Adding TPM 2.0 to an embedded product usually starts with a hardware question: where does the security chip go? On Variscite’s i.MX-based modules, there is now another answer. Variscite and SecEdge are bringing SecEdge’s TPM 2.0 firmware, anchored in the processor’s own security hardware, to Variscite’s i.MX System on Module portfolio.
