  2. Advanced Encryption Standard process - Wikipedia

    en.wikipedia.org/wiki/Advanced_Encryption...

    Advanced Encryption Standard process. The Advanced Encryption Standard (AES), the symmetric block cipher ratified as a standard by National Institute of Standards and Technology of the United States (NIST), was chosen using a process lasting from 1997 to 2000 that was markedly more open and transparent than its predecessor, the Data Encryption ...

  3. Rijndael S-box - Wikipedia

    en.wikipedia.org/wiki/Rijndael_S-box

    Design criteria. The Rijndael S-box was specifically designed to be resistant to linear and differential cryptanalysis. This was done by minimizing the correlation between linear transformations of input/output bits, and at the same time minimizing the difference propagation probability. The Rijndael S-box can be replaced in the Rijndael cipher ...

    en.wikipedia.org/wiki/AES_implementations

    AES-256 A byte-oriented portable AES-256 implementation in C. Solaris Cryptographic Framework offers multiple implementations, with kernel providers for hardware acceleration on x86 (using the Intel AES instruction set) and on SPARC (using the SPARC AES instruction set). It is available in Solaris and derivatives, as of Solaris 10.

  5. NSA Suite B Cryptography - Wikipedia

    en.wikipedia.org/wiki/NSA_Suite_B_Cryptography

    NSA Suite B Cryptography. NSA Suite B Cryptography was a set of cryptographic algorithms promulgated by the National Security Agency as part of its Cryptographic Modernization Program. It was to serve as an interoperable cryptographic base for both unclassified information and most classified information . Suite B was announced on 16 February 2005.

  6. ARIA (cipher) - Wikipedia

    en.wikipedia.org/wiki/ARIA_(cipher)

    In cryptography, ARIA is a block cipher [1] designed in 2003 by a large group of South Korean researchers. [2] In 2004, the Korean Agency for Technology and Standards selected it as a standard cryptographic technique. The algorithm uses a substitution–permutation network structure based on AES. The interface is the same as AES: 128-bit block ...

  7. Advanced electronic signature - Wikipedia

    en.wikipedia.org/wiki/Advanced_electronic_signature

    The advanced electronic signature is one of the standards outlined in eIDAS. For an electronic signature to be considered as advanced, it must meet several requirements: [3] [4] The signatory can be uniquely identified and linked to the signature. The signatory must have sole control of the signature creation data (typically a private key) that ...

  8. UES (cipher) - Wikipedia

    en.wikipedia.org/wiki/UES_(cipher)

    UES. In cryptography, UES ( Universal Encryption Standard) is a block cipher designed in 1999 by Helena Handschuh and Serge Vaudenay. They proposed it as a transitional step, to prepare for the completion of the AES process . UES was designed with the same interface as AES: a block size of 128 bits and key size of 128, 192, or 256 bits.

  9. Block size (cryptography) - Wikipedia

    en.wikipedia.org/wiki/Block_size_(cryptography)

    Block size (cryptography) In modern cryptography, symmetric key ciphers are generally divided into stream ciphers and block ciphers. Block ciphers operate on a fixed length string of bits. The length of this bit string is the block size. Both the input ( plaintext) and output ( ciphertext) are the same length; the output cannot be shorter than ...
