Secure Element Firmware

Our products are based on Trusted Objects Secure Software Platform designed to comply with the requirements of constrained applications like IoT: strong security, low power consumption, easy connectivity, seamless integration and more.



Trusted Objects Secure Firmware (TOSF) is a configurable secure firmware solution for Secure Element (SE)-based hardware implementation.

 

The Secure Element embedding TOSF is a tamper-resistant companion chip in an IoT device platform that handles the security functions and security protocols, including:

  • Authentication,

  • Data transfer integrity and data transfer confidentiality,

  • Secure boot and secure firmware update,

  • Secure storage,

  • Intellectual Property protection,

  • Secure LoRaWAN, TLS/DTLS implementation. 

 

TOSF security functions and secure protocols are based on powerful cryptography algorithms fully suited for the IoT applications security: ECC (Elliptic Curve Cryptography) 256-bit key length, AES 128-bit & 256-bit, SHA256 …

 

TOSF is hardware-agnostic and can be ported on any secure element; it is currently qualified on two secure micro-controller hardware:

  • AVNET TO136 Secure Element based on IDEMIA-StarChip platform,

  • TESIC SE IP from Tiempo Secure.

 

All our secure products have a common API, so developers can easily switch from one implementation to another.

 

Trusted Objects can also tailor its firmware to specific needs, or develop specific firmware depending on customer requirements.
