Homomorphic Polynomial Public Key Cryptography for Quantum-secure Digital Signature
In their 2022 study, Kuang et al. introduced Multivariable Polynomial Public Key (MPPK) cryptography, leveraging the inversion relationship between multiplication and division for quantum-safe public key systems. They extended MPPK into Homomorphic Polynomial Public Key (HPPK), employing homomorphic encryption for large hidden ring operations. Originally designed for key encapsulation (KEM), HPPK's security relies on homomorphic encryption of public polynomials. This paper expands HPPK KEM to a…

A Solution for Commercializing, Decentralizing and Storing Electronic Medical Records by Integrating Proxy Re-Encryption, IPFS, and Blockchain
The rapid expansion of user medical records across global systems presents not only opportunities but also new challenges in maintaining effective application models that ensure user privacy, controllability, and the ability to commercialize patient medical records. Moreover, the proliferation of data analysis models in healthcare institutions necessitates the decentralization and restorability of medical record data. It is imperative that user medical data collected from these systems can be e…

«📣Official statement: the new EU chat controls proposal for mass scanning is the same old surveillance with new branding.
Whether you call it a backdoor, a front door, or “upload moderation” it undermines encryption & creates significant vulnerabilities.»

Understanding crypter-as-a-service in a popular underground marketplace
Crypters are pieces of software whose main goal is to transform a target binary so it can avoid detection from Anti Viruses (AVs from now on) applications. They work similar to packers, by taking a malware binary and applying a series of modifications, obfuscations and encryptions to output a binary that evades one or more AVs. The goal is to remain fully undetected, or FUD in the hacking jargon, while maintaining its (often malicious) functionality. In line to the growth of commoditization in …

We give thanks to all those that produced the proofs and the persistence to get this win against the Machine and Recall made opt-in with separate encryption of the database.
Sincere thanks.
But this is the opening salvo. Recall is a shabby and amateurish thing. Product fiddling around the outside of the code and slathering encryption on the storage makes no purse out of this Pig's Ear.
It's fundamentally a broken idea and needs burying.

EncCluster: Scalable Functional Encryption in Federated Learning through Weight Clustering and Probabilistic Filters
Federated Learning (FL) enables model training across decentralized devices by communicating solely local model updates to an aggregation server. Although such limited data sharing makes FL more secure than centralized approached, FL remains vulnerable to inference attacks during model update transmissions. Existing secure aggregation approaches rely on differential privacy or cryptographic schemes like Functional Encryption (FE) to safeguard individual client data. However, such strategies can…

Time to Separate from StackOverflow and Match with ChatGPT for Encryption
Cryptography is known as a challenging topic for developers. We studied StackOverflow posts to identify the problems that developers encounter when using Java Cryptography Architecture (JCA) for symmetric encryption. We investigated security risks that are disseminated in these posts, and we examined whether ChatGPT helps avoid cryptography issues. We found that developers frequently struggle with key and IV generations, as well as padding. Security is a top concern among developers, but securi…
