Rambus unveiled its latest innovation in the realm of cybersecurity: the first installment of its Quantum Safe security IP products, featuring the next-generation Root of Trust tailored for fortifying data center and communications security. In an era when the imminent potential of quantum computers threatens to compromise existing asymmetric encryption methods, Rambus is taking proactive measures to safeguard vital data and assets from impending threats.
In an interview with EE Times, Bart Stevens, a marketing executive at Rambus, said this new generation of the Rambus Root of Trust is a flagship first product in the company’s Quantum Safe IP portfolio, offering customers complete security solutions for the data center and advanced workloads like generative AI.
“The Root of Trust core handles platform-security mechanisms, such as secure boot, secure firmware update, secure debug, [Caliptra] platform attestation and authentication, secure personalization, secure provisioning, secure configuration, and feature management, as well as post-boot security and crypto services to data center applications using its crypto accelerators,” Stevens said.
The Rambus Root of Trust IP protects key data center infrastructure and sophisticated AI and machine learning (ML) systems using a post quantum cryptography (PQC)-based hardware security solution. Institutions like the National Institute of Standards and Technology (NIST) helped discover cryptographic algorithms that can withstand a quantum computer’s power in the quest for robust data security.
“The solution offers a CNSA SP 800-208-compliant software and firmware sign/verify and supports the NIST-approved, quantum-resistant algorithms,” Stevens said. “These algorithms replace the classical algorithms and can be used by security applications that need to protect against attacks by quantum computers.”
The increasing potential of quantum computers to swiftly break through conventional asymmetric encryption methods has spurred the need for preemptive security solutions.
Quantum computers’ immense computational power poses a risk to existing cryptographic mechanisms, which necessitates the exploration of alternative approaches to data protection. Rambus is stepping up to this challenge with its Quantum Safe security IP products.
PQC: A paradigm shift
At the heart of Rambus’ response lies the concept of PQC.
PQC represents a new generation of cryptographic algorithms that steer clear of the traditional public key crypto mechanisms, like RSA and Elliptic Curve Cryptography, which are at risk of being compromised by quantum computers. The Rambus Root of Trust RT-600 portfolio, a family of programmable hardware security cores, incorporates PQC to offer a holistic hardware security solution for data center and AI/ML applications.
“Algorithms in this current release are Crystals-Kyber Key Establishment, Crystals-Dilithium Digital Signing, XMSS and LMS stateful hash firmware validation, AES-256 symmetric cipher algorithm and SHA-3/SHAKE secure hashing,” Stevens said.
Fortifying security
Rambus Root of Trust IP strategically integrates quantum-compute–resistant cryptographic algorithms, as recommended by the NIST, according to Stevens.
These algorithms, including CRYSTALS-Kyber for key encapsulation and CRYSTALS-Dilithium for digital signatures, offer an impregnable shield against quantum attacks. The solution also extends its support to the Commercial National Security Algorithm Suite (CNSA) algorithms, ensuring comprehensive software and firmware updates protection.
Balancing performance and efficiency
A noteworthy consideration in cryptographic solutions is the balance between performance and efficiency.
Rambus recognizes this challenge, and it has meticulously designed the Rambus Root of Trust IP to align with the performance and efficiency benchmarks of classical algorithms. This pragmatic approach caters to the current demands of the industry and anticipates the needs of the next generation of silicon.
Implementing the Rambus Root of Trust IP within data centers and AI/ML systems is a streamlined process. The hardware register-transfer-level (HW TRL) and software solution is seamlessly integrated by SoC developers as a security module, connecting natively to host systems’ SoC buses. The solution offers a robust and scalable foundation for organizations looking to fortify their digital fortresses, according to Stevens.
Quantum-safe security for all
The impact of Rambus’ Quantum Safe IP solutions reverberates across industries and sectors. While initially AI training and inference accelerators stand to benefit, future prospects indicate widespread adoption. The technology holds promise for automotive designs and AI edge accelerators, for starters.
“Aside from the CNSA algorithms just released, it is expected that European and Asian standards will emerge with different algorithms,” Stevens said. “Also, NIST has issued a fourth round of candidates for standardization, which may lead to additional algorithms to be required.
“In addition to algorithms, security protocols such as TLS, IPsec, MACsec will have their key establishment and exchange mechanism extended to use the new algorithms,” he added. “Future developments will also encompass adding DPA and fault attack countermeasures, as well as automotive-safety mechanisms.”
