Public Key Infrastructure certificatesPublic key infrastructure certificates (PKI)
Public Key Infrastructure (PKI) operates by using a combination of hardware, software, policies, and procedures to manage digital certificates and public-key encryption. It involves a trusted Certificate Authority (CA) that issues digital certificates to verify the identity of entities, allowing secure communication. Users generate a pair of keys: a public key, which is shared widely, and a private key, kept secret. PKI ensures the integrity, authentication, and non-repudiation of data through cryptographic techniques, enabling secure transactions over unsecured networks.
A CA domain is known as an entity that issue digital certificates. These digital certificates certifies the ownership of a public key by the names subjects of the certificate.
Type your answer here... Serial Number and IssuerAnswer Explanation: Digital certificates in a PKI have nine required fields, two of which are the Serial Number and Issuer fields. The Serial Number is an identification number for the certificate. The name of the organization that issued the certificate is required in the Issuer field. Other required fields include the following: Version, Algorithm ID, Validity, Subject, Subject Public Key Info, the digital signature of its issuer, and an algorithm identifier.

A digital certificate is an electronic document used to prove the ownership of a public key, often as part of a public key infrastructure (PKI). It typically contains information about the key, the identity of its owner, and the digital signature of the certificate authority (CA) that issued it. Digital certificates are essential for secure online communications, enabling encryption and authentication in various applications like SSL/TLS for websites. They help ensure that data exchanges are secure and that the parties involved are who they claim to be.
Public infrastructure is infrastructure that is owned by the public or is for public use. It is generally distinguishable from private or generic infrastructure in terms of policy, financing, purpose.
The concept of a public key infrastructure is quite complicated. It is basically a combination of hardware, software, policies, procedures and people which combined together manage a digital certificate. It is explained in some detail on Wikipedia.
