W74M Authentication FlashThe simplest and quickest way to add “multi-layer authentication” into your existing designs
General DescriptionWinbond W74M product family comes with standard HMAC-SHA-256 crypto accelerator and 4 separate Monotonic Flash Counters that are HMAC-signed by individual secret keys. System utilizing each Monotonic Flash Counter can not only verify the integrity and authenticity of the counter values, but also add a timestamp to the message/information transmitted with the resistance to reply attacks. W74M enables system designers to strengthen code/data storage as well as delivers increased security for the emerging IoT demanding multi-layered authenticity.
