    • Description

    The SHA105 TrustFLEXAUTH is a member of the CryptoAuthentication product family. The device provides 128-bits of symmetric security and run a SHA256 checkMAC from the MAC coming from a SHA104 client. The TrustFLEX variant of the device allows this pre-configured device to be purchased at a minimum orderable quantity of 2,000 units including the secure key provisioning service from Microchip. You don't what the provisioning service ? Consider the standard SHA105.


    It is targeted for disposable and ecosystem control applications and is intended to be used as a companion device with Microchip or other vendor’s microcontrollers. The device can be used in systems where symmetric authentication is desired. The SHA105 operates as the host side device in systems where protection of the symmetric key on the host side is required. Consider using the SHA104 for the client symmetric key on your disposable or accessory system.
