Algorithm - Wikipedia

WebIn mathematics and computer science, an algorithm (/ ˈ æ l ɡ ə r ɪ ð əm / ()) is a finite sequence of rigorous instructions, typically used to solve a class of specific problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing.More advanced algorithms can use conditionals to divert the code … WebThe deterministic encryption algorithm ensures that a given input value always encrypts to the same output value each time the algorithm is executed. While deterministic encryption provides greater support for read operations, encrypted data with low cardinality is susceptible to frequency analysis recovery. bl21 iptg induction

Deterministic Encryption using AES - Cryptography Stack Exchange

In computer science, a deterministic algorithm is an algorithm that, given a particular input, will always produce the same output, with the underlying machine always passing through the same sequence of states. Deterministic algorithms are by far the most studied and familiar kind of algorithm, as well as one of the most practical, since they can be run on real machines efficiently. Formally, a deterministic algorithm computes a mathematical function; a function has a unique v… WebThe deterministic encryption algorithm guarantees that the encrypted output of a value remains static. This allows queries for a specific value to return meaningful results at the cost of increased susceptibility to frequency analysis recovery. The deterministic encryption algorithm therefore meets both the encryption and queryability ... WebFor example, encryption schemes that encrypt only secret key material (e.g., key encapsulation or Key Wrap schemes) can be considered under an entropic security definition. A practical application of this result is the use of deterministic encryption algorithms for secure encryption of secret key material. bl-2200h-pc
