Key length and performance of the previous methods.

Mechanism	Key length (bits)	RAM (bytes)	ROM (bytes)	Comp. time (ms)	Evaluation; environment	Reference
KATAN32-based protocol	80	N/A	N/A	36.6	Arduino Uno + RFM22	[12]
PRESENT-based protocol	80	27	846	303.3	SP37	[6]
SPECK-based protocol	128	20	865	29.1	SP37	[6]
PRESENT-based; Enc-then-MAC	80 or 128 (unspecified)	502	7,013	19.4	RL78	[16]

In this study, KATAN32-based implementation requires 1231uJ w.r.t power [12].
