METHOD AND SYSTEM FOR PROTECTING EXECUTION OF CRYPTOGRAPHIC HASH FUNCTIONS |
摘要 |
A method of protecting the execution of a cryptographic hash function, such as SHA-256, in a computing environment where inputs, outputs and intermediate values can be observed. The method consists of encoding input messages so that hash function inputs are placed in a transformed domain, and then applying a transformed cryptographic hash function to produce an encoded output digest; the transformed cryptographic hash function implements the cryptographic hash function in the transformed domain. |
