§ Security is required for all deployments§ IoT will not be successful unless it can be trusted§ When you add networking everything changes§ Unprotected IoT presents a huge attack surface

§ mbed TLS: End to End Communications Security§ Built on open internet standards§ Proven PolarSSL technology from Offspark

§ mbed OS Cryptobox: Device Security§ Removes application and stack from attack surface§ uvisor enabling trusted secure partitioning§ Efficient cryptographic services§ Firmware over the air updates maintain security
