The SHA105 is a member of the CryptoAuthentication product family. The device provides 128-bits of symmetric security 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 either one-side or mutual authentication is desired. The SHA105 operates as the host side device in systems with mutual authentication. Consider using the SHA104 for the client symmetric key on your disposable or accessory system.
