Sending Encrypted Data via GPRS & SMS

by Piret Uustal

Wow, time is moving quickly, and we have only about two weeks left to reach our funding goal! We are getting close to the end of the SKUDO Kryptor campaign, but you still have time to take advantage of our unique crowdfunding offer and receive a completely free HSM softcore with each purchase of a SKUDO Kryptor FPGA board. This offer is available only to those who back our campaign by September 28th. We hope you will have fun experimenting with and making use of the encryption functionality offered by this chip to create your very own encrypted communication solutions.

Using SKUDO Kryptor, SMS, and GPRS for Encrypted Communication

This week we are highlighting another very interesting project as an example of what you can build using SKUDO Kryptor. In this tutorial we combine SKUDO Kryptor with a basic, affordable 2G data modem to send encrypted data (using a BME280 sensor as a source) via SMS and a GPRS data link. This project is an example of how you can encrypt and send any type of IoT sensor data by using an affordable yet competitive mobile network. So have a look and try it out yourself once you receive your SKUDO Kryptor board!

Technical Questions

For anyone who’s interested in more technical details, you are welcome to contact us using the Ask a technical question link below. We had a small glitch, during the first few weeks of the campaign, that delayed our responses to some of your questions, but we are now available and will get back to you very quickly. So please do not hesitate to contact us any time with your questions, comments, and requests. We are always very excited to hear from you!

Open Source Details & Our Vision for SKUDO Kryptor

During the campaign we received a few questions regarding whether or not our Verilog source code is open source, so we’d like to clarify that a bit. The algorithms we are using (Camellia, Skein, etc) are open source, as is our hardware (we will publish our PCB design and schematics after the successful end of the campaign and before we begin shipping to backers). For the time being, however, our Verilog implementation is not open source. Our company is still in the start-up phase, and we have invested considerably, over the past few years, in the development of these implementations. As such, we are not yet in a position where we can afford to open source them.

Our vision for this crowdfunding campaign has been to adopt strong, professional encryption technology used in specific niche markets, such as space applications, and make it accessible to and affordable for a wider audience that includes makers and IoT enthusiasts. That goal has been the driving force behind the SKUDO Kryptor project, and we are excited that we will be able to provide this solution to our backers.

We hope this gives you clearer insight into aims and objectives. We look forward to having you among our backers during these last weeks of our campaign. Let’s make it happen together!
