OWLfCrypto Features

  • Reliability guaranteed with National Intelligence Service-verified cryptographic module

  • Provided in the form of a simple library (bin)

  • Applicable without hardware design changes

  • Compatible with various mcu

OWLfCrypto Special Features

  • High security
    • Passed noise source integrity test
    • Use of random number generator (Hash_DRBG) for verification
    • More than 100,000 iterations when using key derivation (PBKDF)
  • Self test
    • A self-test is run before the cryptographic module is executed, and if the self-test fails due to a problem, the service being verified cannot be used.
  • Verifying the integrity of the cryptographic module
    • Verifying the signature value of the module to check for tampering or forgery of the cryptographic module within the cryptographic boundary.
    • Uses HMAC (SHA-256) algorithm
