A system and method for sending encrypted messages to a distribution list that facilitates the sending of such messages only to individuals or other entities associated with the distribution list that will be able to read the message. In one embodiment, the method comprises the steps of: identifying a distribution list address in a message; determining one or more member addresses associated with the distribution list address; for each member address, determining if a public key for a member identified by the respective member address is available on the computing device; encrypting the message to each member identified by the one or more member addresses for which a public key for the respective member is available on the computing device; sending the encrypted message to the distribution list address if each of the one or more member addresses associated with the distribution list identifies a member for which a public key is available on the computing device; and sending the message to each of the one or more member addresses that identifies a member for which a public key is available on the computing device otherwise.

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.

In one embodiment, a scheme is provided for managing secure registration of a mobile communications device. Upon being provided with an upgraded registration process that requires encryption, the mobile communications device has the option of continuing to register with a network node using a downgraded registration process within a specified time window which involves unencrypted registration requests and responses. Thereafter, the mobile communications device is operable to select between the upgraded and downgraded registration processes.

In a system with a policy server, a first device able to communicate with the policy server and a second device able to communicate with the first device and unable to communicate with the policy server, the first device is to act as a policy proxy. The policy server may communicate to the first device a policy for the second device, and the first device may communicate the policy to the second device.

In one embodiment, a scheme is provided for securing a personalized indicium assigned to a mobile communications device. Upon detecting at a network node that an address associated with the mobile communications device has changed, a challenge-and-response procedure is negotiated between the mobile communications device and the network node for authenticating the personalized indicium using a shared authentication key.

A method carried out by an electronic device enabled to send and receive electronic messages over a network, including: determining if a new electronic message received by the device is part of a message thread that includes the new message and at least one prior electronic message previously received at the device; and if the new message is determined to be part of a message thread, comparing address information of the new message with address information of the at least one prior electronic message in the message thread to determine if there has been a change in addressed recipients between the new message and the at least one prior electronic message, and if so, providing a notification to a user of the device of the existence of the change.
摘要:
A method and system for external message address detection and warning is disclosed. A messaging application permits a message sender to create a message composition intended to be sent to at least one message address. The message address includes a first portion identifying the message address as belonging to a group of addresses and a second portion identifying the message address as belonging to a specific address within the group. A determination is made if the first portion of the message address identifies the message address as belonging to a predetermined group or groups of addresses; if the first portion does not identify the message address as belonging to the predetermined group or groups of addresses, a warning is provide to the user of the device.
