Method of generating an encryption key without use of an input device, and apparatus therefor
First Claim
1. An encryption key generating method performed in a network environment including a host system that transmits an encrypted signal and a client system that receives the encrypted signal and decrypts the received signal by using an encryption key established in the host system, the encryption key generating method comprising:
- reading a pre-designated number corresponding to the host system;
reading a current value of a dip switch installed in the host system;
associating the pre-designated number with the current value to generate an associated value; and
generating an encryption key in a wireless LAN environment by using the associated value.

Abstract
A method of generating an encryption key in a host system that transmits an encrypted signal. The encryption key generating method can be used in a host system that doesn'"'"'t have an input device such as a keyboard or mouse. The encryption key generating method can be used in a network environment having a host system that can transmit an encrypted signal and a client system that can receive and accept the encrypted signal by using an encryption key determined in the host system. The method can include the acts of reading a pre-designated number of the host system, reading a current value of a dip switch installed in the host system, associating the pre-designated number with the current value, and generating an encryption key in a wireless LAN environment by using the associated value. Since the encryption key generating method generates an encryption key by using the pre-designated number of the host system which is unique to each system and not externally exposed, and also increases the number of possible encryption keys by using the dip switch, increased security can be achieved.
