Blowfish is an online sex toy catalog offering erotic toys, books, supplies and videos. History Founded May 1, 1994 Blowfish was one of the first online sex toy catalogs. With the motto Good Products for Great Sex , Blowfish is known for their honest, thorough and often humorous reviews of their products. We cater to the clean, well lit market, founder Christophe Pettus once remarked, but we re also appealing to those who are old fashioned enough to think that sex should be a little bit dirty. Blowfish is also, according to the http www.sfbg.com 39 51 sex toy.html San Francisco Bay Guardian , known for carrying a number of sex toys as art forms, often fashioned out of glass. In 2003 Blowfish created Blowfish Video with their release of Clearly Sex, a video highlighting handmade acrylic sex toys created by local artist Cate Cox. In 2005 Blowfish Video teamed up with Pink and White Productions and produced The Crash Pad, the first video directed by Shine Louise Houston. The Crash Pad was well received and lauded for featuring realistic lesbian sex. Later that year, The Crash Pad went on to win the 2005 Feminist Porn Award for Hottest Dyke Sex Scene. In 2006 Blowfish Video and Pink and White Productions produced Shine s second hit, Superfreak named after the 1981 hit single, Superfreak produced and performed by Rick James, the movie features the ghost of the funk star coming back and creating sexy mischief at an all girl party , which won the 2007 Feminist Porn Award for Best Dyke Scene.

The Scream cipher is a word based stream cipher developed by Shai Halevi , Don Coppersmith and Charanjit Jutla from IBM . The cipher is designed as a software efficient stream cipher. The authors describe the goal of the cipher to be a more secure version of the SEAL cipher SEAL cipher. The general design of Scream is close to the design of SEAL with block cipher like round functions. There are two versions of Scream. One of them, Scream F , reuses the S box es from the Advanced Encryption Standard AES block cipher, while the other, Scream , internally generates new, key dependent S boxes as part of the initialization phase. The round function is also based on the AES round function, but is narrower, 64 bits instead of 128 bits. The cipher uses a 128 bit key and a 128 bit nonce. It is efficient in software, running at 4 5 cycles per byte on modern processors. The cipher was presented at the Fast Software Encryption FSE conference in 2002.

unreferenced date June 2009 In classical cryptography , a permutation cipher is a transposition cipher in which the cryptographic key key is a permutation . To apply a cipher, a random permutation of size e is generated the larger the value of e the more secure the cipher . The plaintext is then broken into segments of size e and the letters within that segment are permuted according to this key. In theory, any transposition cipher can be viewed as a permutation cipher where e is equal to the length of the plaintext this is too cumbersome a generalisation to use in actual practice, however. Identifying the cipher Because the cipher doesn t change any of the characters, the ciphertext will have exactly the same letter frequencies as the underlying plaintext. This means that the cipher can in many cases be identified as a transposition by the close similarity of its letter statistics with the letter frequencies of the underlying language. Breaking the cipher Because the cipher operates on blocks of size e , the plaintext and the ciphertext have to have a length which is some multiple of e . This causes two weaknesses in the system first, the plaintext may have to be padded if the padding is identifiable then part of the key is revealed and second, information relating to the length of the key is revealed by the length of the ciphertext. To see this, note that if the ciphertext is of length i then e must be one of the divisor s of i . With the different possible key sizes different possible permutations are tried to find the permutation which results in the highest number of frequent bigram s and trigram s as found in the underlying language of the plaintext. Trying to find this permutation is essentially the same problem encountered when analysing a Transposition cipher Columnar transposition columnar transposition cipher multiple anagram ming .

refimprove date February 2009 In cryptography , a product cipher combines two or more transformations in a manner intending that the resulting cipher is more secure than the individual components to make it resistant to cryptanalysis . ref Handbook of Applied Cryptography by Alfred J. Menezes, Paul C. van Oorschot, Scott A. Vanstone. Fifth Printing August 2001 page 251. ref The product cipher combines a sequence of simple transformations such as substitution cipher substitution , transposition cipher permutation , and modular arithmetic . The concept of product ciphers is due to Claude Shannon , who presented the idea in his foundational paper, Communication Theory of Secrecy Systems . For transformation involving reasonable number of n message symbols, both of the foregoing cipher systems the S box and P box are by themselves wanting. Shannon suggested using a combination of Substitution box S box and Permutation box P box transformation a product cipher. The combination could yield a cipher system more powerful than either one alone. This approach of alternatively applying substitution and permutation transformation has been used by IBM in the Lucifer cipher system, and has become the standard for national data encryption standards such as the Data Encryption Standard and the Advanced Encryption Standard . A product cipher that uses only substitutions and permutations is called a SP network . Feistel cipher s are an important class of product ciphers.

Or, the mystery of Admiral Beaufort s cipher . Mathematics and Computers in Simulation 35 1993 327 367 ref . Its most famous application was in a rotor based cipher machine, the M 209 Hagelin M 209 ref Mollin, Richard A., An Introduction to Cryptography , page 100. Chapman & Hall CRC, 2001 ref . Using the cipher To encrypt or decrypt for that matter , first choose the plaintext character from the top row of the tableau,call this column P. Secondly, travel down column P to the corresponding keyLetter K. Finally, move directly left from the Key letter to the left edge of the tableau, the CipherText encryption of Plaintext P with Key K will be there. For example if encrypting Plain text character d with Key m the steps would be 1 find the column with d on the top, 2 travel down that column to find Key m , 3 travel to the left edge of the tableau to find the CipherText letter J in this case . The Beaufort cipher is a reciprocal cipher , that is, Decryption and Encryption algorithms are the same. Distinguished from variant Beaufort The Beaufort cipher should not be confused with the variant Beaufort cipher.

In order to keep the algorithm secret, it is only distributed as a microchip named Pluto and not as a piece of software. It is possible to have a secret cipher algorithm while still reaping the benefits of public cryptography research one way is to make a non weakening change to a public algorithm, like changing the Nothing up my sleeve number s, or chaining the public cipher with an unrelated secret cipher.
