Block is the data exchange … WebJan 3, 2024 · A cache timing side channel involves an agent detecting whether a piece of data is present in a specific level of the processor’s caches, where its presence may be used to infer some other piece of information. One method to detect whether the data in question is present is to use timers to measure the latency to access memory at the address.

Because side-channel attacks rely on the relationship between information emitted (leaked) through a side channel and the secret data, countermeasures fall into two main categories: (1) eliminate or reduce the release of such information and (2) eliminate the relationship between the leaked information and the secret data, that is, make the leaked information unrelated, or rather uncorrelated, to the secret data, typically through some form of randomization of the ciphertext t… WebCache Timing Analysis of LFSR-Based Stream Ciphers.
