Abstract
A data encryption method for an IEEE 1394 serial bus network, a data encryption method for an IEEE 1394 serial bus network, comprising the steps of requesting a private encryption at a data transmission node using a predetermined encryption algorithm at a data receiving node; recognizing and confirming that the data transmission node set the private encryption requesting at the data receiving node; transmitting an encrypted data at the data transmission node when the receiving node requests a service at the data transmission node; and decoding the encrypted data using a predetermined unencrypting key at the data receiving node, for thereby transmitting an encryption algorithm and encryption data to a corresponding node when a service is requested from a receiving node with respect to a certain system by setting an encryption algorithm in the system and decoding an encrypted data transmitted from the system in accordance with an encryption algorithm and displaying the same, so that a certain user can use a service.
