Abstract
A method for transmitting content to a user device from a home server in a home network is provided. The method includes: receiving an allocated user public key and a user private key of a user to whom the home server belongs; generating an arbitrary session public key and a session private key, generating an encrypted session private key by encrypting the session private key using a device public key that is a public key of the user device, and transmitting the encrypted session private key to the user device; and transmitting the content encrypted using a predetermined content key and a content key encrypted using the session private key to the user device. According to the method, by binding the content to each user, instead of to each device, the content can be safely and conveniently shared.
