WebAug 11, 2024 · The image encryption scheme has a symmetric key structure and contains plain-text permutation and bidirectional diffusion processes. Experimental results and security analyses prove that it has excellent robustness against various possible attacks. Download to read the full article text References Chen M, Mao S, Liu Y. Big data: A survey. WebMay 1, 2024 · Encryption is encoding messages with the intent of only allowing the intended recipient to understand the meaning of the message. It is a two way function (you need to be able to undo whatever scrambling you’ve done to the message). This is designed to protect data in transit.

WebAn SSL certificate protects your privacy by encrypting the data between a client (usually a web browser) and a web server. Thus, it prevents an ill-intended third party from stealing and tampering with the data in transit. Such security is necessary to protect users’ sensitive data such as credit card information, passwords, personal messages, etc. WebThere are various types of public-key cryptography, but the most famous one is RSA. The RSA is totally based on the number theory. The RSA can be used in file encryption, …

Discrete logarithms are quickly computable in a few special cases. However, no efficient method is known for computing them in general. Several important algorithms in public-key cryptography, such as ElGamal base their security on the assumption that the discrete logarithm problem over carefully … See more In mathematics, for given real numbers a and b, the logarithm logb a is a number x such that b = a. Analogously, in any group G, powers b can be defined for all integers k, and the discrete logarithm logb a is an integer k such that … See more Powers of 10 The powers of 10 are $${\displaystyle \ldots ,0.001,0.01,0.1,1,10,100,1000,\ldots .}$$ For any number a in this list, one can compute log10 a. For example, log10 10000 = 4, and … See more While computing discrete logarithms and factoring integers are distinct problems, they share some properties: • both are special cases of the hidden subgroup problem for finite abelian groups, • both problems seem to be difficult (no efficient See more Let G be any group. Denote its group operation by multiplication and its identity element by 1. Let b be any element of G. For any positive integer k, the expression b denotes the product of b with itself k times: See more Powers obey the usual algebraic identity b = b b . In other words, the function $${\displaystyle f\colon \mathbf {Z} \to G}$$ defined by f(k) = b is a See more The discrete logarithm problem is considered to be computationally intractable. That is, no efficient classical algorithm is known … See more There exist groups for which computing discrete logarithms is apparently difficult.
