wolfSSL / wolfCrypt demonstration package for Atmel ATECC508A

Package Contents

This package contains the following:

  1. Atmel Studio client / server TLS examples using PK_CALLBACKS. See tls_demo/README.md
  2. Atmel ASF Framework wolfCrypt example using GCC ARM Makefile. See wolfcrypt_test/README.md
  3. Atmel ASF Framework wolfSSL Client example using GCC ARM Makefile. See wolfssl_client/README.md

Benchmarks

Software only implementation (SAMD21 48Mhz Cortex-M0, Fast Math TFM-ASM):

ECC  256 key generation  3123.000 milliseconds, avg over 5 iterations
EC-DHE   key agreement   3117.000 milliseconds, avg over 5 iterations
EC-DSA   sign   time     1997.000 milliseconds, avg over 5 iterations
EC-DSA   verify time     5057.000 milliseconds, avg over 5 iterations

ATECC508A HW accelerated implementation:

ECC  256 key generation  144.400 milliseconds, avg over 5 iterations
EC-DHE   key agreement   134.200 milliseconds, avg over 5 iterations
EC-DSA   sign   time     293.400 milliseconds, avg over 5 iterations
EC-DSA   verify time     208.400 milliseconds, avg over 5 iterations

For reference the benchmarks for RNG, AES, MD5, SHA and SHA256 are:

RNG      25 kB took 0.784 seconds,    0.031 MB/s (coming from the ATECC508A)
AES      25 kB took 0.177 seconds,    0.138 MB/s
MD5      25 kB took 0.050 seconds,    0.488 MB/s
SHA      25 kB took 0.141 seconds,    0.173 MB/s
SHA-256  25 kB took 0.352 seconds,    0.069 MB/s
