In computer science, cryptography refers to secure information and communication techniques derived from mathematical concepts and a set of rule-based calculations calledalgorithms, to transform messages in ways that are hard to decipher. These deterministic algorithms are used for cryptographic key generati...
In the digital era, the goal of cryptography remains the same: to prevent information exchanged between two parties being swiped by an adversary. Computer scientists often refer to the two parties as “Alice and Bob,” fictional entities first introduced in a 1978 article describing a digital enc...
Computer architecture is a specification describing how computer software and hardware connect and interact to create a computer network. It determines the structure and function of computers and the technologies it is compatible with – from the central processing unit (CPU) to memory, input/output ...
Cryptology, which encompasses both cryptography and cryptanalysis, is deeply rooted in computer science and advanced mathematics. The history of cryptography dates back to ancient times when Julius Caesar created the Caesar cipher to obscure the content of his messages from the messengers who carried th...
Cryptography is the process of hiding or coding information so only the intended recipient can read a message. Discover how cryptography works and the potential risks it poses.
So, what is computer science? Generally speaking, computer science is the study of computer technology, both hardware and software. However, computer science is a diverse field; the required skills are both applicable and in-demand across practically every industry in today's technology-dependent wo...
Modern cryptography exists through the combination of advanced mathematics, computer science, communication, and engineering processes. Computers and operating systems use complex encryption methods to encode messages so only authorized parties can see them. The message, or plaintext, is converted into cip...
According to American cryptographer and computer security expert Bruce Schneier, cryptography is “the art and science of keeping messages secure.”The cryptography method transforms plain text into encrypted text (aka ciphertext) using the encryption key, and the target receiver can decrypt it using ...
Ethical hacking is use of hacking techniques by friendly parties in an attempt to uncover, understand and fix security vulnerabilities in a network or computer system.
leverage parallelism can achieve significant speedup, especially in tasks involving large datasets or complex computations. parallelized algorithms exploit the power of multiple processors, making them well-suited for addressing challenges in optimization problems. does parallel computing have cryptography ...
