Abstract
A method and apparatus for updating a checksum of a data structure wherein the checksum has an additive property. According to the invention, a word value of a word that is to be modified is eliminated from a checksum to form a current checksum. The current checksum is then updated with a modified word value of a modified word. A system for data structures includes a computer readable and writeable medium and a processor which performs the method of the invention.
