Since the news broke out last week, we at Silex have been working to assess the scope of its impact and a plan on how to provide our customers a solution to this WPA2 security issue. This update is to inform our customers the results of our investigation and a preliminary plan on next steps.
Our investigation has shown that:
Wi-Fi Enterprise Security is critical to Silex as we strive to provide secure, reliable and robust wireless connectivity solutions to our customers. We want to assure our customers that we are well aware of the recent KRACK attack threat to WPA2 Wi-Fi security, and we will be providing a solution imminently.
Recently published research in below references have identified vulnerabilities in some Wi-Fi devices. Those devices reinstall network encryption keys under certain conditions, disabling replay protection and significantly reducing the security of encryption. This security vulnerability is inherent to the WPA2 protocol itself, and in principle impacts all products using the WPA security supplicant.
Few weeks ago I wrote a blog post about developing an ath10k patch to support the SDIO Wi-Fi interface for QCA9377-3 WiFi SoC from Qualcomm Technologies. I am happy to report that we have completed this development and the patch has been submitted to be upstreamed into the mainline Linux kernel. This patch is now available for download. We tested this patch with our SX-SDCAC SDIO Wi-Fi + BT Module and an i.MX6SoloX Platform.
Silex Technology, a global leader in wired and wireless networking solutions, today launched LB-100AN which is a Linux Box with Wireless 802.11a/b/g/n for custom application development. It is a box product with Linux OS for embedded applications,
which supports wired and wireless LANs. LB-100AN's hardware support that comes a with development kit which empower the customers to customize their services and applications by themselves to their products. By allowing them to devote themselves to their application development, it minimizes initial hardware development investment, driver development costs and reduces time to market.
Our SX-SDCAC which is in a SD card form factor (using the SX-SDMAC) is designed to allow evaluation of our QCA9377 based radios (SX-SDMAC and SX-SDPAC)) with the NXP's i.MX 6 SoloX Sabre SD board. To go with the hardware we also provide an evaluation software to make the evaluation process easy for our customers.
We have just released an update to our evaluation software.
Summary of Updates:
We have updated to support Linux kernel version 4.1. The most important enhancement in this release is the addition of roaming support. We in our internal testing had found that roaming was not working well in the QCA reference driver. Silex being a QCA partner has access to the radio firmware source code which enables us to fix bugs and in some cases even add features to the driver. Our reference driver now supports roaming with roam times under 150msec.
The evaluation image includes the Silex reference radio driver (with roaming support), supplicant and tools to test the following:
- Basic Wireless Functionality
- Advanced Wi-Fi Security
- Data Throughput
- Soft Access Point Mode
- DHCP Server and Client
Yes it can, and is now Available from Silex!!!
The Silex SX-SDMAC Plus is a dual-band IEEE802.11a/b/g/n/ac WLAN plus Bluetooth 4.2 SDIO module. It is the latest addition to our QCA9377 product family. This latest module is optimized for cost, size and performance. This module makes it a very viable option for customers who want to take advantage of the higher 802.11ac performance at a lower cost and smaller overall footprint.
As the world today migrates to digital era, education and learning is no exception. Classrooms are becoming more digital these days from traditional chalk and talk. Today's Digital Interactive Classroom requires a robust network infrastructure to utilize new technology. This new way of teaching will change our traditional approach towards education and will help both schools and students to gain a competitive edge globally. The set-up includes a giant Interactive White Board or an All-in-one HD Touch-screen LCD, a super-fast desktop or a laptop or tablet and other personalized device .

Taiwan NCC Radio Regulation changes
With the improvement in technology, wireless products range has increased, that includes wireless technologies like WiFi, Bluetooth, and various wireless electronic devices. The Taiwan National communications commission (NCC) demands approval and qualifying certification for radio-frequency equipment to ensure safe and steady operation of the devices. All products able to connect to the public switched communications network, and products emitting radio frequency require approval and registration before they can be sold in Taiwan. This requirement comes from the national body of communications in Taiwan (NCC).
There are few changes in the NCC certification, which are as below,
- Any change to descriptions of accreditation certificate, except for the addition or removal of test category, certification type and certification item mentioned in the preceding paragraph, shall be reported to NCC for resistance within 15 days after the change; the original accreditation certificate shall be attached when reporting the change. The validity of the reissued accreditation certificate shall be the same as the original one.
- Printing NCC logo is mandatary on both the product and the package. It is to be noted that earlier, it was printed only on the product
- Products which has already passed NCC certifications are not affected or need no change. However, from September 6th 2017, the changes in NCC comes applicable for new products
Taiwan ROHS becomes part of the BSMI certification
