To improve battery identification, an electrical identification scheme could be used so that simple physical counterfeiting is no longer enough to replicate the battery. Figure 1 shows the ID authentication functional block diagram. The challenger or host sends a command to read the data from the device (responder).
The selection of the battery authentication scheme between the simple ID authentication and SHA-1/HMAC-based authentication depends on the security level needed and cost for the applications. The simple ID authentication is the least expensive and is good for cost-sensitive applications, but it is easy to replicate.
To authenticate a battery pack, the host generates a 160-bit random challenge. The generated random challenge is transmitted to the authentication device, which uses the secret key along with the 160-bit random challenge from the host to calculate the authentication digest value.
When the host and the authentication device have completed the calculation, the host reads the authentication digest value from the authentication device. It then compares it to its own value. If the values match, the battery pack is authenticated.
Then, if the polarity of this virtual battery is opposed to the 6V battery and its voltage is larger than 6V, you will get a current flow against the normal battery current flow given by the difference of battery voltages divided by the Thevenin resistance.
So the sum of the contributions to the current of each of the three batteries is equal to the actual current in the circuit. The reason for doing this is to show that unless the circuit is relatively simple it is very difficult to predict which way the a current will flow throough a battery. Yeah i know.
