Delegated Path Discovery
Delegated Path Discovery (DPD) is a method for querying a trusted server for information about a public key certificate. DPD allows clients to obtain collated certificate information from a trusted DPD server Server may refer to: Computing *Server (computing), a computer program or a device that provides requested information for other programs or devices, called clients. Role * Waiting staff, those who work at a restaurant or a bar attending custome .... This information may then be used by the client to validate the subject certificate. The requirements for DPD are described in RFC 3379. See also * Delegated Path Validation * SCVP References Cryptographic protocols {{crypto-stub ...

Public Key Certificate
In cryptography, a public key certificate, also known as a digital certificate or identity certificate, is an electronic document used to prove the validity of a Key authentication, public key. The certificate includes the public key and information about it, information about the identity of its owner (called the subject), and the digital signature of an entity that has verified the certificate's contents (called the issuer). If the device examining the certificate trusts the issuer and finds the signature to be a valid signature of that issuer, then it can use the included public key to communicate securely with the certificate's subject. In email encryption, code signing, and Electronic signature, e-signature systems, a certificate's subject is typically a person or organization. However, in Transport Layer Security (TLS) a certificate's subject is typically a computer or other device, though TLS certificates may identify organizations or individuals in addition to their core rol ...

Client (computing)
is a computer that gets information from another computer called server in the context of client–server model of computer networks. The server is often (but not always) on another computer system, in which case the client accesses the service by way of a network. A client is a program that, as part of its operation, relies on sending a request to another program or a computer hardware or software that accesses a service made available by a server (which may or may not be located on another computer). For example, web browsers are clients that connect to web servers and retrieve web pages for display. Email clients retrieve email from mail servers. Online chat uses a variety of clients, which vary on the chat protocol being used. Multiplayer video games or online video games may run as a client on each computer. The term "client" may also be applied to computers or devices that run the client software or users that use the client software. A client is part of a cl ...

Server (computing)
A server is a computer that provides information to other computers called " clients" on a computer network. This architecture is called the client–server model. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients or performing computations for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device. Typical servers are database servers, file servers, mail servers, print servers, web servers, game servers, and application servers. Client–server systems are usually most frequently implemented by (and often identified with) the request–response model: a client sends a request to the server, which performs some action and sends a response back to the client, typically with a result or acknowledgment. Designating a computer as "server-class hardwa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delegated Path Validation
Delegated Path Validation (DPV) is a cryptographic method used to offload the task of validating the certification path of digital certificates from the client to a trusted server. This process is integral to various security protocols that rely on Public Key Infrastructure (PKI). DPV aim to enhance the efficiency of certification path validation by leveraging a server dedicated to this task, which provides validation results to the client. This approach is particularly useful in resource-constrained environments where clients may not have the computational power to perform extensive certificate validation themselves.

Certificate path validation Certificate path validation is a crucial process in PKI that ensures the authenticity and trustworthiness of a digital certificate. This process is standardized in and involves verifying a chain of certificates, starting from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SCVP
The Server-based Certificate Validation Protocol (SCVP) is an Internet protocol for determining the path between an X.509 digital certificate and a trusted root (Delegated Path Discovery) and the validation of that path (Delegated Path Validation) according to a particular validation policy. Overview When a relying party receives a digital certificate and needs to decide whether to trust the certificate, it first needs to determine whether the certificate can be linked to a trusted certificate. This process may involve chaining the certificate back through several issuers, such as the following case: Equifax Secure eBusiness CA-1 ACME Co Certificate Authority Joe User Currently, the creation of this chain of certificates is performed by the application receiving the signed message. The process is termed "path discovery" and the resulting chain is called a "certification path". Many Windows applications, such as Outlook, use Cryptographic Application Programm ...
