Mobile software authentication and validation

摘要

Methods for encoding and validating a computer program are disclosed. A program is encoded by transforming the program using a canonical transform based at least in part on a partitioning algorithm, creating an encrypted hash value based at least on the transformed program and an encryption key, and embedding the encrypted hash value in the transformed program. A program embedded with the encrypted hash value is validated by receiving the program embedded with the encrypted hash value, transforming the program embedded with the encrypted hash value using a canonical transform based at least in part on a partitioning algorithm; comparing the received program and the transformed program to extract a first encrypted hash value, creating a second encrypted hash value-based at least on the transformed program and an encryption key, and validating the program responsive to the first and second encrypted hash values.
