Abstract: A secure message that includes an attachment is received at a server. The secure message may have a secure layer that indicates that the secure message is at least digitally signed. The secure message may be provided without the attachment to the mobile device over a wireless network. A request may be received from the mobile device to access the attachment. The request may include an attachment identifier (ID) that identifies the attachment in accordance with a message-attachment indexing system. In response to the request to access the attachment, the server may perform an index lookup to find the attachment based upon the attachment ID, may look through the secure layer of the secure message in order to locate the attachment within the secure message, and may render at least an initial portion of the attachment by the server in a format for viewing by the mobile device.

Abstract: A method of authenticating a user of a computing device is proposed, together with computing device on which the method is implemented.

Abstract: A method, device and system for establishing plural modes of operation on a mobile device, including: associating each application on the mobile device with one of a plurality of modes; and restricting access to data on the mobile device to only a subset of applications based on the mode associated for the each application. A system includes connection of an untrusted device to a trusted device and restricting data access for restricted data to a subset of trusted applications on the untrusted device.

Abstract: A method for differentiated access control on a computing device, and the computing device, the method including starting a timer on the computing device; resetting the timer if activity occurs on the computing device prior to the expiration of the timer; and preventing a subset of applications from being launched or enabled on expiry of the timer.

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: Systems and methods for establishing a security-related mode of operation for computing devices. A policy data store contains security mode configuration data related to the computing devices. Security mode configuration data is used in establishing a security-related mode of operation for the computing devices.

Abstract: A method of authenticating a user of a computing device is proposed, together with computing device on which the method is implemented. In the method, an authentication video is displayed on a display. In response to receiving an input at a point in time in the video that matches a pre-selected time reference point, positive authentication is indicated.

Abstract: A method and devices for providing secure data backup from a mobile communication device to an external computing device is described. In one embodiment, there is provided a method of backing up data from a mobile communication device, the method comprising: receiving from an enterprise server an information technology (IT) policy message which includes an encryption key; storing the encryption key in a protected memory of the mobile communication device; receiving a request to backup data stored on the mobile communication device; encrypting the data using the encryption key stored in the protected memory; and transferring the encrypted data from the mobile communication device to an electronic device for storage.

Abstract: A method and apparatus for providing intelligent error messaging is disclosed wherein a user of a mobile communications device is provided with descriptive error messaging information to assist the user in overcoming errors associated with the processing of electronic messages and data.

Abstract: After a predetermined limit for decryption attempts has been exceeded by a user attempting to decrypt an encrypted electronic message or attempting to decrypt a encrypted electronic certificate associated with an electronic message, access to the electronic message may be restricted.

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: A computer-readable medium contains computer-executable instructions. When the instructions are performed by a processor in an electronic device having embedded contactless payment functionality, the performance of the instructions causes the processor to provide data for a contactless payment transaction. In particular, various systems and methods utilize authentication schemes that already exist on a device in which the contactless payment functionality is embedded. One example of such authentication schemes is the use of password protection to lock or unlock the device in which the contactless payment functionality is embedded. Using the password protection functionality may provide varying levels of authentication protection based on the desires of the user. A number of exemplary uses of such a method and apparatus are disclosed herein.

Abstract: Methods and systems for handling on an electronic device a secure message to be sent to a recipient. Data is accessed about a security key associated with the recipient. The received data is used to perform a validity check related to sending a secure message to the recipient. The validity check may uncover an issue that exists with sending a secure message to the recipient. A reason is determined for the validity check issue and is provided to the mobile device's user.

Abstract: A system includes a first wireless-enabled device that transparently stores confidential information and a second wireless-enabled device that stores the same confidential information. The confidential information is to be used to secure a wireless communication link between the first device and the second device. One or both of the first device and the second device is to delete the confidential information upon fulfillment of one or more conditions related to the communication link. The conditions include general timeout, device inactivity, loss of connection over the communication link, a decline in signal strength, and a predefined number of transactions having occurred between the first device and the second device.

Abstract: A symmetric key to be used to secure a communication link between a first device and a second device is generated as follows: a first symmetric key is generated; a second symmetric key is generated; packets communicated between the first device and the second device over communication link are hashed to create a hash result; the first symmetric key, the second symmetric key and the hash result are hashed to generate a third symmetric key to be used to secure the communication link.
