The present invention provides a central processing unit for processing at least one encrypted software. The encrypted software comprises at least one encrypted software section. The encrypted software section is encrypted with a management key MK, and the MK being encrypted with a device key DK as a encrypted MK. The central processing unit comprises processing and cache unit, and cryptographic unit. The cryptographic unit comprises device key storage unit for storing the DK, a plurality of management key storage units for storing MKs, wherein each management key storage unit corresponding to a management key index MKI, and decryption unit. The decryption unit decrypts a encrypted MK with the DK to obtain a MK, stores the MK to a management key storage unit, and output a MKI corresponding to the management key storage unit, thus the MKI is used to correspond to the encrypted software section. Wherein, the decryption unit invokes corresponding MK according to the MKI and decrypts the encrypted software section, and directly transfers the decrypted software code and/or data to the processing and cache unit.

A method and system for building an embedded software package for a target system including creating a cross-compiling stub in the target system, wherein the stub accesses a compiling tool at a remote location, starting a software package building process at the target system, and intercepting a compiling command coming from said software package building process and forwarding the compiling commands to said remote compiling server using the cross-compiling tool stub so that a source file will be compiled by a corresponding cross-compiling tool in the remote compiling server. The method and system allow a developer of software for an embedded system be able to start a software package building process on the target system as in the native compilation situation, and have the actual compiling of the source file in the software package be performed by cross-compiling tools in another computer with high performance.

A method and system for maintaining originality-related information about elements in an editable object. It is determined that an element has been edited in the editable object. The originality-related information about the element, including the element's creator, is identified and recorded by embedding the originality-related information in the editable object, storing the originality-related information in an attached file, or storing the originality-related information in association with the element in a repository configured to be shared by different editable objects and further configured to be queried for elements of the different editable objects in association with originality-related information pertaining to the elements of the different editable objects. Whether the element is in compliance with a policy relating to the originality-related information about the element is assessed, and a result of the assessing (indicating compliance or non-compliance of the element with the policy) may be transmitted to a user.

A directional information delivery method and system, wherein a wide-angle electromagnetic wave transmitter is attached on each object for transmitting channel identification that indicates the transferring channel of the information of the exhibited item attached with the wide-angle electromagnetic wave transmitter to a specified area in wide angle, while each portable client device is provided with a directional electromagnetic wave receiver. When a user points the client device he/she to an object, it can receive the electromagnetic wave from that exhibited item. Then, the client device obtains a channel identification from that electromagnetic wave, and establishes a connection with an information delivery sub-system based on the obtained channel identification to obtain information about that exhibited item from the channel and to render that information. In this way, a user can select simply by pointing at the exhibited item with the client device, thereby accurately obtaining the information about the exhibited item of interest.

Directional information delivery system and method

An apparatus and method for storing data, and a method for reading data. The apparatus for storing data of the present invention comprises at least one bridge for storing binary data. Each bridge has four legs and represents a bit with a nonequilibrium state between two juncture points. The apparatus for storing data further comprises at least one comparator respectively connected between the two juncture points of each of the at least one bridge for determining a value of the bit represented by the bridge.
