FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Key management refers to management of cryptographic keys in a cryptosystem. This includes dealing with the generation, exchange, storage, use, crypto-shredding (destruction) and replacement of keys. It includes cryptographic protocol design, key servers, user procedures, and other relevant protocols.

Detailed explanation-2: -The main approaches to key management are key predistribution, key transport, key arbitration, and key agreement [22].

Detailed explanation-3: -Key Management is the process of putting certain standards in place to ensure the security of cryptographic keys in an organization. Key Management deal with the creation, exchange, storage, deletion, and refreshing of keys. They also deal with the members access of the keys.

Detailed explanation-4: -Symmetric, or secret key encryption, uses a single key for both encryption and decryption. Symmetric key encryption is used for encrypting large amounts of data efficiently. 256-bit AES keys are symmetric keys. Asymmetric, or public/private encryption, uses a pair of keys.

Detailed explanation-5: -Overview. AWS Key Management Service (KMS) gives you centralized control over the cryptographic keys used to protect your data. The service is integrated with other AWS services making it easier to encrypt data you store in these services and control access to the keys that decrypt it.
