Abstract
Methods of securely authenticating a host to a storage system are provided. A series of authentication sessions are illustratively performed. Each of the authentication sessions includes the host transmitting an authentication request to the storage system. The storage system authenticates the host based at least in part upon a content of the authentication request. After each successful authentication of the host to the storage system, an encryption key that was utilized in encrypting the authentication request that was transmitted to the storage system is deleted. After each encryption key deletion, a new encryption key that is different than the previous key is optionally stored and is utilized in the next authentication session.
