    Abstract: 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.

    Abstract: A challenge response scheme includes the authentication of a requesting device by an authenticating device. The authenticating device generates a challenge that is issued to the requesting device. The requesting device combines the challenge with a hash of a password provided by a user of the requesting device, and the combination of the hash of the password and the challenge is further hashed in order to generate a requesting encryption key that is used to encrypt the user supplied password. The encrypted user supplied password is sent to the authenticating device as a response to the issued challenge. The authenticating device generates an authenticating encryption key by generating the hash of a combination of the challenge and a stored hash of an authenticating device password. The authenticating encryption key is used to decrypt the response in order to retrieve the user-supplied password. If a hash of the user-supplied password matches the stored hash of the authenticating device password, then the requesting device has been authenticated and the authenticating device is in possession of the password.

    Abstract: A system and method for generating keys that can be used for encrypting and decrypting PIN messages transmitted between mobile devices. In one embodiment, the method comprises defining a function f, where f(x,y)=f(y,x), and for each of first and second mobile devices, evaluating f with one of x and y having the value of the PIN of the respective mobile device. Each one of the first and second mobile devices can then compute a shared messaging key by evaluating f with the other of x and y having the value of the PIN of the other mobile device. The shared key can then be used specifically to encrypt and decrypt PIN messages transmitted between those two mobile devices.

    Abstract: A mobile communications device for the display of an incrementally received message includes a message viewer application for scanning the received portions of the message. On determination that the received portion of the message includes a first displayable portion of the message content, the system signals to a message server to halt the message server from forwarding further portions of the message content. The system provides a mechanism for the user of the mobile communications device to cause the mobile communications device to further signal the the message server to recommence the forwarding of further portions of the secure message content to permit the verification of the e-mail based on the further portions of the secure message content.

    Abstract: A method and apparatus for processing digitally signed messages in which address mismatch errors are detected. In at least one aspect, the number of address mismatch errors reported to a user for a message may be minimized for messages that properly incorporate message portions signed by someone other than the sender of the message, as may be the case where the message contains a conversation thread for example, by performing at least one predetermined action for digital signatures corresponding to signed data appearing after a message separator. The message separator may indicate that the message contains data from an older forwarded message or from an older message that has been replied to, for example. The at least one-predetermined action may comprise bypassing verification of address matches for those digital signatures, or verifying address matches for those digital signatures but suppressing user notification of any address mismatch errors, for example.

    Abstract: A system includes a server, a first client device to communicate in an authenticated and secured manner with the server over a first communication link, and a second client device to communicate in an authenticated and secured manner with the first client device over a second communication link. The first client device is to cause the server and the second client device to share cryptography information. The cryptography information may then be used to secure a third communication link between the server and the second client device that does not include the first client device.
