Cryptanalysis of WG-7: a lightweight stream cipher
Cryptanalysis of WG-7: a lightweight stream cipher is a scholarly work by Josef Pieprzyk, Ron Steinfeld, and Mohammad Ali Orumiehchiha, published in 2012 in ''Cryptography and Communications''. The main subjects of the publication include running key cipher, arithmetic, lock, computer science, block cipher mode of operation, stream cipher attack, cryptanalysis, stream cipher, affine cipher, keystream, cryptography, two-square cipher, theoretical computer science, cipher, Transposition cipher, differential cryptanalysis, and Correlation attack. The authors show that the key stream generated by WG-7 can be distinguished from a random sequence after knowing 213.5 keystream bits and with a negligible error probability.
