http://superm.math.hawaii.edu/_pdfs/lessons/k_five/cryptologyFrequency_analysis/frequency%20analysis%20overview.pdf WebFrequency analysis is a cryptanalysis technique that focuses on counting letters or groups of letters in the encrypted text to aid in breaking it. Frequency analysis assumes that in sufficiently large texts of one language, the average frequency of occurrence of a certain letter is the same.

WebApr 16, 2024 · We answer this question in the affirmative, and show that we can allow arbitrarily large gaps between m and n, up to exponential \(m = 2^{O(n)}\).Surprisingly, this shows that unlike time-bounded public-key cryptography,—where we must rely on additional computational assumptions,—space-bounded public-key cryptography can be proven …
