Google initially debuted its Titan M safety chip again in 2018 with the Pixel 3 earlier than following it up with Titan M2 in its first-gen Tensor launch. Now, as we strategy the tenth anniversary of Pixel and the five-year anniversary of that step into customized silicon, Google is rumored to be engaged on yet one more step ahead for its safety coprocessor.
As reported by Mystic Leaks on Telegram, Google is seemingly engaged on Titan M3 for this yr’s Tensor G6, codenamed “Google Epic,” working firmware “longjing.” There’s not a lot else to go off of right here apart from these preliminary inner listings, although this leaked report suggests Google is aiming to compete extra instantly with Apple’s Safe Enclave. It’s definitely been some time since we’ve seen a recent Titan M-series coprocessor, and no matter anniversary plans the corporate has in retailer for Pixel this yr appears to recommend that is pretty much as good a time as any for a refresh.
However as for what to anticipate, all we are able to actually do is speculate utilizing previous data. The blog post for Google’s initial Titan launch factors to a handful of the way it’s designed to guard your telephone, together with bootloader validation, lock display screen safety by a restricted sequence of login makes an attempt, and the power to “generate and retailer” personal keys by the then-new StrongBox KeyStore API launched with Android 9. When Google launched the RISC-V-based Titan M2 chip alongside Tensor, it promoted safety in opposition to “electromagnetic evaluation, voltage glitching, and even laser fault injection.”
Google has definitely seen a handful of Pixel vulnerabilities over the past half-decade, although it’s been in a position to repair most (if not all) of them by month-to-month safety patches. Whether or not Titan M3 brings enhancements to that entrance — or, maybe, goes for extra out-there targets just like the M2’s laser fault injection safety — stays to be seen. Both method, it’s shaping Tensor G6 as much as be an fascinating launch, and one that might assist the model throughout in any other case unsteady occasions.
