Rambus Unveils Quantum Safe Engines to Shield Data in Post-Quantum Era

Quantum ComputingQuantum Safe Engines (QSEs) from Rambus are now available for integration into hardware security components in ASICs, SoCs, and FPGAs. The asymmetric encryption that is now in place will be broken by adversaries using quantum computers, endangering valuable assets and data, according to Rambus. Protecting government and critical data center hardware against attacks that arise in the post-quantum computing age is the goal of the Rambus QSE IP core, which employs quantum-resistant algorithms chosen by NIST.

“Our everyday applications, ranging from artificial intelligence to email and streaming video, depend on data integrity and need to be protected against the increasing threat of attacks made possible by quantum computers,” said Neeraj Paliwal, General Manager of Silicon IP at Rambus. “We are assisting customers in their transition to quantum safe cryptography today with the addition of the Rambus Quantum Safe Engine to our security intellectual property portfolio.”

The research manager of Quantum Computing Research at IDC, Heather West, PhD, stated that “Quantum computers will provide individuals and organizations the exponential speed-up and compute power needed to solve some of today’s most complex problems, including the ability to decrypt current data encryption algorithms. To safeguard their historical, present, and future data against assaults made possible by quantum computing, companies must immediately implement quantum-resistant encryption.”

Asymmetric Encryption

For a complete hardware security solution, the Rambus QSE IP may be purchased alone as a cryptographic core or together with the Rambus Quantum Safe Root of Trust IP. Together with SHA-3, SHAKE-128, and SHAKE-256 acceleration, it supports the National Institute of specifications and Technology’s (NIST) proposed specifications for quantum-resistant algorithms (FIPS 203 ML-KEM and FIPS 204 ML-DSA). An extra DPA version of the QSE IP is provided for highly secure applications that need protection against DPA assaults. Licensing for the Rambus QSE is now available.

Asymmetric encryption is a data encryption technique that uses two mathematically related keys to encrypt data: a public key and a private key. To encrypt data, the public key is made available to everybody. On the other hand, the owner keeps the private key a secret and uses it to decrypt data. This technique nowadays offers a secure method of data transmission by guaranteeing that a message encrypted with an individual’s public key can only be decoded with their private key. Many digital security methods, including those protecting credit card transactions and private conversations, are based on asymmetric encryption. Moreover, it offers the framework for digital signatures, which confirm the legitimacy of a communication or document.

The main risk of asymmetric encryption in the post-quantum computing era is that quantum computers will be able to solve the mathematical puzzles that present current encryption techniques. Because quantum computers can do several operations at once, they are particularly good at factoring huge numbers and solving discrete logarithms, which is the foundation of asymmetric algorithms like RSA and ECC.
