So, Edward Snowden has some time on his hands in Russia, and decided to develop a super crypto-protected daughterboard for the Beaglebone Black. OK, the first part’s not true: Edward Snowden doesn’t have time on his hands since he’s very busy looking for an apartment in Moscow.
However, Josh Datko, Sparkfun’s hacker-in-residence and a well-known and respected player in the Beaglebone Black universe, did have time and has actually made what is being called the CryptoCape, a daughterboard which adds a hardware security layer to your BBB.
What does it do beside run robots that write in disappearing ink? Well, for around USD $60.00 it includes many useful and appealing things in these days of 24/7 snoopery:
- A trusted platform module (TPM) for RSA encryption/decryption and signing in the hardware
- AES-128 encrypted EEPROM
- ATSHA204 authentication chip that performs SHA-256 and HMAC-25
- ATECC108 that performs the Elliptic Curve Digital Signature Algorithm (ECDSA)
Don’t look NSA. Are you looking?
