Examples of Cryptographic hash in a sentence

  • Message integrity: Cryptographic hash functions, message authentication code, CBC MAC and its security, Cryptographic hash functions based MACs, Case study: SHA512, SHA3, Merkle trees.

  • Cryptographic hash functions can be used as building blocks in key derivation functions (KDFs) (e.g., as specified in [SP 800-56A], [SP 800-56B] and [SP 800-108]).

  • Cryptographic hash functions are amongst the most-studied and most-used cryptographic functions.

  • Cryptographic hash functionA function that maps a bit string of arbitrary length to a fixed length bit string and is expected to have the following three properties:1.

  • UNIT IV : Cryptographic Hash Functions & Digital SignaturesObjectives: Present overview of the basic structure of cryptographic functions, Message Authentication Codes, Understand the operation of SHA-512, HMAC, Digital Signature Application of Cryptographic hash Functions, Requirements & Security, Secure Hash Algorithm, Message Authentication Functions, Requirements & Security, HMAC & CMAC.

  • They have:• Symmetric encryption.– Encryption: Enc(K, m).– Decryption: Dec(K, c).• Cryptographic hash function: Hash(m).• MAC: MAC(K, m).They share a symmetric key K and know each other’s public key.

  • Cryptographic hash functions are mathematical operations run on digital data; by comparing the computed "hash" (the output from execution of the algorithm) to a known and expected hash value, a person can determine the data's integrity.

  • Cryptographic hash functions can be used as building blocks in key derivation functions (KDFs) (e.g., as specified in SP 800-56A, SP 800-56B, SP 800-56C and SP 800-108).The KDFs specified in SPs 800-56A and B use the hash functions either directly, or indirectly in an HMAC construction.

  • Cryptographic hash functions can be used in a broad range of applications: to compute a short unique identifier of an input string (for a digital signature as mentioned above), as one-way functions to hide an input string (e.g. for passphrase protection), to commit to a string in a protocol, for entropy extraction and for key derivation.

  • For each interim, complete or completed vehicle2.1. Input data and input information as set out for the complete or completed vehicle in Annex III and which was provided by the particular manufacturer2.2. Software information2.2.1. Simulation tool version ………..2.2.2. Date and time of the simulation ………..2.3. Cryptographic hashes2.3.1. Cryptographic hash of the vehicle information file ………..
