Abstract: An air conditioner, especially to an apparatus for redirecting wind in an indoor unit of the air conditioner is disclosed. A scroll guide provided so as to form an air duct at the circumference of a centrifugal fan for sucking and discharging the interior air so that the interior air can pass through a heat exchanger is installed in a rotation controllable state. Wind direction patterns can be regulated in various states by rotating the scroll guide by a predetermined angle and converting the setting position of an air discharge opening according to the operation mode. The degree of freedom relative to wind redirection of the discharge air can be improved by a variable air duct and the product efficiency and the reliability can be improved through improvement of the wind amount efficiency and reduction of noise.

Abstract: An encryption key management method for mobile terminals for providing at least one mobile terminal which is connected to a network to use services with an encryption key required for issuing a certificate which is needed for the services and managed by a certification authority by using an encryption key management server is provided. The method includes operations of: a registration requesting operation where the mobile terminal generates an encryption key registration request; an encryption key managing operation where the encryption key management server generates and manages the encryption key in response to the encryption key registration request; a transferring operation of sending the generated encryption key to the mobile terminal; and a security service providing operation of receiving the certificate managed by the certification authority and providing selective security services specific to the content of the services provided to the mobile terminal.

Abstract: A message security processing system and method for Web services are provided. In the message security processing system in which messages are exchanged between a client and a server with a SOAP-RPC format, each of the client and the server includes: a security interface allowing information related to digital signature, encryption, and timestamp insertion to be set in a security context object for an application program to meet security requirements of the client or the server; a security handler receiving the security context object from the security interface, and performing security processing of a request message by calling security objects stored in a request queue of the security context object one by one in order or performing security processing of a response message by calling security objects stored in a response queue of the security context object one by one in order; and an XML security unit supporting an XML security functions by called by the security handler.

Abstract: Disclosed is an integrated security information management system and method.

Abstract: The invention relates to an apparatus and method for detecting an illegitimate change of web resources, and more particularly, to an apparatus and method for detecting an illegitimate change of web resources, which is capable of detecting whether or not HTML, XHTML and XML documents, general text documents, binary data of graphic files linked to HTML document and the like are illegitimately changed using XML digital signature and XML encryption when inquiring corresponding web page. It is characteristic of the present invention to confirm in real time whether or not the web page is illegitimately changed by inserting an illegitimate change detecting information into the web page by a web server administrator and executing corresponding web page through a web browser by a user.
