摘要： Disclosed is a method of controlling time-related constraints in a memory card with a security function. The method of the present invention of controlling time-related constraints in a memory card with a Rights Object(RO) manager includes a step of forming a channel with the RO manager in order to play back contents, by a host application; b) a step of reading an RO status through the channel and recognizing a time-related RO status, by the host application; c) a step of checking a content use authorization by the RO manager upon request for playback of the contents by the host application; d) a step of decrypting and sending the contents to the host ap¬ plication, if the contents use authorization is valid; and e) a step of sending a count decrease message to the RO manager, by the host application, to decrease a count if a predetermined time lapses, according to the time-related information.

摘要： A method of generating a pre-subscription Conditional Access System (CAS) chip is disclosed. In order for a mobile terminal to receive a conditional-access broadcasting service, a broadcasting service subscription process has been performed on the CAS chip in advance. A CAS Initial Delivery (CID) key is generated using a seed key and an algorithm, stored in an issuance Personalization Secure Application Module (PerSAM) card, and the generated CID key is registered in the CAS chip. A subscriber key is generated using a seed key and an algorithm, stored in a subscription PerSAM card. The generated subscriber key is inserted into a subscription Entitlement Management Message (EMM). A pre-subscription CAS chip is generated by registering the subscription EMM in the CAS chip in which the CID key is registered.
