Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for verifying a message based on application of a hashing algorithm. In one aspect, a method includes identifying a file and a key value and processing the file using multiple nonlinear functions to generate an output hash value, where the operations performed by the nonlinear functions are modified based on the key value. The file can then be verified based on the output hash value.
