My amateur understanding, osmosed from everything I've avidly read, is that Alan Turing independently discovered and applied Bayes theorem to the cracking of the M4 Enigma. Bayes theorem could be described as 'inference'. Turing didn't have a direct hand in attacking Fish nor the building of Colossus but his probabilistic approach was adopted by the ...

all the cryptography methods except one time pads from the BC (before computer) era were effectively made obsolete by computers. The amazing WW2 work against enigma were a bridge between the old and the new eras.

In 2006-07, NIST published a new standard for cryptographically secure random number generation. One of their suggestions was based on elliptic curves, DUAL_EC_DRBG. in 2006, Daniel Brown and Kristian Gjosteen discovered that this algorithm had a subtle bias for certain numbers. Later, in 2007, Dan Shumow and Niels Ferguson said they had found what caused ...

WEP for securing wireless networks: Wired Equivalent Privacy (WEP) is a security algorithm for IEEE 802.11 wireless networks. Introduced as part of the original 802.11 standard ratified in 1997, its intention was to provide data confidentiality comparable to that of a traditional wired network. WEP, recognizable by the key of 10 or 26 hexadecimal digits, ...

DES has not been mentioned in the previous two answers. Although it was known to be quite weak from very early on it was widely used for a couple of decades at least, until newer algorithms (3DES, AES, but also e.g. RC4) displaced it. Nowadays it can be broken in hours with dedicated hardware or with at most a few thousand dollars of cloud computing time. ...

This is a shot in the dark, but could you be thinking of the Needham-Schroeder protocol? It was published in 1978 [1], and an attack was published as much as 18 years later, in 1996 [2]. It is not an encryption method, though, but a protocol. In fact, the original paper does not even specify an encryption method to be used, but uses encryption symbolically. ...

You could be thinking about the Merkle-Hellman knapsack cryptosystem. It was invented in 1978 and everything seemed well and good until it was completely broken six years later in 1984 by Shamir - it was a complete and total break, i.e. the cryptosystem became unusable overnight. That said I don't know if the knapsack cryptosystem was ever "popular" in the ...
