FrodoPIR: New Privacy-Focused Database Querying System

FrodoPIR: New Privacy-Focused Database Querying System

Dec 23, 2022 Encryption / Privacy / Browser
The developers behind the Brave open-source web browser have revealed a new privacy-preserving data querying and retrieval system called  FrodoPIR . The idea, the company  said , is to use the technology to build out a wide range of use cases such as safe browsing, scanning passwords against breached databases, certificate revocation checks, and streaming, among others. The scheme is called  FrodoPIR  because "the client can perform hidden queries to the server, just as Frodo remained hidden from Sauron," a reference to the characters from J. R. R. Tolkien's  The Lord of the Rings . PIR, short for  private information retrieval , is a cryptographic protocol that enables users (aka clients) to retrieve a piece of information from a database server without revealing to its owner which element was selected. In other words, the goal is to be able to query a platform for information (say, cooking videos) without letting the service provider infer from...
Researchers Demonstrate New Side-Channel Attack on Homomorphic Encryption

Researchers Demonstrate New Side-Channel Attack on Homomorphic Encryption

Mar 03, 2022
A group of academics from the North Carolina State University and Dokuz Eylul University have demonstrated what they say is the "first side-channel attack" on homomorphic encryption that could be exploited to leak data as the encryption process is underway. "Basically, by monitoring power consumption in a device that is encoding data for homomorphic encryption, we are able to read the data as it is being encrypted," Aydin Aysu, one of the authors of the study,  said . "This demonstrates that even next generation encryption technologies need protection against side-channel attacks." Homomorphic Encryption is a  form of encryption  that allows certain types of computation to be performed directly on encrypted data without having to decrypt it in the first place. It's also meant to be privacy-preserving in that it allows sharing of sensitive data with other third-party services, such as data analytics firms, for further processing while the underlyin...
The Evolving Role of PAM in Cybersecurity Leadership Agendas for 2025

The Evolving Role of PAM in Cybersecurity Leadership Agendas for 2025

Feb 06, 2025AI Security / Cybersecurity
Privileged Access Management (PAM) has emerged as a cornerstone of modern cybersecurity strategies, shifting from a technical necessity to a critical pillar in leadership agendas. With the PAM market projected to reach $42.96 billion by 2037 (according to Research Nester), organizations invest heavily in PAM solutions. Why is PAM climbing the ranks of leadership priorities? While Gartner highlights key reasons such as enhanced security, regulatory compliance readiness, and insurance requirements, the impact of PAM extends across multiple strategic areas. PAM can help organizations enhance their overall operational efficiency and tackle many challenges they face today. To explore more about PAM's transformative impact on businesses, read The Cyber Guardian: PAM's Role in Shaping Leadership Agendas for 2025 by a renowned cybersecurity expert and former Gartner lead analyst Jonathan Care.  What cybersecurity challenges may organizations face in 2025? The cybersecurity landsca...
