Investigate about SHA-3 algorithm, describe its characteristics and requirements.
Answers
Explanation:
Characteristics of SHA-3 Algorithm:
- The output length is small as compared to that of entered input
- Computation through this algorithm is fast and very efficient for any kind of input
- Any change done to the input will affect lots of output bits
- One-way value: The input cannot be directly determined from the output
- Strong collision resistance: Two different inputs can't have the same output
Answer:
Investigation of the SHA 3 Algorithm has been mentioned here below:-
Explanation:
In brief, SHA 3 is abbreviated form for Secure Hash Algorithm – 3. It is also one of the latest developments by SHA and was officially released in 2015 Aug. 5th by NIST. When comparing with its previous versions, it is obvious that SHA 3 is much distinct as compared to SHA 1 or SHA 2.
Main characteristics of SHA 3 are mentioned here:-
1. It is also considered as a part of the broader cryptographic Keccak family and so it is obvious that it offers with additional benefits and functions including authenticated encryption system.
2 It also offers with a much improved faster hashing for architects along with AEAD functionality.
3. some other features may include random permutation, squeezing output for bigger volume of data and pseudorandom function.
4. in terms of flexibility, SHA 3 is more flexible as compared to earlier versions.
4. For security, SHA 3 is more conservative with more number of rounds increased from 12 + l to around 12 + 2l.
