CRYSTALS-Kyber is one of the public-key algorithms currently recommended by NIST as part of its post-quantum cryptography standardization process. Researchers have just published a side-channel attack—using power consumption—against an implementation of the algorithm that was supposed to be resistant against that sort of attack. The algorithm is …
Amazon Relational Database Service (Amazon RDS) makes it simpler to set up, operate, and scale a relational database in the AWS Cloud. AWS Secrets Manager helps you manage, retrieve, and rotate database credentials, API keys, and other secrets. Amazon RDS now offers integration with Secrets Manager to manage master …
This is a neat piece of historical research. The team of computer scientist George Lasry, pianist Norbert Biermann and astrophysicist Satoshi Tomokiyo—all keen cryptographers—initially thought the batch of encoded documents related to Italy, because that was how they were filed at the Bibliothèque Nationale de France. However …
The field of machine learning (ML) security—and corresponding adversarial ML—is rapidly advancing as researchers develop sophisticated techniques to perturb, disrupt, or steal the ML model or data. It’s a heady time; because we know so little about the security of these systems, there are many opportunities …
A group of Chinese researchers have just published a paper claiming that they can—although they have not yet done so—break 2048-bit RSA. This is something to take seriously. It might not be correct, but it’s not obviously wrong. We have long known from Shor’s algorithm …
AWS Certificate Manager (ACM) is a managed service that enables you to provision, manage, and deploy public and private SSL/TLS certificates that you can use to securely encrypt network traffic. You can now use ACM to request Elliptic Curve Digital Signature Algorithm (ECDSA) certificates and associate the certificates …
My personal definition of a brilliant idea is one that is immediately obvious once it’s explained, but no one has thought of it before. I can’t believe that no one has described this taxonomy of access control before Eyal Ittay laid it out in this paper. The …
Quantum computing is a completely new paradigm for computers. A quantum computer uses quantum properties such as superposition, which allows a qubit (a quantum bit) to be neither 0 nor 1, but something much more complicated. In theory, such a computer can solve problems too complex for conventional computers …
SIKE is one of the new algorithms that NIST recently added to the post-quantum cryptography competition. It was just broken, really badly. We present an efficient key recovery attack on the Supersingular Isogeny Diffie-Hellman protocol (SIDH), based on a “glue-and-split” theorem due to Kani. Our attack exploits the …

NIST’s post-quantum computing cryptography standard process is entering its final phases. It announced the first four algorithms: For general encryption, used when we access secure websites, NIST has selected the CRYSTALS-Kyber algorithm. Among its advantages are comparatively small encryption keys that two parties can exchange easily, as well …
We are excited to offer hybrid post-quantum TLS with Kyber for AWS Key Management Service (AWS KMS) and AWS Certificate Manager (ACM). In this blog post, we share the performance characteristics of our hybrid post-quantum Kyber implementation, show you how to configure a Maven project to use it, and …
Nadiya Kostyuk and Susan Landau wrote an interesting paper: “ Dueling Over DUAL_EC_DRBG: The Consequences of Corrupting a Cryptographic Standardization Process “: Abstract: In recent decades, the U.S. National Institute of Standards and Technology (NIST), which develops cryptographic standards for non-national security agencies of the U.S. government, has emerged …
Two bills attempting to reduce the power of Internet monopolies are currently being debated in Congress: S. 2992, the American Innovation and Choice Online Act ; and S. 2710, the Open App Markets Act. Reducing the power to tech monopolies would do more to “fix” the Internet than any other …
Hertzbleed is a new side-channel attack that works against a variety of microprocressors. Deducing cryptographic keys by analyzing power consumption has long been an attack, but it’s not generally viable because measuring power consumption is often hard. This new attack measures power consumption by measuring time, making it …
Cruddy cryptography means victims whose files have been encrypted by the Ukraine-tormenting ransomware can break the chains without paying extortionists. [...]
Researchers have found a major encryption flaw in 100 million Samsung Galaxy phones. From the abstract: In this work, we expose the cryptographic design and implementation of Android’s Hardware-Backed Keystore in Samsung’s Galaxy S8, S9, S10, S20, and S21 flagship devices. We reversed-engineered and provide a detailed …
Joan Feigenbaum Amazon Scholar, AWS Cryptography Bill Horne Principal Product Manager, AWS Cryptography AWS Cryptography tools and services use a wide range of encryption and storage technologies that can help customers protect their data both at rest and in transit. In some instances, customers also require protection of their …
Researchers have calculated the quantum computer size necessary to break 256-bit elliptic curve public-key cryptography: Finally, we calculate the number of physical qubits required to break the 256-bit elliptic curve encryption of keys in the Bitcoin network within the small available time frame in which it would actually pose …
I have long been annoyed that the word “crypto” has been co-opted by the blockchain people, and no longer refers to “cryptography.” I’m not the only one. [...]
