WebCryptanalysis This section documents the ways in which many cryptographic ciphers can be cryptanalysed and broken. The easiest ciphers to break are the ones which have existed for a long time. With this in mind, we will be focussing on classical ciphers, as these will be the easiest to explain.

Webon Grain version 1 (written as Grain-1, for rest of our paper), includes: a correlation attack based on linear approximation [3] and a distinguishing attack using linear circuit approximation WebCryptanalysis. Several attacks and attempts at cryptanalysis of E0 and the Bluetooth protocol have been made, and a number of vulnerabilities have been found. In 1999, Miia Hermelin and Kaisa Nyberg showed that E0 could be broken in 2 64 operations (instead of 2 128), if 2 64 bits of output are known.
