Security model for a layout engine and scripting engine

A computer-implemented method comprising:ncreating at least one layout engine object in a layout engine memory space;creating at least one scripting language object in a scripting engine memory space;creating a custom object that is configured to represent relationships between objects in the scripting engine memory space and objects in the layout engine memory space, the custom object comprising a pointer to the at least one scripting language object and a pointer to the at least one scripting language object, and the custom object providing a linkage between the at least one scripting language object and the at least one layout engine object; andusing at least one security module to provide secure information transfer during access to the at least one layout engine object and the at least one scripting language object, the security module configured to enable controlled access to an Application Programming Interface (API) associated with a scripting language of the scripting engine.

A computer program product comprising one or more computer-readable hardware storage devices comprising computer readable instructions which, when executed, implement:na Web browser configured to enable rendering of a Web page, the Web browser being configured to create:nat least one layout engine object in a layout engine memory space;at least one scripting language object in a scripting engine memory space;a custom object that is configured to represent relationships between objects in the scripting engine memory space and objects in the layout engine memory space, the custom object comprising a pointer to the at least one scripting language object and a pointer to the at least one scripting language object, and the custom object providing a linkage between the at least one scripting language object and the at least one layout engine object; andat least one security module configured to enable secure information transfer between the scripting engine memory space and the layout engine memory space.

A computing device comprising:none or more processors; andone or more computer-readable storage media comprising computer readable instructions which, when executed upon the one or more processors, implement a method comprising:ncreating at least one layout engine object in a layout engine memory space;creating at least one scripting language object in a scripting engine memory space;creating a custom object that is configured to represent relationships between objects in the scripting engine memory space and objects in the layout engine memory space, the custom object comprising a pointer to the at least one scripting language object and a pointer to the at least one scripting language object, and the custom object providing a linkage between the at least one scripting language object and the at least one layout engine object; andusing at least one security module to provide secure information transfer during access to the at least one layout engine object and the at least one scripting language object, the security module configured to enable controlled access to an Application Programming Interface (API) associated with a scripting language of the scripting engine.
