Plug and play “HSM on a chip” encyption board for makers


S500 with on the ground (with Kryptor FPGA on board)
Flying S500 with Kryptor FPGA on board
Ground Control Station with Kryptor FPGA on board
Kryptor FPGA board connected to a Raspberry Pi via SPI link


  • Model: MAX10 8K LE
  • 1376 Kbits of internal Flash
  • 378 Kb of total internal RAM
  • up to 250 GPIO
  • Runs at 10 MHz
  • Symmetric encryption speed up to 1 Mbps
  • SPI link speed up to 2 Mbps
  • UART speed up to 1 Mbps
  • API / Command interface not encrypted
  • Anti piracy duplication protection (via chip ID)
  • Size 23 x 35 mm
  • Weight 4 g

How does it work?

Any controller board ( e.g. RaspberryPi, Arduino etc.) can connect to Kryptor via SPI, I2C and UART using a simple data protocol (API software libraries are also provided) enabling access to all the functionalities of the Hardware Security Module (symmetric encryption, asymmetric encryption, hashing, keys generation/storing/management and a True Random Number Generator).


  • Key agreement scheme: Elliptic Curve Diffie-Hellman Curve25519 (ECDH)
  • Symmetric Key Block Cipher: Camellia Asymmetric: ECC25519
  • Cryptographic Hash Function: Skein
  • All functions are embedded and running in our custom FPGA chip inside Skudo products (without OS, bare-metal)
  • True Random Number Generator (TRNG) running in dedicated Hardware (FPGA)
  • The FPGA is expandable with external software functions executed inside the chip
