Abstract
A system, a method and a computer program product for protecting a speculative execution processor from side channel attacks, are disclosed. The system comprises a processing circuitry which performs an execution of a code segment, in one time period and copies, in another time period, only a committed portion of the executed code segment into a memory component which is accessible to read actions by an external processing unit. The speculative instructions are stored in an internal cache memory which is not accessible to read actions by the external processing unit.
