What is encryption key management?

Encryption key management refers to the systematic approach employed to handle encryption keys throughout their lifecycle. It encompasses several crucial functions, including the generation of keys, their distribution to authorized users, and the implementation of strategies to secure these keys from unauthorized access or misuse.

Effective key management is essential because encryption keys are the foundation of secure communications. If an unauthorized party gains access to a key, they can decrypt sensitive information, undermining the whole purpose of encryption. Therefore, the ability to generate strong keys, distribute them securely, and ensure their protection is vital for maintaining the confidentiality, integrity, and authenticity of data.

The other options involve aspects of cybersecurity but do not specifically address the comprehensive process of handling encryption keys. Blocking unauthorized network access, encoding messages, and managing internet security protocols are all important elements of cybersecurity, but they do not capture the full scope of encryption key management, which is primarily focused on the lifecycle of encryption keys themselves.
