Claim:
A non-transitory computer readable medium for dynamic update of a software-based IPTV conditional access system in a headend connected with a receiver, comprising: a server master key manager managing a master key and encrypting a conditional access code ID by using the master key; a conditional access server manager generating and managing a server list by using a plurality of conditional access servers and a plurality of conditional access server IDs that are inputted, linking and storing an inputted update policy with the conditional access server IDs included in the server list, and controlling execution of the conditional access server on the basis of the stored update policy; and a conditional access code download server requesting the server master key manager to encrypt the plurality of conditional access code IDs that are inputted, generating an ID map of set of conditional access codes by combining the plurality of conditional access codes and the plurality of conditional access code IDs that are encrypted in the server master key manager, and transmitting the ID map of set of conditional access codes and the conditional access codes to the receiver on the basis of the update policy stored in the conditional access server manager.
