    摘要: A method for secure bidirectional communication between two systems is described. A first key pair and a second key pair are generated, the latter including a second public key that is generated based upon a shared secret. First and second public keys are sent to a second system, and third and fourth public keys are received from the second system. The fourth public key is generated based upon the shared secret. A master key for encrypting messages is calculated based upon a first private key, a second private key, the third public key and the fourth public key. For re-keying, a new second key pair having a new second public key and a new second private key is generated, and a new fourth public key is received. A new master key is calculated using elliptic curve calculations using the new second private key and the new fourth public key.

    摘要: According to embodiments described in the specification, an electronic communication device and method for processing messages are provided. The method comprises receiving message data at a processor of the computing device, the message data comprising one or more of an address, a subject and a body; receiving a state indicator at the processor, the state indicator being an indication of a state of the message data; storing the message data and the state indicator in a memory of the computing device, the state indicator being stored in association with the message data; determining, at the processor of the computing device, if the state indicator indicates that the message data is in a draft state; and when the determination is affirmative, preventing transmission of the message data.
