Final answer:
The correct answer is C) Public Key Infrastructure (PKI), which is the framework used for the issuance and management of asymmetric keys and digital certificates.
Step-by-step explanation:
The system and processes used to issue and manage asymmetric keys and digital certificates are known as Public Key Infrastructure (PKI). Contrary to the other options listed:
- Key Management System pertains to the management of cryptographic keys in a cryptosystem.
- Certificate Authority is an entity that issues digital certificates.
- Encryption Control Hub is not a standard term in the context of cryptographic operations and key management.
Therefore, the correct answer is C) Public Key Infrastructure (PKI). PKI is a framework that provides services and standards to enable secure electronic transactions over the internet, through the use of a pair of keys known as a public key and a private key. These keys are used to encrypt and decrypt messages, authenticate identity, and ensure data integrity.
