    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： A method and portable electronic device for processing images are provided. Images are stored electronically at a remote server as attachments to message data, message data received at the portable electronic device with indicators identifying corresponding attachments to the message data. The portable electronic device comprises a processing unit interconnected with an input device, and a display device. First input data is received indicative that one of the indicators, corresponding to one of the images, has been selected, causing the image to be retrieved from the remote server. The received image is displayed at the display device. Second input data is received indicative that a next one of the images is to be displayed, the second input data received while the first retrieved images is displayed at the display device. The next images is then received from the remote server and processed to display it at the display device.
