Intel and Nvidia embed post-quantum cryptography in server chips

Intel and Nvidia are integrating post-quantum cryptography acceleration into server hardware to counter harvest-now-decrypt-later attacks. Intel expects its Xeon 6 chips to be fully PQC-ready by 2029, while Nvidia is adding post-quantum standards to confidential computing security layers. The move follows NIST's 2024 standardization of post-quantum algorithms.

Key Facts

Intel expects its Xeon 6 server chips to be fully post-quantum cryptography compliant by 2029.
NIST standardized post-quantum cryptography algorithms in 2024 to protect digital signatures and public network data encryption.
Nvidia is implementing post-quantum standards into the security layers of its confidential computing platform.
AES-256 symmetric encryption is considered quantum-resistant, according to Nelly Porter, director of product management for GCP Confidential Computing and Encryption.

Hardware Acceleration

Intel has started providing PQC-capable support in Xeon 6 server hardware chips to protect against quantum computer attacks. Intel plans to protect standard AES Internet traffic with PQC and hardware acceleration by securing handshakes. Nvidia is integrating post-quantum standards into security layers underpinning confidential computing, where trust and attestation are established for secure data exchange. Hardware-based encryption is faster than software techniques, but it typically takes years for hardware makers to implement the technology into their products.

Standardization Timeline

NIST published AES in 2001 and it went into effect in 2002, but it appeared in AMD and Intel chips only in 2010. Post-quantum cryptography is asymmetric and requires a combination of public and private keys, making it structurally resistant to quantum computing attacks. RSA and ECC asymmetric encryption techniques are considered vulnerable to quantum attacks. Intel expects a multi-year journey to transition all of its chips to be PQC-compliant, with new algorithms coexisting with AES to handle both quantum and standard web traffic.

iAuthFlow v2 malware adds attacker passkeys to hijacked email accounts

Security researchers at Abnormal discovered iAuthFlow v2, a malware toolkit sold on Russian forums for over $10,000 that lets attackers regain access to compromised email accounts even after password resets. The tool phishes credentials from Google, Microsoft, iCloud, or LinkedIn, then silently creates an attacker-controlled passkey. Abnormal advises users to audit passkeys, OAuth tokens, mail rules, and remove rogue authentication methods.
