Table 6 Software implementation performance metrics

From: Trade-off of security and performance of lightweight block ciphers in Industrial Wireless Sensor Networks

Metric Definition
Code size (bytes) Memory size to store the cipher code and constants.
  Typically, resides in flash memory.
RAM size (bytes) Memory size to store the intermediate states during
  the execution of the cipher code.
Cycles/byte Number of cycles to encrypt (decrypt or both) one block.
Throughput Number of encrypted bits per second (Kbps).
Combined metric Code size ×Cycle_count/Block _size.
