A system and method of storing in a computer device digital certificate data from a digital certificate are provided. When a digital certificate is received at the computer device, it is determined whether the digital certificate data in the digital certificate is stored in a first memory store in the computer device. The digital certificate data is stored in the first memory store upon determining that the digital certificate data is not stored in the first memory store.

An electronic device includes password protected functionality using a password that can be changed by the user. A user-specified password is stored in association with unique version data that is subsequently provided to help user recall of the password associated therewith.
摘要:
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.
摘要:
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 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.
摘要:
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.
摘要:
Systems and methods for establishing a data connection between a mobile device and a peripheral. The mobile device is configured to determine whether to handle user approval of the data connection between the mobile device and the peripheral. Through the mobile device, an input mechanism is provided for the user to provide input. The input is used in determining whether to approve the data connection between the mobile device and the peripheral.

Systems and methods for providing access to data. When an application needs to perform an action that requires access to data, the application acquires a “ticket” in order to access the data. While the application holds the ticket, it is given access to the data.
摘要:
A method and system are provided for processing encrypted messages at a mobile device. A mobile device receives an encrypted message that comprises encrypted content as well as encryption information for accessing the encrypted content. At the mobile device, the encryption accessing information is obtained and stored to memory. The encryption accessing information is retrieved from memory in order to decrypt the encrypted content when the encrypted message is subsequently accessed.
