So Which Is the Best Lightweight Encryption/Hashing Method? It’s TinyJambu
I have been reviewing a number of research papers, and doing some online research, and have created a scorecard for the performance, area and energy efficiency of the 10 LWC (Lightweight Cryptography) methods:
You can read about the analysis here:
In the following, I have rated the encryption performance, chip area and energy efficiency from 10 (base) to 1 (worst), and the hash method from 4 (best) to 1 (worst):
We can see that we have the excellent methods of TinyJAMBU, Xoodyak and ASCON, and which are generally good in every area. Next comes SPARKLE, (let down on energy and area), GIFT-COFB, Romulus and Grain-128. Finally, we have the weak methods of PHOTON-Beetle, ISAP and Elephant, and which are generally weaker in most respects.
The best all-rounders are then Xoodyak and ASCON, and the overall winner is TinyJambu. It looks like TinyJambu has found a sweet spot in the balance between security (120 bits) and energy consumption. Overall, it is clocked at 32 bits, whereas most of the other methods are clocked at a large value than this.
Here is an outline of many of the methods:
