This paper is the origin of what has become known as Moore’s Law, which states that the number of transistors on integrated circuits doubles approximately every two years. Moore’s Law is directly related to other aspects of progress in computing, including processing speed, product price, and memory capacity.

Cryptographic algorithms are all vulnerable to brute force–trying every possible encryption key, systematically searching for hash-function collisions, factoring the large composite number, and so forth–and brute force gets easier with time (due to Moore’s Law).”

Moore’s Law is directly related to cryptography or, more specifically, to cryptanalysis.
