The Continuous Glucose Monitor (CGM) plays a crucial role in the treatment of Diabetes by wirelessly transmitting glucose measurements as frequently as every 5 minutes to a receiver or smartphone. CGMs are shrinking to enhance patient compatibility, which limits the physical space available for computational resources making them unsuitable for traditional cryptographic schemes. The National Institute of Standards and Technology (NIST) has called for encryption algorithms to be considered for the lightweight cryptographic standard to be used in resource-constrained environments like a CGM. We provide experimental evidence of the resource consumption of a NIST lightweight finalist in comparison to the Advanced Encryption Standard (AES) when implemented onto the same chip used in CGMs.
