“…Although KDFs have been proven to be secure by using the mathematical analysis [7], KDFs could be susceptible to physical attacks during implementation. These types of attacks are known as side‐channel attacks [9, 10]. Side‐channel attacks exploit information leakage during cryptographic implementations such as execution time [11–13], electromagnetic radiation [14, 15], acoustic [16, 17], and power consumption [18, 19] to infer sensitive information.…”
