In the first chapter, we will discuss the four security services and the related algorithms. In the second chapter, we will discuss the next generation of cryptography algorithms which may be implemented in the future.University of Alberta (Canada).Yeung, Freddy Lap Kei....
What Kerckhoffs and Shannon are getting at is that you want to design an algorithm that doesn’t need to be a secret in order to successfully conceal information. That said, in today’s world, the public nature of cryptographic algorithms is seen as something good in and of itself...

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...
Despite these drawbacks, however, symmetric-key cryptography does have a place in computer security. As it turns out, symmetric-key algorithms are the simplest, fastest cryptographic algorithms we know of. In a world built on bandwidth, this speed is a necessity. Symmetric-key algorithms also ...
2.3 Cryptographic Algorithms There are different ways of classifying cryptographic algorithms. One is based on the number of keys used in encryption and decryption. Three types of algorithm, each of which will be briefly elaborated, are given below: • Symmetric cryptography • Asymmetric cryptograp...
