A wireless domain ( ) sets a security policy for all mobile communication devices ( ) within the domain by use of a system entry proxy server ( ). A developer makes an application or code segment available at a developer station ( ). The application is certified by a certificate defining a developer security setting. The user of the mobile communication device initiates a download of the application so that it can be installed onto the mobile communication device. The application is downloaded through the system entry proxy server which authenticates the application, then re-certifies it with a compact certificate including an operator defined security policy. In this way the operator can control which resources of the mobile communication device are accessed by all applications coming into the wireless domain.

Method for validating an application for use in a mobile communication device

A new process for determining the administrator of a mobile communications device, e.g., a wireless cellular telephone, two-way pager, or laptop computer, connectable to a telecommunications network. The system and methods described provide processes for determining whether a Subscriber Entity Module (SIM) is present with a digital certificate for a domain of an administrator, e.g., a network operator, for designating administrative responsibilities in a mobile communications device. A mechanism is provided to designate administrative privileges to an entity by the owner of the mobile communications device.

Method and apparatus for designating administrative responsibilities in a mobile communications device

The present invention includes a method ( ), client device ( ), server ( ) and article of manufacture ( ) for compressing/decompressing a universal resource identifier URI. The method includes the steps of: determining, starting at a first end of a string, a first count of characters that sequentially match between a previous register and a current register; determining, starting at a second end of the string, a second count of characters that sequentially match between the previous register and the current register, and encoding the URI based on the first count and the second count.

Method, client device, server and article of manufacture for compressing universal resource identifiers using left/right string substitution

The present invention includes a method (,), client device (,), server (,) and article of manufacture (,) for compressing/decompressing a current universal resource identifier URI using an immediately previous URI. The method for compressing the URI includes the steps of: partitioning the immediately previous URI and the current URI into a predetermined number of components; and comparing each component of the current URI with each corresponding component of the immediately previous URI from left-to-right LR and from right-to-left RL and encoding the current URI using concatenated compression indicators in accordance with counts of LR-matched characters, RL matched characters and uncompressed characters, wherein an escape byte is added to an end of the uncompressed characters when a last uncompressed character has a most significant bit set to one.

A computer-readable instruction stream is verified to determine that it does not violate the run-time security constraints of the execution environment (150). The computer-readable instruction stream after verification is stored in a storage device (140). The execution environment (150) retrieves the computer-readable instruction stream from the storage device (14) and verifies that the computer-readable instruction stream has not been modified. Upon verification, the computer-readable instruction stream is executed, while bypassing verification of the run-time security constraints of the execution environment (150).

Method and system for reducing time and power requirements for executing

A method (500), client device (700), server (800) and computer readable medium (900) provide a scheme for negotiating compression of universal resource identifiers. The method includes: (1) sending, by a client, a request to a server wherein the request includes an uncompressed universal resource identifier URI and a list of compression techniques of the client; (2) determining, by the server, an intersection of the list of compression techniques of the client and a list of compression techniques of the server and providing a response to the client that includes the intersection and information identified by the URI; (3) subsequently requesting, by the client, information wherein one of: (4) decompressing, by the server, the compressed URI using the compression technique indicated in the subsequent request; and (5) responding, by the server, wherein the response includes information requested as identified by the compressed URI.
