5th Chapter-PKI and Certificate Service Application First, public key infrastructure (1), what is a PKI ØPKI (public key infrastructure, PKI) is a technology that ensures information security by using public key technology and digital signatures, and is responsible for verifying the identity of a digital certificate holder Ø In a

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

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

The X509 standard defines PKI as an infrastructure that supports public key management and supports authentication, encryption, integrity, and auditable services.P2 mentioned that PKI is an infrastructure. Its goal is to make full use of the theoretical basis of public key cryptography and establish a universally applicable infrastructure, provides comprehensive security services for various network applica

Windows has been providing robust, platform-wide support for public Key Infrastructure (PKI) since Windows 2000. This version contains the first native certification authority feature, introduces autoenrollment, and provides support for smart card authentication. In Windows XP and Windows Server 2003, these features have been extended to provide more flexible enrollment options through version 2 certificate templates, and to support autoenrollment of

This article is a detailed analysis of the PKI encryption Technology (OpenSSL) in PHP, which requires a friend's reference The code is as follows: generate private key and public key genrsa-out PRIVATE-RSA.PEM rsa-in Private-rsa.pem-pubout-out Pubic-rsa.cer

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 digital certificate on the entity, then the CA certificate is actually the CA Public Key;

Current Cisco VPN technologies, such as point-to-point IPsec, IPsec/GRE, DMVPN, GETVPN, and EzVPN, use IKE as underlying protocol for authenticated key exchange. all the vpn technologies of cisco currently use the IKE protocol. The IKE protocol is a hybrid of the Oakley and SKEME protocols and operates inside a framework defined by Internet Security Association and Key Management Protocol(ISAKMP) the IKE protocol itself is a hybrid protocol, which is composed of Oakley and SKEME and ISAKMP.
