Description: Host identification is a fundamental process in public key infrastructure (PKI) that allows for the recognition and authentication of devices within a network. This process is based on assigning a unique identifier to each host, which can be a server, computer, or any other connected device. Host identification ensures that communications and transactions within the network are conducted securely, preventing identity spoofing and ensuring data integrity. In the context of PKI, host identification is carried out through digital certificates, which are issued by a certificate authority (CA). These certificates contain information about the host’s identity as well as its public key, allowing other devices to verify its authenticity. Host identification is crucial for establishing secure connections across various protocols, including those used for encrypted communications. Additionally, this process is essential for access management and the implementation of security policies in networks, where strict control over the devices that can connect and communicate with each other is required.
