  2. Data Authentication Algorithm - Wikipedia

    en.wikipedia.org/wiki/Data_Authentication_Algorithm

    The Data Authentication Algorithm (DAA) is a former U.S. government standard for producing cryptographic message authentication codes. DAA is defined in FIPS PUB 113, [1] which was withdrawn on September 1, 2008. [citation needed] The algorithm is not considered secure by today's standards.

  3. Digital antenna array - Wikipedia

    en.wikipedia.org/wiki/Digital_antenna_array

    Digital antenna array (DAA) is a smart antenna with multi channels digital beamforming, usually by using fast Fourier transform (FFT). The development and practical realization of digital antenna arrays theory started in 1962 under the guidance of Vladimir Varyukhin ( USSR ).

  4. One-key MAC - Wikipedia

    en.wikipedia.org/wiki/One-key_MAC

    If msb(k 0) = 0, then k 1 = k 0 ≪ 1, else k 1 = (k 0 ≪ 1) ⊕ C; where C is a certain constant that depends only on b. (Specifically, C is the non-leading coefficients of the lexicographically first irreducible degree-b binary polynomial with the minimal number of ones: 0x1B for 64-bit, 0x87 for 128-bit, and 0x425 for 256-bit blocks.)

  5. Direct Anonymous Attestation - Wikipedia

    en.wikipedia.org/wiki/Direct_Anonymous_Attestation

    Direct Anonymous Attestation (DAA) is a cryptographic primitive which enables remote authentication of a trusted computer whilst preserving privacy of the platform's user. . The protocol has been adopted by the Trusted Computing Group (TCG) in the latest version of its Trusted Platform Module (TPM) specification [1] to address privacy concerns (see also Loss of Internet anonymi

  6. One-way compression function - Wikipedia

    en.wikipedia.org/wiki/One-way_compression_function

    The algorithm returns 1, if two responses result in a collision involving the hash function that is built from a compression function applying this block cipher (0 else). The probability that the algorithm returns 1 is dependent on the number of queries which determine the security level.

  7. PBKDF2 - Wikipedia

    en.wikipedia.org/wiki/PBKDF2

    DK = PBKDF2(PRF, Password, Salt, c, dkLen) where: PRF is a pseudorandom function of two parameters with output length hLen (e.g., a keyed HMAC) Password is the master password from which a derived key is generated; Salt is a sequence of bits, known as a cryptographic salt; c is the number of iterations desired; dkLen is the desired bit-length ...

  8. Distributed minimum spanning tree - Wikipedia

    en.wikipedia.org/wiki/Distributed_minimum...

    In this model, each process is modeled as a node of a graph. Each communication channel between two processes is an edge of the graph. Two commonly used algorithms for the classical minimum spanning tree problem are Prim's algorithm and Kruskal's algorithm. However, it is difficult to apply these two algorithms in the distributed message ...

  9. Avalanche effect - Wikipedia

    en.wikipedia.org/wiki/Avalanche_effect

    In cryptography, the avalanche effect is the desirable property of cryptographic algorithms, typically block ciphers [1] and cryptographic hash functions, wherein if an input is changed slightly (for example, flipping a single bit), the output changes significantly (e.g., half the output bits flip).
