Systems and methods for providing a battery modulewith secure identity information and authentication of the identity of the batteryby a host. In one embodiment, the system for providing a battery module with secure identity information includes: (1) a tamper resistant processing environmentlocated within the battery moduleand (2) a key generator configured to generate a key based on an identity of the battery moduleand cause the key to be stored within the tamper resistant processing environment

Host/battery with public/private busses, public memory, processor, and private memory

Authentication with battery and host programmed with shared identity key

Public/private non-volatile memory battery with root key index, identity key

Decrypting identity key from battery with root key in host

System and method for secure authentication of a 'smart' battery by a host

Battery processor circuitry with separate public and private bus
