets are transmitted to the one or more computing devices.
