Interacting digitally communicating devices cooperate to schedule future meetings include a capability to handle conditional acceptance of meeting requests. For example, a conditional acceptance may be subject to Boolean logic functions of the acceptance status(es) of other meeting invitees (e.g., the condition that another specific one or more invitees also accept the meeting request).

A system and method is provided for managing multiple smart card sessions with multiple communications or computing devices in association with a single smart card reader. A wireless smart card reader is provided for communicating with a plurality of devices requiring smart card functionality in a number of smart card sessions, in which each smart card session is addressed with an identifier identifying a single device. The smart card session is secured by a wireless connection pairing and by a secure pairing, such that each connection between the smart card reader and a device is secured against all other devices in communication with the smart card reader using a master connection key, which is unique for each device.

A system and method for retrieving certificates and/or verifying the revocation status of certificates. In one embodiment, when a user opens a digitally signed message, a certificate that is required to verify the digital signature on the message may be automatically retrieved if it is not stored on the user's computing device (e.g. a mobile device), eliminating the need for users to initiate the task manually. Verification of the digital signature may also be automatically performed by the application after the certificate is retrieved. Verification of the revocation status of a certificate may also be automatically performed if it is determined that the time that has elapsed since the status was last updated exceeds a pre-specified limit.

The described embodiments relate generally to devices, methods and systems for managing access to a memory card, such as a smart card, by a plurality of accessing devices. Certain embodiments relate to a smart card reader (SCR) for managing concurrent access to a smart card by a plurality of accessing devices, the SCR comprising: a processor; a channel manager responsive to the processor for interfacing with the smart card; a communication interface responsive to the channel manager for communicating with the plurality of accessing devices; and wherein, when a session is open on a first channel between a first accessing device and the smart card and the channel manager is configured to issue an open channel command to the smart card to cause the smart card to open a second channel between the smart card and the second accessing device in response to the session request.

In at least one embodiment, there is provided a mobile wireless device comprising: a microprocessor and memory, the memory comprising a set of control settings used to control a plurality of device operations; wherein the microprocessor is configured to: receive a first digital signature key for verifying digital signatures on software applications to be installed on the device; determine if any digital signature keys for verifying digital signatures on software applications to be installed on the device exist on the device, and if not, store the received first digital signature key in the memory; receive a software application for installation on the device; verify a digital signature on the received software application using the first digital signature key; and install the software application on the device if the digital signature on the received software application is successfully verified.

Systems and methods of owner application control of an electronic device are provided. Owner application control information is stored on the electronic device and/or one or more remote servers. Owner application control information is consulted to determine if one or more required applications are available for execution on the electronic device. If not, one or more required applications not available are downloaded and installed. This could be in a manner transparent to the user of the electronic device. If one or more required applications are not available on the electronic device, the device can be functionally disabled in whole, or in part, until one or more required applications are available.

A smart card, system, and method for securely authorizing a user or user device using the smart card is provided. The smart card is configured to provide, upon initialization or a request for authentication, a public key to the user input device such that the PIN or password entered by the user is encrypted before transmission to the smart card via a smart card reader. The smart card then decrypts the PIN or password to authorize the user. Preferably, the smart card is configured to provide both a public key and a nonce to the user input device, which then encrypts a concatenation or other combination of the nonce and the user-input PIN or password before transmission to the smart card. The smart card reader thus never receives a copy of the PIN or password in the clear, allowing the smart card to be used with untrusted smart card readers.
摘要:
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. For example, when the mobile device is being used to decrypt a cryptographically secured electronic message, and a problem is encountered, program logic of the device provides the user with (1) an indication of exactly what problem is preventing opening of the message, for example, a required cryptographic key is not available; (2) an indication of exactly what may be done to overcome the problem, for example, what utilities should be run on the device; and (3) exactly what data, if any, needs to be downloaded to the device, for example, what cryptographic keys should be downloaded.
摘要:
A system and method for registering entities for code signing services. The entities may be software application developers or other individuals or entities that wish to have applications digitally signed. Signing of the applications may be required in order to enable the applications to access sensitive APIs and associated resources of a computing device when the applications are executed on the computing device. In one embodiment, a method of registering entities for code signing services will comprise the step of transmitting at least some account data to the registering individual or entity using an out-of-band communication system. This provides added security that the individual or entity registering for a code signing service is who that individual or entity purports to be.

Embodiments of the systems and methods described herein facilitate the transmitting, receiving, and processing of encoded messages wherein the header fields in the message header are protected. In one embodiment, the contents of the header fields to be protected are inserted into the message body as one or more additional lines of text, for example, prior to encoding and transmitting the message to a message recipient. Upon receipt of the message, the message recipient processes the encoded message such that the contents of the protected header fields can be extracted from the message body. Accordingly, by inserting the contents of the header fields to be protected into the message body, the header fields may be protected using existing standards and protocols for facilitating secure message communication.
