Abstract:
A secure login method to enhance security in a network computer system having at least one server computer coupled over a communication network to a plurality of client computers comprising:sending a login request and an encrypted public key form a first processor to a second processor to obtain KEK from the second processor, first and second processor communicating to generate a session key for use in privately encrypted communication between the first and second processor, wherein the sending of the login request and the encrypted public key from the first processor comprises computing a hash value using a user password and encrypting the public key with the hash value; and first and second processor communicating to generate a persistent storage key for use in communicating with persistent storage, wherein the first and second processor communicating to generate the persistent storage key for use in communicating with persistent storage further comprises locating the first split persistent storage key at the second processor and sending the first split persistent storage key to the first processor, wherein a second split persistent storage key is generated at the first processor, wherein the first and second split persistent storage keys are combined at the first processor to produce a persistent storage key for communication between the first processor and a persistent storage.
