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 Data Int

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. A more general practice for developers is to link the

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

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;

pki-system access Policy In the PKI system, in order to the security of the system, the various parts of PKI need to be divided into different regions, and the access strategy of the firewall is added to prevent the unnecessary service access system.

The delegate Enrollment Agent feature allows you to define exactly what a registered agent can do and what not to do. It allows you to delegate a temporary smart card registration to someone, like a receptionist, in case a user throws his or her smart card home. The next added feature is called the Network Device Registration service, or SCEP, which is integrated into the local installation. This is a simple feature that allows users to register their credentials with a normal Windows installat

The online revocation service is a new component introduced in Windows Server 2008. Is the Microsoft deployment of the OCSP protocol. This feature, coupled with the new OCSP answering service, is a big boost compared to CRL based revocation. The client's OCSP client has been redesigned for the schema, plus an OCSP responder. Additionally, the OCSP method has been integrated into Kerberos and SSL. The new OCSP Responder is designed for extensibility p
