    Abstract: Systems and methods for processing encoded messages within a wireless communications system are disclosed. A server within the wireless communications system performs signature verification of an encoded message and provides, together with the message, an indication to the mobile device that the message has been verified. In addition, the server provides supplemental information, such as, for example, a hash of the certificate or certificate chain used to verify the message, to the device, to enable the device to perform additional checks on the certificate, such as, for example, validity checks, trust checks, strength checks, or the like.

    Abstract: A system and method are provided for pre-processing encrypted and/or signed messages at a host system before the message is transmitted to a wireless mobile communication device. The message is received at the host system from a message sender. There is a determination as to whether any of the message receivers has a corresponding wireless mobile communication device. For each message receiver that has a corresponding wireless mobile communication device, the message is processed so as to modify the message with respect to one or more encryption and/or authentication aspects. The processed message is transmitted to a wireless mobile communication device that corresponds to the first message receiver. The system and method may include post-processing messages sent from a wireless mobile communications device to a host system. Authentication and/or encryption message processing is performed upon the message. The processed message may then be sent through the host system to one or more receivers.

    Abstract: 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.

    Abstract: This disclosure relates to management of privileges associated with applications accessible by users of electronic devices. In one aspect, an electronic device detects that a privilege has been revoked, shuts down any application running on the electronic device that has previously accessed the privilege, and restarts any application that was shut down, the restarted application no longer having any access to the revoked privilege. In another aspect, an electronic device keeps a log of which applications have previously accessed which privileges, receives a new set of privileges associated with applications, determines that a privilege has been revoked, and if the log indicates that an application previously accessed the privilege, resets the electronic device. In a further aspect, a method sets privileges associated with applications, records which electronic devices have which applications, revokes a privilege, and instructs those electronic devices having applications to which the privilege is associated to reset themselves.
