The initial solution relies on a low-cost, low-power secure 32-bit microcontroller supplied by StarChip, with a dual certification from EMVCo (Europay Mastercard Visa) and Common Criteria Evaluation Assurance Level, delivered in a 3 x 3 DFN6 package and other standard packages making it an easy-to-integrate companion chip in any sensor, device, or gateway.
The StarChip secure microcontroller is programmed at Avnet Memec-Silica’s secure warehouse with a firmware supplied by Trusted Objects, adding a set of functions and commands tailored for the exact requirements of the customer’s final application and global security architecture. The programmed secure microcontroller thus becomes a secure element with the capability to perform cryptography primitives and complex functions comprising and not limited to AES, ECC encryption, decryption, signature, secure key renewal (Diffie-Hellman), on-board key generation, true random number generation, handling of certificates, and more while never exposing secret keys to the outside world.
This secure element is personalised with the support of Trusted Objects at Avnet Memec-Silica’s secure warehouse with unique public keys, private keys, certificates and identifiers generated on-site by a dedicated HSM (Hardware Security Module) as per the security scheme required by each customer’s application and global security architecture. Secure elements and, if needed, matching whitelists, are then securely made available to the customer or its manufacturing partner.
Example codes implementing various secure protocols, both at the embedded and server levels, will be provided and demonstrated with Avnet Memec-Silica’s Visible Things IoT platform.
Philippe Fremont, vice-president of Technical Marketing EMEA with Avnet Memec-Silica comments: “Whereas connecting objects, devices and machines to enterprise IS/IT enables a breadth of new services in the consumer and industrial IoT, we believe it should not jeopardise the global security of such systems... [introducing] this highly flexible innovative certified security platform able to handle end-to-end security inside and above communication networks for every one of our customers.”
