WebWG and LEX are two stream ciphers submitted to eStream – the ECRYPT stream cipher project. In this paper, we point out security flaws in the resynchronization of these two ciphers. The resynchronization of WG is vulnerable to a differential attack. For WG with 80-bit key and 80-bit IV, 48 bits of the secret key can be recovered with about 231.3 chosen … WebNov 1, 2024 · 2.1 Description of Grain v1 The keysize of Grain v1 is 80 bits and the cipher supports an IV of 64 bits. The lengths of the two registers are both 80. Thus Grain v1 can generate in total different keystream sequences.

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. chipmunk st helens

"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. " - Cryptanalysis of grain

On Grain-Like Small State Stream Ciphers Against Fast Correlation ...

WebIn 1985 Siegenthaler introduced the concept of correlation attacks on LFSR based stream ciphers. A few years later Meier and Staffelbach demonstrated a special technique, usually referred to as fast correlation attacks, that is very effective if the feedback polynomial has a special form, namely, if its weight is very low. Due to this seminal result, it is a well … WebGrain [11] is a lightweight stream cipher proposed by M. Hell, T. Johansson, and W. Meier to the eSTREAM call for stream cipher proposals of the European project ECRYPT [5]. Its 160-bit internal state is divided into a LFSR and an NFSR of length 80 bits each.
