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

Ability to manage and track point-in-timeG. Client-side processing Public/private key. There are two methods that are commonly used to encrypt and decrypt data:A. Symmetric encryption: It is a special method of d

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),

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.

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,

), 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

Generally, the certificate includes the key validity period, the name of the issuing authority (Certificate Authority), and the certificate serial number. It is issued by a ca, also known as the Certificate Authority Center. As a trusted third party in e-co

Phase of IKE, So we focus on the first Phase of IKE and how the Authentication both peer occurs. The pre-share key is not discussed here. Both sender and handler er have received a certificate from the same certification authority (CA). both the sender and handler er have a copy of the CA's public key. When we build a PKI architecture, we usually install the CA

the public key of a to encrypt the data, B does not know whether the obtained public key is really from a, the same a decryption signature when the public key of B is not determined whether the public key is actually derived from B, which is dangerous in data transmission, there will be a third-party insertion in the transmission process, But both sides of the data do not know. This is a man-in-the-middle attack. To compensate for this danger, a third party's presence is required to verify the
