Annotation: The complexity of neutralization and the lack of a universal mitigation approach of speculative execution attacks allows potential malware to have an unauthorized access to data being processed by CPU. To provide the confidentiality of such data it`s processing should be transferred from CPU to a microprocessor operating in a trusted execution environment. Paper describes the approach of using Intel DAL technology, which allows to implement application in Intel ME subsystem, thus completely mitigate side channel speculative execution attacks.
