Key Management and Key Distribution in network security


Key Management

The main aim of key management is to generate a secret key between two parties and store it to prove the authenticity between communicating users. Key management is the techniques which support key generation, storage and maintenance of the key between authorized users. Key management plays an important role in cryptography as the basis for securing cryptographic goals like confidentiality, authentication, data integrity and digital signatures. It is not the case where communicating parties are using same key for encryption and decryption or whether two different keys are used for encryption and decryption. Basic purpose of key management is key generation, key distribution, controlling the use of keys, updating, destruction of keys and key backup/recovery.
