Compact Dilithium Implementations on Cortex-M3 and Cortex-M4

Denisa O. C. Greconici, Matthias J. Kannwischer, Daan Sprenkels
2020 Transactions on Cryptographic Hardware and Embedded Systems  
We present three different strategies for the signing procedure which allow trading more stack and flash memory for faster speed or viceversa.  ...  Due to the iterative nature of the Dilithium signing algorithm, there is no optimal way to achieve the best speed and lowest stack consumption at the same time.  ...  We thank Peter Pessl for pointing out various improvements to our stack optimizations.  ...

Quantum-resistant digital signatures schemes for low-power IoT [article]

Hannes Hattenbach
2021 arXiv   pre-print
In this paper i am comparing some signature schemes currently in the process of standardization by the NIST.  ...  We will come to further focus on the most promising schemes FALCON and Dilithium, which differ in one signifiant aspect that makes FALCON worse for signing but very good for verification purposes.  ...  [7] , [9] These new schemes are not only resistant to quantum attacks but also improve efficiency compared to traditional cryptography by having speed improvement by a factor of 10-100.  ...
