Analysis of four protocols based on tropical circulant matrices
摘要
Several key exchange protocols based on tropical circulant matrices were proposed in the last two years. In this paper, we show that protocols offered by Durcheva (Eur J Inf Technol Comput Sci 2(4):11–17, 2022, https://doi.org/10.24018/compute.2022.2.4.70), by Amutha and Perumal (AIMS Math 8(7):17307–17334, 2023, https://doi.org/10.3934/math.2023885), and by Huang et al. (Appl Sci 12(15):7401, 2022, https://doi.org/10.3390/app12157401) are insecure.
