摘要： A system and method for selectively securing data from unauthorized access on a client device storing a plurality of data types with reference to an authorization level indicated in a command. A command is received at a client device comprising an authorization level indicator. Based on at least one predefined rule, which may be implemented in an IT policy stored at the client device, each of the plurality of data types to be secured is determined, and then the data corresponding to those types is secured. The data may be secured by encrypting and/or deleting the data at the client device. The predefined rules associated with each authorization level may be configured by a user or administrator having an authorization level that exceeds the associated authorization level.

摘要： Systems and methods for processing encoded messages within a wireless communications system are disclosed. A server within the wireless communications system determines whether the size of an encoded message is too large for a wireless communications device. If the message is too large, the server removes part of the message and sends an abbreviated message to the wireless device, together with additional information relating to processing of the encoded message, such as, for example, hash context values, that assist the wireless communications device in verifying the abbreviated message.

摘要： A system and method for securing data for redirecting and transporting over a wireless network are generally described herein. In accordance with some embodiments, when it is determined that an electronic message that is protected with a first encryption algorithm is to be transported over a wireless network to a wireless device, the electronic message is converted to a data structure that is recognizable by the wireless device and the data structure is encrypted with a second encryption algorithm using a random session key. The second encryption algorithm has a stronger security than the first encryption algorithm. The random session key is encrypted with a public key and packets that comprise the encrypted data structure and the encrypted random session key are transmitted to the wireless device over the wireless network.

摘要： A mobile wireless communication device also has at least one wired communication port. Enhanced security is achieved by permitting the device to automatically disable one or more wireless ports when connected to a wired port. Specific combinations/permutations of such automatic control may be effected by use of an IT Policy also resident on the device.

摘要： 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 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.

摘要： System and methods for processing encoded messages at a message receiver are described. Encoded message processing is performed in multiple stages. In a first stage, a new received message is at least partially decoded by performing any decoding operations that require no user input and a resulting context object is stored in memory, before a user is notified that the new message has been received. When the user accesses the new message, any further required decoding operations are performed on the stored context object in a second stage of processing. The message can subsequently be displayed or otherwise processed relatively quickly, without repeating the first stage decoding operations. Decoding operations may include signature verification, decryption, other types of decoding, or some combination thereof.

摘要： A method for securing data and resetting a password using a content protection key is provided, in which the content protection key itself is protected by a password. A content protection key is also protected at a data storage device with a key encryption key generated in collaboration with an additional device such as a server. The server stores a private key required to regenerate the key encryption key, but this private key is not provided from the server to the data storage device; rather, a public key derived from the private key is provided by the server. The data storage device combines the received public key and a further private key to derive the key encryption key; the further private key itself is not stored by the data storage device, but rather its matching public key is stored. The content protection key is then encrypted using a password and the derived key encryption key. If the password is lost, data from the server and from the data storage device may be combined to recreate the key encryption key.
