Classification of Attacks

Q: Assume that an IoT device has a security scheme that uses an $m$ password key digit, i$.$e$.,k=(k_{m-1},k_{m-2},$dots,$k_0{)}_2.$ The processor inside the runs the following algorithm:

IOT Encryption Algorithm:

Input: the binary digit key $k=(k_{m-1},k_{m-2},$dots,$k_1,k_0{)}_2,k_{i}in\{0,1\}.$

For $i=m-1$ down to $0$ do

run a Square operation $()$

if $k_i=1$ run a Multiply operation $0$

End For

vdots

Explain how the side channel attack can be used in this IoT device to ob the value of the binary digit key $k.$
