Abstract
A security client of a mobile computing platform transmits a request for the secret key to a key server. The request includes environmental data characterizing a current state of the environment of the node and establishes a cryptographic heartbeat with the key server. The security client receives a secret key from the key server, stores the secret key in volatile memory and decrypts the encrypted file using the secret key to create a decrypted file in the volatile memory. The security client monitors a time since a last authenticated heartbeat message was received. Responsive to the time exceeding a predetermined timeout window or responsive to receiving a message from the key server indicating that authorization to the decrypted file is revoked or responsive to determining that the node is not in an authorized environment, the security client deletes the secret key from the volatile memory and closes the decrypted file.
