The amount of Implantable Medical Devices (IMD)

keeps booming in recent years. However, not many

of them have encryption and decryption methods to

protect their data communication. The purpose of

this thesis work is to profile various popular

symmetric encryption algorithms and select the best

candidates as the benchmark for generic IMD.

Moreover, this thesis gives suggestions for design

digital CPU for generic IMD based on lab work

simulation output.

This thesis work will focus on profiling and analyzing

several metrics: average power consumption, peak

power consumption and energy consumption of all

candidates because those metrics are the crucial

constraint of IMD. Also the background information

of all candidates will be introduced and all relevant

metrics such as security level, encryption rates of all

candidates will be discussed in this thesis work.
