GPUs are vulnerable to side-channel attacks

Published on 13th November, 2018, 6:55 PM

Computer scientists at the University of California at Riverside have found that GPUs are vulnerable to side-channel attacks, the same kinds of exploits that have impacted Intel and AMD CPUs.

Two professors and two students, one a computer science doctoral student and a post-doctoral researcher, reverse-engineered a Nvidia GPU to demonstrate three attacks on both graphics and computational stacks, as well as across them. The researchers believe these are the first reported side-channel attacks on GPUs.

A side-channel attack is one where the attacker uses how a technology operates, in this case a GPU, rather than a bug or flaw in the code. It takes advantage of how the processor is designed and exploits it in ways the designers hadn’t thought of.

Making the right hyperconvergence choice: HCI hardware or software?

Published on 12th November, 2018, 11:00 AM

Once a niche technology, primarily attractive to organizations with specific needs, such as streamlining operations at branch offices, hyperconverged infrastructure (HCI) is rapidly finding a wide customer base.

HCI is an IT framework that combines storage, computing and networking into a single system; hyperconverged platforms include a hypervisor for virtualized computing, software-defined storage, and virtualized networking.

Enterprises planning an HCI adoption can select from two main approaches: hardware or software. HCI hardware typically comes in the form of an integrated appliance, a hardware/software package created and delivered by a single vendor. Appliance vendors include Dell EMC, Nutanix and HPE/SimpliVity. A software-only offering allows customers to deploy HCI on a bring-your-own-technology basis. HCI software vendors include Maxta and VMware (vSAN).

What is Transport Layer Security (TLS)?

Published on 9th November, 2018, 5:31 PM

Despite the goal of keeping Web communications private, flaws in the design and implementation of Transport Layer Security have led to breaches, but the latest version – TLS 1.3 – is an overhaul that strengthens and streamlines the crypto protocol.

What is TLS?

TLS is a cryptographic protocol that provides end-to-end communications security over networks and is widely used for internet communications and online transactions. It is an IETF standard intended to prevent eavesdropping, tampering and message forgery. Common applications that employ TLS include Web browsers, instant messaging, e-mail and voice over IP.
