This abstract first appeared for US patent application 20250094567 titled 'Consistent Speculation of Pointer Authentication

==Original Abstract Submitted==

in an embodiment, a processor includes hardware circuitry which may be used to authenticate instruction operands. the processor may execute instructions that perform operand authentication both speculatively and non-speculatively. during speculative execution of such instructions, the processor may execute authentication such that no differences in observable state of the processor, relative to authentication result, are detectable via a side channel. during speculative execution, a result of authentication may be deferred until speculative execution of the instruction, and additional instructions, may be completed. upon resolution of a condition that indicates acceptance of the speculative execution, a speculative execution result may cause a processor exception and stalling of execution at the instruction to be performed.
