Abstract
Implementations of the disclosure provide for binding data to a network in the presence of an entity. In one implementation, a cryptographic system is provided. The cryptographic system includes a memory to store encrypted data, and a processing device, operatively coupled to the memory, to identify a public key for a communications device in response to an indication of a presence of the communications device on a network. A first intermediate is determined in view of the public key for the communications device and in view of an acquisitioning public key. The acquisitioning public key associated with the encrypted data. A second intermediate public key is received from the communications device in view of the first intermediate public key. Thereupon, the encrypted data is decrypted using an encryption key derived at least from the second intermediate public key.
