11. A machine-readable non-transitory storage medium having instructions therein, which when executed by a machine, cause the machine to perform a method, the method comprising: providing a source code specifying operations in a programming language, wherein machine instructions are executable to perform the operations specified in the source code; and emitting a code stream as compiled code for compiling the source code based on the machine instructions, wherein a portion of the compiled code has been emitted, wherein a next portion of the compiled code is to be emitted from a next code of the machine instructions, the code stream having an amount of randomization to protect against execution of potential un-trusted executable instructions embedded via the source code, wherein the emitting the code stream comprises: determining if the next code from the machine instructions is trusted or not, if the next code is not trusted, randomly determining whether to select the next code for randomization to allow adjustment of the amount of randomization in the code stream, if the next code is selected for randomization, performing randomization operations on the next code to introduce additional randomness to the code stream, wherein the randomization operations are performed on the next code before completion of the compilation of the source code, and emitting the randomized next code to the code stream for execution.

The medium of claim 11 , wherein the randomization operations include constant blinding operations.
