Apple Unveils PQ3 Protocol - Post-Quantum Encryption for iMessage

Apple Unveils PQ3 Protocol - Post-Quantum Encryption for iMessage

Feb 22, 2024 Quantum Computing / Encryption
Apple has announced a new post-quantum cryptographic protocol called  PQ3  that it said will be integrated into iMessage to secure the messaging platform against future attacks arising from the threat of a practical quantum computer. "With compromise-resilient encryption and extensive defenses against even highly sophisticated quantum attacks, PQ3 is the first messaging protocol to reach what we call Level 3 security — providing protocol protections that surpass those in all other widely deployed messaging apps," Apple  said . The iPhone maker described the protocol as "groundbreaking," "state-of-the-art," and as having the "strongest security properties" of any cryptographic convention deployed at scale. PQ3 is the latest security guardrail erected by Apple in iMessage after it switched from  RSA  to Elliptic Curve cryptography ( ECC ), and by protecting encryption keys on devices with the Secure Enclave in 2019. While the current algorith

ÆPIC and SQUIP Vulnerabilities Found in Intel and AMD Processors

Aug 16, 2022
A group of researchers has revealed details of a new vulnerability affecting Intel CPUs that enables attackers to obtain encryption keys and other secret information from the processors. Dubbed  ÆPIC Leak , the weakness is the first-of-its-kind to architecturally disclose sensitive data in a manner that's akin to an "uninitialized memory read in the CPU itself." "In contrast to transient execution attacks like  Meltdown and Spectre ,  ÆPIC Leak  is an architectural bug: the sensitive data gets directly disclosed without relying on any (noisy) side channel," the academics said. The study was conducted by researchers from the Sapienza University of Rome, the Graz University of Technology, Amazon Web Services, and the CISPA Helmholtz Center for Information Security. The vulnerability ( CVE-2022-21233 , CVSS score: 6.0), which affects CPUs with Sunny Cover microarchitecture, is rooted in a component called Advanced Programmable Interrupt Controller ( APIC ), wh

6 Ways to Simplify SaaS Identity Governance

Feb 21, 2024SaaS Security / Identity Management
With SaaS applications now making up the vast majority of technology used by employees in most organizations, tasks related to identity governance need to happen across a myriad of individual SaaS apps. This presents a huge challenge for centralized IT teams who are ultimately held responsible for managing and securing app access, but can't possibly become experts in the nuances of the native security settings and access controls for hundreds (or thousands) of apps. And, even if they could, the sheer volume of tasks would easily bury them. Modern IT teams need a way to orchestrate and govern SaaS identity governance by engaging the application owners in the business who are most familiar with how the tool is used, and who needs what type of access.  Nudge Security is a  SaaS security and governance solution  that can help you do just that, with automated workflows to save time and make the process manageable at scale. Read on to learn how it works. 1 . Discover all SaaS apps used b
