Abstract
A security system, method and device for use in a network for providing a real-time stream are provided. A server updates security association of a terminal device by periodically providing a key stream. When the key stream for changing the security association of the terminal device is received from the server, the terminal device updates stored key stream information after identifying at least one changed field in the key stream and performs a security policy with the server using the updated key stream information. When a security setting operation is performed through a stream notification periodically provided from the server, an unnecessary waste of system resources can be reduced by updating only a specific changed field through the stream notification and reducing the load of generating a security association table.
