PURPOSE: A security remote booting system is provided to remotely control a booting of a CD(Cash Dispenser) or an ATM(Automatic Teller Machine) mounted in a remote place by a security protocol and change and modify through a financial network by replacing a central computer once. CONSTITUTION: A power on command/response signal is transmitted between a host computer(10) and a CD or ATM(20) interactively. A secret number(ID), inherent secret key data(Key), and date data(Date) are coded as a public key(PK) of the CD or ATM(20). The secret number(ID) and the date data(Date) are checked, and the secret number(ID) is coded as a Key. A kernel(Kernel) and a hash function(h(Kernel)) are coded. The CD or ATM(20) loads a kernel, and compares the hash function(h(Kernel)) value with a stored data value. If the hash function(h(Kernel)) value is identified with a stored data value, the hash function(h(Kernel)) value is transmitted to the host computer(10).
