Abstract
Disclosed is an electronic device that selects a password and encrypts it utilizing a public key of a public/private encryption key pair. The electronic device then provides the encrypted password to a client device when an access request is received from the client device. The client device proceeds to obtain an unencrypted version of the password by submitting the encrypted password to a private key server (which utilizes the private key of the public/private encryption key pair to decrypt the password) and receiving the decrypted password in return. The client device then returns the password to the electronic device which, upon receiving the decrypted password, allows access from the client device. The device generates the password once during operation or each time an access request is received.
