Systems and methods for verifying status of digital certificates received by mobile devices. A message server forwards messages sent to a mobile device. The messages may be encrypted with a digital certificate. A mobile device sends a request to the message server. The message server verifies the status of the certificate by comparing it with a previously downloaded CRL and sends a response with this information back to the mobile device.

Systems and methods for updating status of digital certificate subkeys. A request is made to a key server to verify if a given key is revoked. If it is not, then the key with its subkeys is acquired from the key server. If one or more subkeys or signatures of the subkeys are different in the acquired key, then the key is replaced.

A portable wireless user communication device is wirelessly coupled to a second device over a monitored link. If the link is lost or endangered, then a user alarm is activated at the portable wireless user device and/or at the second device to which it is linked (which may also be a portable electronic device). The type of monitoring and/or the type of alarming may be user selectable.

A first wireless device controls its visibility by disabling its discoverable mode or modes upon ascertaining that a second wireless device does not require the first device to be in a discoverable mode in order to establish connections therebetween.
摘要:
A system and method for automatic key and certificate management is disclosed. In particular, a key store in a base computer contains both new and previously viewed cryptographic keys. When a mobile communications device is to be updated with the new keys, the new keys are automatically identified by comparing the keys stored in the base computer with a list of previously viewed keys to determine which new keys are to be marked for download. Upon marking the new keys, the user may be prompted to download the newly identified keys, or they may be downloaded automatically. Once the new keys have been marked, the list of previously viewed keys is updated to include those marked, so that the next time updating occurs, the previously viewed key list will be correct.

A method and apparatus are provided for a user of a mobile wireless communications device to have the option of viewing security status messages in a large or small format depending upon the user's preferences, form factor of the mobile communications device, or the like. In accordance with an exemplary aspect of the invention, a user may opt to display status icons on one row of a display and include an abbreviated text associated with each icon that is displayed when a particular icon is highlighted by the user. If no icon is highlighted by the user, the most important status text (determined based on predetermined criteria) is displayed. The user has the option of switching to a large status display to view additional information relating to the status icons.

Systems and methods for displaying messages to a user, the messages having different levels of security, are provided herein. One method of displaying to a user messages having different levels of security includes receiving a message over a network includes examining an attribute of the message to determine a security-related level associated with the message. A visual indication for display to a device user is generated by the device. Such visual indication is indicative of the determined security-related level, and is configured to be visible during scrolling through a majority of the message text.

Systems and methods are provided for facilitating access to an electronic device. Password information is stored on the electronic device, and on a portable authenticator. When a user attempts to access the electronic device, the user is prompted to enter a password at the electronic device. The portable authenticator determines the validity of the entered password. The electronic device receives the results of the validity determination from the portable authenticator, and provides access to the electronic device based on the received validity determination.
