Encrypted Voice on Raspberry Pi: Key Load and Rotation, Device Deployment, and More!

This video demonstrates the new features which have been added to the Crypto Voice Module software for Encrypted Voice over Radio using a Raspberry Pi. Software available here: https://github.com/aarmono/crypto_tra... How to build your own using commodity hardware: https://github.com/aarmono/crypto_tra... These features include: Volume buttons Multiple Keys with Key Rotation using button presses or the Console Interface Key Load from either an SD Card or USB Drive using button presses or the Console Interface Text To Speech Alert Broadcasts using button presses or the Console Interface Plan/Secure selection using a dedicated button or the Console Interface A Device Deployment workflow for producing write-protected SD Cards for devices with or without a screen which prevent configuration changes or Console Interface access. A Key Deployment workflow for producing SD Cards or USB Drives with just keys loaded I provide some recommendations on when particular Device and Key Deployment options should be used. The use of USB Drives for key storage also opens up some options for using commercial off the shelf encrypted USB Drives for key storage and more advanced key management. I've never used any, and some have terrible security (if you go this route I recommend you type the model name of the drive you're considering and the word "hacked" in a search engine to see if someone has broken it); but any which use the standard USB Mass Storage Device interface and don't require custom device drivers should work. Such products may claim to work with printers, scanners, or embedded devices. Still, I recommend that keys not be stored on SD cards or USB drives for longer than is necessary to load them onto devices. After recording this video I came across some extremely low cost micro SD cards which didn't implement any of the "write protect" features required by the SD card spec. If that's a feature you plan to depend on, you may want to contact the vendor to find out if the cards you plan to buy support it. There are also "write once, read many" (WORM) micro SD cards designed for law enforcement applications which provide hardware-level guarantees that data written to them cannot be modified. These features would never have happened were it not for people talking to me through either youtube comments or github discussions, so I appreciate those interactions. 0:00 Demo 1:44 Intro 2:50 Configure Push To Talk 3:19 Default GPIO Pin Configuration 3:38 Console Controlled PTT 4:00 Set Configuration Password 4:53 Configure Text to Speech Alerts 5:51 Configure Radio Mode 6:09 Saving Configuration to SD Card 6:23 Encryption Key Storage Commentary 10:30 Base Station Configuration Overview 11:31 Generating Encryption Keys 11:42 Locked Device Deployment Overview 11:59 Deploy Locked Device With Keys 12:37 Deploy Locked Device Without Keys + USB Stick with keys 13:30 Demo of "Display Locked" feature 13:45 Handheld Configuration Overview 15:48 Action Button Key Select Procedure 16:39 Action Button Key Load Procedure 17:43 Key Zeroize 18:05 Outro
