Abstract: Systems and methods for performing cryptographic data processing operations in a manner resistant to external monitoring attacks. An example method may comprise: executing, by a processing device, a first data manipulation instruction, the first data manipulation instruction affecting a state of the processing device; executing a second data manipulation instruction, the second data manipulation instruction interacting with said internal state; and breaking a detectable interaction of the first data manipulation instruction and the second data manipulation instruction by executing a third data manipulation instruction utilizing an unpredictable data item.

Abstract: Embodiments herein facilitate resisting side channel attacks through various implementations and combinations of implementations. In embodiments, this is accomplished by preventing sensitive data from consecutively following other data through potentially vulnerable resources which otherwise may cause data to leak. Where such vulnerabilities to attacks are known, suspected, or as a proactive precaution, a cleaner can be used to inhibit the sensitive data from passing through the vulnerable areas consecutively and thus inhibit the leakage. Embodiments also envision utilizing certain types of circuits to assist in preventing leakage. By using such circuits one can reduce or even potentially eliminate the requirement for cleaners as mentioned previously.
