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

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

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 large direction is divided into 3 regions: 1. KMC Area (intranet) A) KMC server b) KMC Database c) En

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.

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;

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
