말뭉치

  1. In fact, NIST selected SHA-3 using a public contest explicitly to have a new hash standard that was not derived from the SHA family ready to go when needed.[1]
  2. This is where many of wondered why we didn’t just move from SHA-1 to SHA-3.[1]
  3. The number one reason why the world didn’t move to SHA-3 is because almost none of the world’s software or hardware supported it.[1]
  4. On top of that, SHA-3 was a relative new-comer when the SHA-2 migration plans were being figured out.[1]
  5. The SHA-3 function has no predefined output length.[2]
  6. All SHA-3 types use a Keccak sponge function.[2]
  7. In this case, as the SHA3-256 output hash length is less than 1088 bits, the squeezing phase does not need any iteration functions.[2]
  8. Essentially, the secure hash uses a hashing algorithm such as SHA-3 to produce a fixed-length hash of the message regardless of the message length.[2]
  9. The Keccak algorithm is the work of Guido Bertoni, Joan Daemen (who also co-designed the Rijndael cipher with Vincent Rijmen), Michael Peeters, and Gilles Van Assche.[3]
  10. In 2006 NIST started to organize the NIST hash function competition to create a new hash standard, SHA-3.[3]
  11. SHA-3 is not meant to replace SHA-2, as no significant attack on SHA-2 has been demonstrated.[3]
  12. Keccak was accepted as one of the 51 candidates.[3]
  13. The authors of Keccak came up with a simple (if you understand) scheme, the so-called sponge function.[4]
  14. Inside this "sponge" there is a state(1600 bit size for SHA-3), to which one and the same function is applied on each round, which implements pseudo-random permutation.[4]
  15. The Keccak team asserts “Its throughput for a given circuit area is an order of magnitude higher than SHA-2 or any of the SHA-3 finalists.[4]
  16. Finally, SHA-3 appears to have the best resistance to quantum computing based attacks.[4]
  17. The SHA-3 standard does not differ markedly from the draft version that was released for public comment in May 2014.[5]
  18. SHA-3 is very different from SHA-2 in design," says NIST's Shu-jen Chang.[5]
  19. Keccak has been chosen as the official algorithm for SHA-3 in2012.[6]
  20. In this paper we propose a modification on the design of Secure Hash Algorithm (SHA-3) on Xilinx Field ProgrammableGate Array (FPGA) device.[6]
  21. A system based on the combination of SHA-3 and error tolerant scheme is also described.[6]
  22. Simulation resultsshows, an efficiency in area and delay of SHA-3 designs.[6]
  23. (Secure Hash Algorithm 3) is a family of cryptographic hash functions standardized in NIST FIPS 202, first published in 2015.[7]
  24. In 2007, NIST launched the SHA-3 competition to design a successor to SHA-2, in case the design turned out to be bad.[8]
  25. SHA-3 specification defines a single cryptographic hash function that is parameterized to produce hash output of certain sizes.[9]
  26. The hashing of 01 bits can be integrated into the finalization stage of a SHA-3 implementation.[9]
  27. may be useful in verifying the correctness of the SHA-3 implementation.[9]
  28. An application MAY generate signatures with SHA3-256, SHA3-384, and SHA3-512 hash algorithms.[9]
  29. The goal of the SHA-3 competition was to specify "a new hash algorithm to augment and revise" FIPS 180-2, the standard that specified SHA-1 and SHA-2.[10]
  30. The SHA-3 competition was organized by the United States National Institute of Standards and Technology (NIST).[10]
  31. A hash function formerly called Keccak, chosen in 2012 after a public competition among non-NSA designers.[11]
  32. The number of SHA-3 permutation rounds per clock cycle is configurable at synthesis time, allowing users to trade throughput for silicon resources.[12]
  33. In response to recent advances in cryptanalysis of commonly used hash algorithms, NIST USA announced a publicly open competition for selection of new standard Secure Hash Algorithm called SHA-3.[13]
  34. NIST said that while SHA-2 -- specified in FIPS 180-4, Secure Hash Standard -- is still "secure and suitable for general use," SHA-3 will complement it and provide much-needed diversity.[14]
  35. Although no attacks have yet been reported on SHA-2, it's algorithmically similar to SHA-1, hence the need for SHA-3, which is very different from SHA-2 in design.[14]
  36. In hardware implementations, Keccak was notably faster than all other finalists, and some of the SHA-3 functions can be implemented on a chip without requiring much additional circuitry.[14]
  37. The core can implement any one of the four cryptographic SHA-3 hash functions provisioned by the standards: SHA3-224, SHA3-256, SHA3-384, and SHA3-512.[15]
  38. Designers can configure the new SHA-3 Secure Hash Function Core to provide an optimum solution for a variety of application challenges.[16]
  39. “Developers wishing to build the most secure, future-looking security into their devices and systems will want to consider using SHA-3,” said Nikos Zervas, chief executive officer for CAST.[16]
  40. The new SHA-3 core is available now in synthesizable RTL for ASICs or optimized netlists for FPGAs.[16]
  41. While the SHA-2 standard continues to be secure and is safe to use, NIST believes that SHA-3 provides a greater degree of future proofing against attacks.[16]
  42. In contrast to SHA-2, SHA-3 is based on sponge construction in which data is “absorbed” into the sponge, then the result is “squeezed” out.[17]
  43. A hash function, once in the past called Keccak, picked in 2012 after a public rivalry among non-NSA originators.[18]
  44. "Developers wishing to build the most secure, future-looking security into their devices and systems will want to consider using SHA-3," said Nikos Zervas, chief executive officer for CAST.[19]
  45. Like other hash functions, fixed-length SHA-3 functions convert a digital message into a brief, fixed-length "message digest" that can act as a digital signature.[19]
  46. There's no theoretical reason for this - SHA3 wasn't created because SHA2 is weak or has any known problems.[20]
  47. Bitcoin sha3 are created as a reward for nucleotide process celebrated as mining.[20]
  48. SHA3 should complement SHA2.[20]
  49. As an addendum, the SHA3 standard was released in 2015 by the (US) National Institute of Standards and Technology (NIST).[20]
  50. Some of them was broken (like MD5 and SHA1), some are still considered secure (like SHA-2, SHA-3 and BLAKE2).[21]
  51. The SHA-3 family of functions are representatives of the "Keccak" hashes family, which are based on the cryptographic concept "sponge construction".[21]
  52. In this implementation the core functionality of SHA-3 is implemented using LUT-6 primitives and then these primitives are instantiated for the complete implementation of SHA-3.[22]
