摘要:
Systems and methods for managing data transfers between a secure location and a less secure location. A data transfer checker operating on a mobile device determines whether an attempted data transfer between two locations is permitted. If it is not permitted, then the data transfer is prevented and the user may be notified of the data transfer prevention.

Systems and methods for handling restoration operations for a mobile device. A mobile device receives a kill pill command, wherein the command causes some or all data on the mobile device to be wiped. An indicator is stored to indicate that the kill pill command was sent to the mobile device. The indicator is used to determine whether a program should be wiped from the mobile device.

A challenge response scheme authenticates a requesting device by an authenticating device. The authenticating device generates and issues a challenge to the requesting device. The requesting device combines the challenge with a hash of a password provided by a user, and the combination is further hashed in order to generate a requesting encryption key used to encrypt the user supplied password. The encrypted user supplied password is sent to the authenticating device as a response to the issued challenge. The authenticating device generates an authenticating encryption key by generating the hash of a combination of the challenge and a stored hash of an authenticating device password. The authenticating encryption key is used to decrypt the response in order to retrieve the user-supplied password. If the user-supplied password hash matches the stored authenticating device password hash, the requesting device is authenticated and the authenticating device is in possession of the password.

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:
Systems and methods of connection control for wireless mobile communication devices enabled for communication via a plurality of communication connections are provided. Connection control information associates software applications with communication connections. When a connection request specifying a requested connection is received from a software application, it is determined whether the requested connection is permitted by the connection control information. Where the requested connection is permitted by the connection control information, the requested connection is opened. If the requested connection is a first connection opened by the software application, then the software application is associated with the requested connection in the connection control information.
摘要:
A system and method for processing certificates located in a certificate search. Certificates located in a certificate search are processed at a data server (e.g. a mobile data server) coupled to a computing device (e.g. a mobile device) to determine status data that can be used to indicate the status of those certificates to a user of the computing device. Selected certificates may be downloaded to the computing device for storage, and the downloaded certificates are tracked by the data server. This facilitates the automatic updating of the status of one or more certificates stored on the computing device by the data server, in which updated status data is pushed from the data server to the computing device.
摘要:
A system and method for searching and retrieving certificates, which may be used in the processing of encoded messages. In one embodiment, a certificate synchronization application is programmed to perform certificate searches by querying one or more certificate servers for all certificate authority (CA) certificates and cross-certificates on the certificate servers. In another embodiment, all certificates related to an identified certificate are retrieved from the certificate servers automatically by the certificate synchronization application, where the related certificates comprise at least one of one or more CA certificates and one or more cross-certificates. Embodiments of the invention facilitate at least partial automation of the downloading and establishment of certificate chains, thereby minimizing the need for users to manually search for individual certificates.
摘要:
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.
