WebMar 21, 2024 · The short-term bus passenger flow prediction of each bus line in a transit network is the basis of real-time cross-line bus dispatching, which ensures the efficient utilization of bus vehicle resources. As bus passengers transfer between different lines, to increase the accuracy of prediction, we integrate graph features into the recurrent neural … WebThe simplest way to achieve both diffusion and confusion is a substitution-permutation network. In these systems, the plaintext and the key often have a very similar role in …

WebNov 18, 2024 · The DES (Data Encryption Standard) algorithm is a symmetric-key block cipher created in the early 1970s by an IBM team and adopted by the National Institute of Standards and Technology (NIST). The algorithm takes the plain text in 64-bit blocks and converts them into ciphertext using 48-bit keys. WebIn cryptography, an initialization vector ( IV) or starting variable ( SV) [1] is an input to a cryptographic primitive being used to provide the initial state. The IV is typically required to be random or pseudorandom, but sometimes an IV only needs to be unpredictable or unique.
WebOct 22, 2024 · Diffusion is an encryption operation where the influence of one plaintext symbol is spread over many ciphertext symbols with the goal of hiding statistical properties of the plaintext. [Paar, Understanding Cryptography 1st ed., 3.1.1] WebJun 3, 2024 · A block cipher has high diffusion (information from one plaintext symbol is spread into several cipher-text symbols). It is also fairly difficult for an attacker to insert …
In cryptography, confusion and diffusion are two properties of the operation of a secure cipher identified by Claude Shannon in his 1945 classified report A Mathematical Theory of Cryptography . These properties, when present, work to thwart the application of statistics and other methods of … See more Confusion Confusion means that each binary digit (bit) of the ciphertext should depend on several parts of the key, obscuring the connections between the two. The property of … See more Designing an encryption method uses both of the principles of confusion and diffusion. Confusion means that the process drastically changes data from the input to the output, for example, by translating the data through a non-linear table created from … See more In Shannon's original definitions, confusion refers to making the relationship between the ciphertext and the symmetric key as complex and involved as possible; diffusion refers to dissipating the statistical structure of plaintext over the bulk of See more • Algorithmic information theory • Avalanche effect • Substitution–permutation network See more
