Abstract
The present invention is a mask ordering method and apparatus which controls the way keys are compared. In its general form, the mask ordering method operates to order (with a less than, greater than or equal to comparison) two N-byte (for example, N=16) keys (Key and Key ) using an N-bit ordering mask where the N bits in the ordering mask correspond one for one with the N bytes in the keys in the same compare direction (either left-to-right or right-to-left).
