Description: Entity management in the context of Public Key Infrastructure (PKI) refers to the process of managing and controlling the entities involved in the creation, distribution, and revocation of digital certificates. This includes identifying users, devices, and services that require authentication and encryption. Entity management involves creating security policies, assigning roles and responsibilities, and implementing procedures to ensure that entities are verifiable and trustworthy. Additionally, it focuses on integrating systems that allow for the efficient management of certificates, ensuring that entities are properly registered and that their credentials are valid and up-to-date. This process is fundamental to maintaining the integrity and security of digital communications, as it ensures that only authorized entities can access sensitive resources and perform secure transactions. Entity management also encompasses version control of certificates, ensuring that updates and changes are properly recorded, which is crucial in environments where security is a priority. In summary, entity management is an essential component of PKI, enabling effective administration of digital identity and trust in online interactions.
