The proposed pseudo random bit generator uses Rubik's cube, chaotic map and
cryptographic hash function for bit generation.
Third, blocks are linked in chronological order using a
cryptographic hash function that securely connects each block to previous and subsequent blocks.
These systems use a
cryptographic hash function. The security of these digital signature systems is based on the collision resistance of the hash functions that they use [3,4].
The ZRTP KDF was a
cryptographic hash function that creates a key of length "length of key'.
SHA-256 is a one-way
cryptographic hash function, which when used in conjunction with other cryptographic algorithms, such as a digital signature algorithm, enables a number of crucial network security services or operations.
Among the topics discussed are: automatic intrusion detection and secret multi agent preservation using authentication measurement network threat; a high level view of
cryptographic hash function; a crime profiling system based on self-organizing map; biometric security; data hiding schemes based on singular value decomposition; a Malay language text-based anti-spam system using a neural network; the impact of big data on security; trust determination in wireless ad hoc networks; security impacts on social media platforms; and security in digital images.
The process, called "mining" in the Bitcoin vernacular, involves repeatedly running a computationally intensive mathematical function (called a
cryptographic hash function) on a set of randomly seeded inputs until a specific pattern pops up.
(vii) Calculate the hash value of [m.sub.i] by using a
cryptographic hash function h (e.g., SHA) and store h([m.sub.i]).
where HMAC_SHA3 is a
cryptographic hash function and function 'First' truncates a message to the first 64 bits.
A
cryptographic hash function must satisfy additional properties in order to be able to withstand all known types of cryptanalytic attack: 1) Preimage resistance: given a hash value it should be computationally difficult to find any message that has a given hash value.
