Definition Edit

Key management/exchange is

[a] method of electronically transmitting, in a secure fashion, a secret key for use with a secret-key cryptographic system. Key management can be used to support communications privacy. This method can be accomplished most securely with public-key cryptographic systems, which do not require the sharing of secret keys with third parties. Instead, a secret key is encrypted with a recipient’s public key, and the recipient decrypts the result with his/her private key to receive the secret key. A variation of key management that is based on key exchange does not require encrypting the secret key.[1]
