In today’s connected world, there’s no denying smart devices need reliable security. If you’re looking for a cost-effective memory with authentication, you’ll find everything you need in Winbond’s W74M memory devices. These non-volatile memory products, equipped with multi-layered authentication, add a robust layer of security to IoT devices.

The multi-layer authentication is accompanied by a “Challenge and Response” routine which involves the private root key and updated Monotonic Flash Counter value. Each W74M can provide authentication service for up to 4 different hosts or systems to ensure that a product, consumables it uses, firmware it runs, accessories that support it, and the network nodes it connects to are not cloned or counterfeited.

This webinar will address:

  • Differences between Symmetric and Asymmetric Crypto
  • Monotonic Flash Counter and its purpose
  • Authentication & Multi-layered Authentication
  • HMAC-SHA-256
  • Challenge and Response
