Abstract
Message decryption dependent on third-party confirmation of a condition precedent is disclosed. A message is encrypted with a message encryption key to form an encrypted message. A message decryption key that is configured to decrypt the encrypted message is encrypted with a key of a first entity to which the message is to be disclosed upon occurrence of a condition precedent to form an encrypted message decryption key. The encrypted message decryption key is encrypted with a key of a second entity configured to confirm the occurrence of the condition precedent to form a double encrypted message decryption key. A condition identifier that identifies the condition precedent is generated. The encrypted message, the double encrypted message decryption key, and the condition identifier are sent to the first entity.
