With the rapid development of e-commerce, information security has become one of the key issues, especially the requirements of online payment and online banking for information security. In order to carry out secure e-commerce activities on the Internet, public key infrastructure (PKI) has been widely used at home and abroad. Do we really need PKI? What is the use of P

John Morello's column contains prerelease information that may change.
The Public Key Infrastructure (or PKI) is a basic element for building trust between different applications, operating systems, and identity recognition fields. It is built on a hierarchical trust model. In this model, the final entity trusts the highest root level public key, so it implicitly trusts any ot
PKI (public Key Infrastructure) is a combination of software that uses encryption technology, processes, and services to help companies protect their communications and business transactions. A PKI is a system consisting of digital certificates, CAS, and other registered authorities. When an electronic transaction occurs, the PKI confirms and certifies the validi
PKI Public Key Infrastructure is a system or platform that provides public-key cryptography and digital signature services to manage keys and certificates. An organization can establish a secure network environment by using the PKI framework to manage keys and certificates.PKI mainly consists of four parts: Certificates in the form of X-V3 and certificate revocation List CRL (V2), CA operation Protocol, CA
PKI is the initial acronym of Public Key Infrastructure, which is the key infrastructure; PKI is a standard technology and specification to use public key cryptography to provide a set of security foundation platform for e-commerce development.
In the Privilege standard, the PKI is defined as an infrastructure that supports public key management and can support
PKIIs a new security technology, which consistsPublic KeyCryptographic technology, digital certificates, certificate issuing authority (CA), and security policies for public keys. PKI is a system that uses public key technology to implement e-commerce security. It is an infrastructure that ensures security through network communication and online transactions. In a sense, PKI includes securityAuthentication
PKI core-Certification Center CA) Introduction
To ensure the transmission security of online digital information, in addition to using stronger encryption algorithms and other measures in communication transmission, a trust and trust verification mechanism must be established, that is to say, all parties involved in e-commerce must have a verifiable identity, which is a digital certificate. Digital Certificates are the identity certificates used by en
), through the hashing algorithm, transformed into a fixed-length output, the output is the hash value. This conversion is a compression map, that is, the space of the hash value is usually much smaller than the input space, the different inputs may be hashed to the same output, but not from the hash value to uniquely determine the input value. Simply, a function that compresses messages of any length to a message digest of a fixed length. Common algorithms? SHA-1, SHA-256 , MD5, MD2Characteris
digitally signed.We find that both symmetric and asymmetric cryptographic algorithms have their advantages and disadvantages, so the solution is to use asymmetric encryption algorithms to encrypt the symmetric encryption calculationThe key generated by the law is very secure, and the symmetric encryption algorithm is used to encrypt the real data, which is compact, fast, and secure, which is the solution we usually use in the actual environment.Solutions. But then there is a problem, is how the

Cryptographic algorithm encryption based on PKI)
A single-key cryptographic algorithm, also known as symmetric cryptographic algorithms, refers to encryption.KeyThe same password algorithm as the decryption key. Therefore, when transmitting and processing information, the sender and receiver of information must jointly hold this password, which is called a symmetric password ). In symmetric key cryptography algorithms, encryption and decryption operat
Public Key digital signature algorithm Signature Based on PKI)
DSADigital Signature Algorithm, Digital Signature Algorithm, used as part of the Digital Signature standard), it is another public key Algorithm, it cannot be usedEncryption, Used only as a digital signature. DSA uses a public key to verify the data integrity and identity of the Data sender for the receiver. It can also be used by a third party to determine the authenticity of the signatur
Digital Certificate Based on PKI
Digital Certificates are the identity certificates for various entities (cardholders/individuals, merchants/enterprises, gateways/banks) to exchange information and conduct business activities online, all parties to the transaction need to verify the validity of the certificate of the other party, so as to solve the mutual trust problem. A certificate is a digital signature provided by the certificate authority.KeyThe
With the rapid development of network technology, Internet has become an indispensable part of people's lives, but it also faces installation problems. To ensure that the Internet can transmit data securely, technicians have developed PKI technology.
Now let's look at the data signature for PKI.
Provides the following functions:
Identity Verification: the recipient can confirm the sender's identity

Microsoft PKI has made many improvements in Windows Server 2008 and has added many features, the first of which is certificate lifecycle management, especially with regard to automatic registration of computers and user certificates. In Windows Server 2008, Certificate Lifecycle Management is enhanced by the use of certificate roaming new features. We will describe this feature later.
