WebPost-Quantum Cryptography: Cryptographers are working on developing new cryptographic systems that are resistant to attacks by quantum computers. These systems are known as Post-Quantum Cryptography (PQC). PQC includes schemes based on lattice-based cryptography, code-based cryptography, hash-based cryptography, and others. WebHistorically, cryptography was split into a dichotomy of codes and ciphers; and coding had its own terminology, analogous to that for ciphers: " encoding, codetext, decoding " and so on. However, codes have a variety of drawbacks, including susceptibility to cryptanalysis and the difficulty of managing a cumbersome codebook.

Encryption Algorithms Explained with Examples

In cryptology, a code is a method used to encrypt a message that operates at the level of meaning; that is, words or phrases are converted into something else. A code might transform "change" into "CVGDK" or "cocktail lounge". The U.S. National Security Agency defined a code as "A substitution cryptosystem in which the plaintext elements are primarily words, phrases, or sentences, and th… WebThere have been three well-defined phases in the history of cryptology. The first was the period of manual cryptography, starting with the origins of the subject in antiquity and continuing through World War I. Throughout this phase cryptography was limited by the complexity of what a code clerk could reasonably do aided by simple mnemonic devices. …
