摘要： The present invention relates to a method of managing a domain employing a multi-domain manager and a domain system. The method of managing a domain employing a multi-domain manager includes designating a primary domain manager, configuring the domain by registering a domain device with the primary domain manager, designating at least one secondary domain manager of the domain devices, and managing the domain through conjunction of the primary domain manager and the secondary domain manager. Thus, domain management can be performed efficiently by employing a multi-domain manager.

摘要： Disclosed is a method of sharing content. According to the content sharing method, content is received from a service provider using a receive device. A content protection solution supported in a target device is detected. The content is converted so that it is compatible with a content protection solution supported in any one of the target device and the receive device on the basis of the detected content protection solution. The receive device can include a security solution level, indicating a security characteristic of the receive device, in a certificate of the receive device. Accordingly, content transmitted from a service provider using a receive device can be shared efficiently by redistributing the content in such a way as to be compatible with a security solution of a home device.

摘要： A secure signing method, a secure authentication method, and an IPTV system are disclosed. The secure signing method includes preparing digital signature header fields and setting an attribute, calculating a hash digest of content using a hashing algorithm, storing the calculated hash value in a message digest field of the digital signature header, encrypting the message digest using a secret key and inserting the encrypted message digest in a signature field of the digital signature header, and associating the digital signature header with the content by prefixing the digital signature header to the content. The secure authentication method includes checking whether a format and value of a digital signature header of content are appropriate, calculating a hash digest of the content using a hashing algorithm, comparing the calculated hash value with a message digest field of the digital signature header, decrypting the hash value of the signature field of the digital signature header using a public key extracted from a certificate field, and comparing the decrypted hash value with the message digest.
