Abstract
An apparatus is provided for providing security in a computer system. The apparatus comprises an address generator, a multi-level lookup table, and a cache. The address generator is adapted for producing an address associated with a memory location in the computer system. The multi-level lookup table is adapted for receiving at least a portion of said address and delivering security attributes stored therein associated with said address, wherein the security attributes are associated with each page of memory in the computer system. The cache is a high-speed memory that contains a subset of the information contained in the multi-level lookup table, and may be used to speed the overall retrieval of the requested security attributes when the requested information is present in the cache.
