NCSC Guidance on “Advanced Cryptography”

The UK's National Cyber Security Centre just released its white paper on "Advanced Cryptography," which it defines as "cryptographic techniques for processing encrypted data, providing enhanced functionality over and above that provided by traditional cryptography." It includes things like...

AI-Based Crypto Tokens: the Illusion of Decentralized AI?

The convergence of blockchain and artificial intelligence AI has led to the emergence of AI-based tokens, which are cryptographic assets designed to power decentralized AI platforms and services. This paper provides a comprehensive review of leading AI-token projects, examining their technical...

Federated One-Shot Learning with Data Privacy and Objective-Hiding

Privacy in federated learning is crucial, encompassing two key aspects: safeguarding the privacy of clients' data and maintaining the privacy of the federator's objective from the clients. While the first aspect has been extensively studied, the second has received much less attention. We present...

ScaloWork: Useful Proof-Of-Work with Distributed Pool Mining

Bitcoin blockchain uses hash-based Proof-of-Work PoW that prevents unwanted participants from hogging the network resources. Anyone entering the mining game has to prove that they have expended a specific amount of computational power. However, the most popular Bitcoin blockchain consumes 175.87...

Measuring Computational Universality of Fully Homomorphic Encryption

Many real-world applications, such as machine learning and graph analytics, involve combinations of linear and non-linear operations. As these applications increasingly handle sensitive data, there is a significant demand for privacy-preserving computation techniques capable of efficiently...

CVE-2025-21898

In the Linux kernel, the following vulnerability has been resolved: ftrace: Avoid potential division by zero in functionstatshow Check whether denominator expression x x - 1 1000 mod 2^32, 2^64 produce zero and skip stddev computation in that case. For now don't care about rec-counter rec-counter...

AIs as Trusted Third Parties

This is a truly fascinating paper: "Trusted Machine Learning Models Unlock Private Inference for Problems Currently Infeasible with Cryptography." The basic idea is that AIs can act as trusted third parties: Abstract: We often interact with untrusted parties. Prioritization of privacy can limit t...

CVE-2023-52933

In the Linux kernel, the following vulnerability has been resolved: Squashfs: fix handling and sanity checking of xattrids count A Sysbot 1 corrupted filesystem exposes two flaws in the handling and sanity checking of the xattrids count in the filesystem. Both of these flaws cause computation...

CVE-2023-52933

CVE-2023-52933 affects the Linux kernel Squashfs xattr_ids handling. Two overflow flaws were exposed by a corrupted filesystem: on 64‑bit systems, sign extension of xattr_ids when multiplied by sizeof(struct squashfs_xattr_id) can overflow and yield an incorrect len; on 32‑bit systems, the unsign...

CVE-2025-1673

CVE-2025-1673 affects Zephyr RTOS with a vulnerability in DNS packet handling. Multiple connected sources describe an out-of-bounds read triggered by a malicious or malformed DNS packet without a payload, potentially causing a crash (DoS) or incorrect computation. The CVE entry references an issu...

GHSA-F8QM-HMM3-FV7F Namada-apps allows Excessive Computation in Mempool Validation

Impact A malicious transaction may cause an expensive computation in mempool validation. A transaction with multiple repeated sections causes the section hash calculation used for signature validation to grow exponentially and potentially even cubic in proportion to number of sections. This may b...
