function examples for some of the most common application cases Meeting the Needs of Developers With STM32 Open Development Environment 10 11 12 IoT is a movement where any system is able to leverage the Internet and its eco-system Cloud computing – Low cost embedded computers – Explosion of reliable wireless connectivity – Rapid innovation of low cost sensors Nodes Gateways Cloud Smart Things (With intelligence) Simple Things (Send raw data) Gateway Network infrastructure (Switch / Router) Servers (Big data & cloud) Sense – Process – Connect – Power - Secure Process – Connect – Power - Secure Process – Power - Secure Security is a key enabler for IoT 13 Attacks examples Oct 21st - DDoS attack on Dyn came from 100,000 infected devices 14 Data security, 37% of respondents Privacy concerns, 33% of respondents Data quality, 34% of respondents Use of legacy systems, 34% of respondents Insufficient skills of technology staff, 35% of respondents Reported by Genpack Research Institute Risks on Data privacy Data authenticity Counterfeiting OTHER OTHER According to a panel of senior executives from worldwide manufacturing companies Threats Needs User data corruption & eavesdropping Data privacy & confidentiality Secure Data storage Secure Data communication Encryption & signature Device counterfeiting Resistance against cloning, hacking Device authentication Device to device Device to server Device malfunction Service & network access corruption Prevent denial of service Platform Integrity Secure boot Secure firmware upgrade Answer 15 16 Authentication Authentication of one entity by the other • Prover holds a secret • Prover releases to the verifier a proof without exposing secret, using a cryptographic algorithm • Asymmetric cryptography challenge response Authentication Process Certificate Secure data communication Data is encrypted and transferred from one entity to the other • Both entities hold the same secret (key) • Symmetric cryptography Security mechanism rely on secrets Secrets are keys 17 Level of Security depends on how secrets are generated, stored, and handled 18 Strong trusted components • Highly secure solution Hardware &
