nist cryptography

First, data encryption methodEncryption is divided into: one-way encryption, symmetric encryption and public key cryptography.1. Symmetric encryptionSymmetric encryption: Using the encryption method of single-key cryptosystem, the same key can be used as the encryption and decryption of information, which is called symmetric encryption, also known as single-key encryption. The algorithms commonly used in symmetric

The role of data encryption in our lives has become increasingly important, especially given the large number of transactions and data transmissions that occur on the web. If you are interested in adopting security measures, you will also be interested in understanding the range of security features provided by PHP. In this article, we will describe these features and provide some basic usage so that you can add security features to your application. Preparatory knowledge before detailing the se

using multi-disciplinary joint inquiry method.Take the quantum cipher as an example, since the birth of human civilization, there is a need for secrecy. For thousands of of years, secrecy and spy, like Spears and shields, are shadow, and the struggles between them have never ceased, and the advent of quantum cryptography will theoretically be the terminator of this struggle.Modern cryptography is based on

Data encryption has become more and more important in our lives, especially considering the large amount of data that has been traded and transmitted over the Internet.

Continuous mathematics and discrete mathematics are useful mathematics! The above is mainly from the mathematical point of view. From the computer point of view, the main research fields of theoretical computer science currently include: Computational Theory, algorithm design and complexity analysis, cryptography and i

based on different requests and different sending/receiving: ICT, NICT, ist, and NIST. ICT refers to the invite client transaction, which is the initiator of the session invitation. NICT refers to non-invite client transaction, which is the initiator of a non-invited session. Ist refers to the invite server tranaction and the receiver of the session invitation. NIST refers to non-invite server transaction,

Domestic textbook PairsFull Binary TreeDefinition: A depth of k and 2 ^ K-1 nodes of the binary tree called full binary tree. ---- Yan Weimin "data structure (C language version)" 124 page That is, a saturated binary tree. It can also be defined as follows: A binary tree that meets both of the following conditions is called a full Binary Tree: (1) Each node has either two subnodes or no subnodes; (2) leaf nodes can only appear on the last layer. Is a full binary tree that meets the definition o

The LaTeX of the reference is very convenient, I used several times, some experience, write out for everyone Reference. Of course, his skill is not deep enough, some local problems solved on the stop, no scrutiny. LaTeX The reference to the processing of a number of advantages: 1.

I. Background knowledge The Data Encryption Standard DES Algorithm was promulgated in 1977. Its 56-bit long cipher space is becoming more and more uncomfortable in the fast development of chip technique and computing technology. The September 1997 American Institute of National Standards and Technology (NIST) proposed a new encryption Standard---AES (Advanced encryption Standard) as a 20th century encryption standard technology instead of DES. The ob

cryptography, you can skip this part. Cryptography can be widely described as the research and experiment on encryption/decryption. encryption is a process of converting easy-to-understand data into easy-to-understand data, decryption is the process of converting obscure data into original understandable data. An obscure document is called a password, and an easy-to-understand document is called a plainte
