Google’s Tensor G6 Rumored to Be Paired with New Titan M3 Security Coprocessor

Why It Matters

A more robust Titan M3 would strengthen Pixel’s security posture, potentially differentiating the brand in a crowded smartphone market and reinforcing Google’s reputation for privacy‑focused hardware.

Key Takeaways

• Titan M3 slated for Tensor G6 “Google Epic”.
• Firmware codename “longjing” indicates early development stage.
• Aims to rival Apple Secure Enclave in security.
• Enhances protection against side‑channel attacks.
• Could boost Pixel’s market positioning amid competition.

Pulse Analysis

Google’s push for a new Titan M3 security coprocessor reflects a broader industry trend toward hardware‑based trust anchors. Since the original Titan M debuted in 2018, Google has layered increasingly sophisticated defenses—bootloader verification, StrongBox key storage, and resistance to electromagnetic and laser attacks. By integrating Titan M3 with the upcoming Tensor G6, Google signals intent to embed deeper, tamper‑resistant capabilities directly into the silicon, moving beyond software patches to a more immutable security foundation.

The rumored “longjing” firmware and “Google Epic” codename suggest a focused effort to match, if not exceed, Apple’s Secure Enclave. While Apple’s enclave has long been a benchmark for on‑device encryption and biometric protection, Titan M3 could introduce advanced countermeasures such as real‑time side‑channel monitoring and hardware‑isolated AI model verification. Such features would not only harden Pixel phones against emerging threats like fault injection but also enable new use cases—secure on‑device AI inference, encrypted credential vaults, and more granular app sandboxing—thereby expanding Google’s ecosystem control.

From a business perspective, a fortified Titan M3 could revitalize Pixel’s value proposition amid declining market share. Security‑savvy consumers and enterprise clients increasingly prioritize devices with proven hardware trust, and Google’s ability to market a “Google‑grade” secure chip may attract premium buyers and differentiate Pixel from Android OEMs relying on third‑party solutions. Moreover, a robust security narrative aligns with Google’s broader privacy commitments, potentially opening doors for partnerships in regulated sectors such as finance and healthcare, where hardware‑level compliance is a prerequisite.

Google’s Tensor G6 rumored to be paired with new Titan M3 security coprocessor

Google initially debuted its Titan M security chip back in 2018 with the Pixel 3 before following it up with Titan M2 in its first‑gen Tensor launch. Now, as we approach the tenth anniversary of Pixel and the five‑year anniversary of that step into custom silicon, Google is rumored to be working on yet another step forward for its security coprocessor.

As reported by Mystic Leaks on Telegram, Google is apparently working on Titan M3 for this year’s Tensor G6, codenamed “Google Epic,” running firmware “longjing.” There’s not much else to go off of here other than these initial internal listings, though this leaked report suggests Google is aiming to compete more directly with Apple’s Secure Enclave. It’s certainly been a while since we’ve seen a fresh Titan M‑series coprocessor, and whatever anniversary plans the company has in store for Pixel this year seem to suggest this is as good a time as any for a refresh.

But as for what to expect, all we can really do is speculate using past information. The blog post for Google’s initial Titan launch points to a handful of ways it’s designed to protect your phone, including bootloader validation, lock‑screen protection through a limited series of login attempts, and the ability to “generate and store” private keys through the then‑new StrongBox KeyStore API launched with Android 9. When Google launched the RISC‑V‑based Titan M2 chip alongside Tensor, it promoted protection against “electromagnetic analysis, voltage glitching, and even laser fault injection.”

Google has certainly seen a handful of Pixel vulnerabilities over the last half‑decade, though it’s been able to fix most (if not all) of them through monthly security patches. Whether Titan M3 brings improvements to that front — or, perhaps, goes for more out‑there targets like the M2’s laser‑fault‑injection protection — remains to be seen. Either way, it’s shaping Tensor G6 up to be an interesting launch, and one that could help the brand during otherwise unsteady times.
