Zymkey Pilot Manufacturing

A closer look at the first security module build

Zymkey-II-USB-Manufacture-10

What Zymkey does

Zymkey adds enhanced security to remote Linux applications running in IoT devices and thin clients. It's designed to be an easy plug-in to existing designs, requiring only a small client side 'connect-service' integrated with user applications. This unique product will be available in USB and I2C formats as well as OEM licenses.

We received samples of the redesigned Zymkey rev 2 in mid April and we've been working through a number of manufacturing and design issues since then. Last week we approved the USB version to production and we're excited to share some of the details in this post.

Shipment dates

We are now working on streamlining the manufacturing, test and programming processes and completing the cloud-based security services. Our target release date for the USB version is late October 2016 with first shipments going to customers with pre-orders. The I2C version is expected to ship about six to eight weeks after USB shipments.

USB version will be released first

We are releasing the USB version first because the demand is greater for this device and it's easier for developers to get started with. The I2C version will be released about six to eight weeks later, subject to final testing. It has very similar security functionality and form factor, except for the connector which is an eight pin header.

Enclosure for USB version

The first batches of Zymkey-USB will be supplied with a plastic 'USB stick' enclosure designed to protect the components from mechanical damage. This is a two part snap together design that provides access to the battery if needed.

Security features at release

Zymkey adds enhanced security to remote Linux applications running in IoT devices and thin clients. It's designed to be an easy plug-in to existing designs, requiring only a small client side 'connect-service' to be integrated into the user application. This connect service talks to Zymbit security services which manage key binding, device authentication and encryption keys. Raspian/Debian will be supported at release, other target devices will follow. Full details of features and their use will be released with first product shipments.

Manufacturing update

This first batch of Zymkeys were manufactured on a pilot SMT line at an ISO9001 facility in Southern California. A pilot line is typically slower than main production equipment and is used to work through any issues relating to board design, machine set up, solder stencils,etc. This first run of USB keys went pretty smoothly and a transition to high volume production will be straightforward.

Bare Zymkeys ready to start their journey: gold finish, ten to a panel, taped USB fingers.
