Jazz

Jazz is a music genre that originated from African American communities of New Orleans in the United States during the late 19th and early 20th centuries. It emerged in the form of independent traditional and popular musical styles, all linked by the common bonds of African American and European American musical parentage with a performance orientation. Jazz spans a period of over a hundred years, encompassing a very wide range of music, making it difficult to define. Jazz makes heavy use of improvisation, polyrhythms, syncopation and the swing note, as well as aspects of European harmony, American popular music, the brass band tradition, and African musical elements such as blue notes and African-American styles such as ragtime. Although the foundation of jazz is deeply rooted within the black experience of the United States, different cultures have contributed their own experience to the music as well. Intellectuals around the world have hailed jazz as "one of America's original art forms".

Jazz (Kanso series)

Jazz (Kanso series) is a series of 20 paintings made by Nabil Kanso in 1978-79. The subjects of the works are based on the jazz music and the entertainments night life in New York and New Orleans. The paintings are done in oil and acrylic on canvas measuring 224 X 182 cm (88 X 72 inches) each. Their compositions reflect predominant red tonality built with broad brushstrokes. Works from the series were exhibited in Atlanta in 1985.

Crypto++

Crypto++ (also known as CryptoPP, libcrypto++, and libcryptopp) is a free and open source C++ class library of cryptographic algorithms and schemes written by Wei Dai. Crypto++ has been widely used in academia, student projects, open source and non-commercial projects, as well as businesses. Released in 1995, the library fully supports 32-bit and 64-bit architectures for many major operating systems and platforms, including Android (using STLport), Apple (Mac OS X and iOS), BSD, Cygwin, IBM AIX and S/390, Linux, MinGW, Solaris, Windows, Windows Phone and Windows RT. The project also supports compilation under C++03 and C++11, a variety of compilers and IDEs, including Borland Turbo C++, Borland C++ Builder, Clang, CodeWarrior Pro, GCC (including Apple's GCC), Intel C++ Compiler (ICC), Microsoft Visual C/C++, and Sun Studio.

Algorithms

Crypto++ ordinarily provides complete cryptographic implementations, and often includes less popular, less frequently-used schemes. For example, Camellia is an ISO/NESSIE/IETF-approved block cipher roughly equivalent to AES, and Whirlpool is an ISO/NESSIE/IETF-approved hash function roughly equivalent to SHA; both are included in the library.

Crypto-1

Crypto1 is a proprietary encryption algorithm created by NXP Semiconductors specifically for Mifare RFID tags, including Oyster card, CharlieCard and OV-chipkaart.

Recent cryptographic research has shown that, "the security of this cipher is ... close to zero". Crypto1 is a stream cipher very similar in its structure to its successor, Hitag2. Crypto1 consists of

It can operate as an NLFSR and as an LFSR, depending on its input parameters. Outputs of one or both linear and nonlinear functions can be fed back into the cipher state or used as its output filters. The usual operation of Crypto1 and Hitag2 ciphers uses nonlinear feedback only during the initialization/authentication stage, switching to operation as LFSR with a nonlinear output filter for encrypting the tag's communications in both directions.
