This isn’t good: On Thursday, researchers from security firm Binarly revealed that Secure Boot is completely compromised on more than 200 device models sold by Acer, Dell, Gigabyte, Intel, and Supermicro. The cause: a cryptographic key underpinning Secure Boot on those models that was compromised in 2022. In a public GitHub repository committed in December … Read More “Compromising the Secure Boot Process” »

Model Extraction from Neural Networks

A new paper, “Polynomial Time Cryptanalytic Extraction of Neural Network Models,” by Adi Shamir and others, uses ideas from differential cryptanalysis to extract the weights inside a neural network using specific queries and their results. This is much more theoretical than practical, but it’s a really interesting result. Abstract: Billions of dollars and countless GPU … Read More “Model Extraction from Neural Networks” »

Quantum computers are probably coming, though we don’t know when—and when they arrive, they will, most likely, be able to break our standard public-key cryptography algorithms. In anticipation of this possibility, cryptographers have been working on quantum-resistant public-key algorithms. The National Institute for Standards and Technology (NIST) has been hosting a competition since 2017, and … Read More “Lattice-Based Cryptosystems and Quantum Cryptanalysis” »

New Lattice Cryptanalytic Technique

A new paper presents a polynomial-time quantum algorithm for solving certain hard lattice problems. This could be a big deal for post-quantum cryptographic algorithms, since many of them base their security on hard lattice problems. A few things to note. One, this paper has not yet been peer reviewed. As this comment points out: “We … Read More “New Lattice Cryptanalytic Technique” »

Ross Anderson unexpectedly passed away Thursday night in, I believe, his home in Cambridge. I can’t remember when I first met Ross. Of course it was before 2008, when we created the Security and Human Behavior workshop. It was well before 2001, when we created the Workshop on Economics and Information Security. (Okay, he created … Read More “Ross Anderson” »

Improving Shor’s Algorithm

We don’t have a useful quantum computer yet, but we do have quantum algorithms. Shor’s algorithm has the potential to factor large numbers faster than otherwise possible, which—if the run times are actually feasible—could break both the RSA and Diffie-Hellman public-key algorithms. Now, computer scientist Oded Regev has a significant speed-up to Shor’s algorithm, at … Read More “Improving Shor’s Algorithm” »
