A method of supporting a login for a web service of a user terminal using a portable device is provided. The method includes registering the portable device through a wireless communication with the portable device, encrypting login information for at least one web service and transmitting the login information to the registered portable device, and transmitting a request message requesting a transmission of the login information of the web service to the portable device. The request message includes a service identification (ID) identifying the web service.

Method and apparatus for supporting login through user terminal

A method and apparatus for sharing secret information between devices in a home network are provided. In the method and apparatus, home network devices receive a password (credential) input by a user and encrypt secret information based on the credential by using keys generated according to a predetermined identity-based encryption (IBE) scheme. Accordingly, it is possible to securely share the secret information between home network devices without any certificate authority or certificate.

Method of and apparatus for sharing secret information between device in home network

A digital rights management (DRM) method and apparatus are provided. The DRM method includes generating a rights object request message for requesting a rights object corresponding to content stored in a media player and transmitting the rights object request message; receiving a rights object response message corresponding to the rights object request message from a media server which receives the rights object request message; and obtaining a rights object using the rights object response message.

Digital rights management method and apparatus

Provided are a method and apparatus for generating a mashup graph. The method includes receiving a set of services and collecting application programmable interfaces (APIs) of the services, and generating a mashup graph by using the collected APIs according to information regarding connections between the APIs and weights between the APIs. Thus, a mashup graph having a simple form in which a user's preference can be reflected can be generated, instead of a complicated connection matrix.

Method and apparatus for generating mashup graph, and method and apparatus for recommending mashup service

Provided are a method and apparatus to ensuring communication security between a control apparatus and a controlled apparatus in a home network. The control apparatus in the home network establishes a registration Secure Authenticated Channel (SAC) with the controlled apparatus by using a Transport Layer Security Pre-Shared Key ciphersuites (TLS-PSK) protocol implemented by using a Product Identification Number (PIN) of the controlled apparatus input from a user, shares a private key with the controlled apparatus via the registration SAC, and uses services of the controlled apparatus via a service SAC established by using the TLS-PSK protocol implemented by using the shared private key to easily implement a framework ensuring communication security in the home network.

Method and apparatus of ensuring security of communication in home network

Provided is a method and apparatus for managing authentication information in a home network, the method includes the operation of receiving Product Identification Number (PIN) information that is externally input and is an identifier allocated to a control device or a controlled device at the time of manufacture; and transmitting authentication information to the control device or the controlled device via a Secure Authenticated Channel (SAC) generated by using a Transport Layer Security Pre-Shared Key ciphersuites (TLS-PSK) protocol implemented by using the PIN information, wherein the authentication information is necessary for a user to control the controlled device via the control device.

Method and apparatus for managing authentication information in home network

An apparatus and method for providing a security service is provided. The apparatus includes a reception module which receives first data including a first public key and marked with a security ID, the first public key being one of a pair of public keys necessary for providing a security service to a home server and the security ID indicating that the first data needs to be encrypted; a response generation module which generates second data by encrypting part of a response message for the first data; and a transmission module which transmits the second data to a home server in a home network.
