Qualcomm’s Snapdragon 820 processor gets technology to secure Android phones

/in

Qualcomm is promising to improve security and privacy on high-end smartphones with Snapdragon Smart Protect, which uses on-device machine learning to help detect zero-day malware.

The popularity of smartphones has started to catch the imagination of hackers, resulting in the need for better protection. Qualcomm’s latest contribution is Snapdragon Smart Protect, which the company announced on Monday.

Smart Protect looks at what’s going on in the smartphone and warns about what it thinks are abnormal behaviors to protect users. At its most basic, that could be an application that takes a photo even though the display is off or an application sending an SMS without any user interaction.

Startup finds malware intrusions by keeping an eye on processor radio frequencies

/in

PFP Cybersecurity, a startup with roots in academia and the military, seeks out malware by analyzing the performance of hardware – not software and not the behavior of devices on the network.

PFP’s system compares ongoing radio-frequency output from processors to a baseline that is established when the device is known to be performing legitimate tasks. When it detects anomalies that might represent malicious activity, it triggers alarms. Then it’s up to other tools to figure out what exactly is behind the problem.

The system could be used to keep an eye on a large number of similar devices all performing the same task, such as those found in supervisory control and data acquisition (SCADA) networks that support power grids, chemical plants and the like. Savannah River National Laboratory is considering the gear for to protect its smart-grid relays.

AMD reveals its first ARM processor: 8-core Opteron A1100

/in

AMD announced plans to build ARM server CPUs back in 2012. Today the company took a big step towards making those chips a reality, announcing that an 8-core ARM System-on-Chip would begin sampling in March.

Codenamed “Seattle,” the processors will be branded Opteron A-series and built on a 28 nm process. The first of these will be the A1100. This will have 4 or 8 cores based on ARM’s Cortex-A57 design. This is a high performance, 64-bit ARM core, and it will run at clock speeds of at least 2 GHz. The chips will have up to 4MB of level 2 cache and 8MB of level 3 cache, with both caches shared across all the cores. They’ll support dual channel DDR3 or DDR4, with up to 128GB RAM. The chips will also include a bunch of connectivity: eight PCIe 3 lanes, eight SATA 3 ports, and two 10 Gigabit Ethernet ports. Rounding out the SoCs, they’ll also include dedicated engines for cryptography and compression. The whole thing has an expected power usage of 25W.

While these chips are aimed at high density, low power servers, AMD is also putting together a micro-ATX development kit built around the A1100. This will include a Fedora-based Linux environment with development tools, Apache, MySQL, PHP, and Java 7 and 8.  This software stack is consistent with the goals of these low power servers: running Web applications is likely to be their primary role.
