Description
Technical field
The present invention relates to the restorative procedure that condition receives IC-card in (Condition Access) system, is the restorative procedure to the IC-card corrupted data concretely.
Background technology
Present DTV generally all adopts the condition of DTV to receive functions such as (CA) system carries out protecting data encryption, the operation of charging.The functional module that the condition receiving system of DTV mainly comprises has:
Service management unit: realize to management of information such as user profile, user equipment information, consumer premise information, authorized user message, financial information.
Programme information unit: realize management, comprise channel, date and time arrangement, program CA information etc. to the broadcast items table.
Scrambling/descrambling unit: realize to being transmitted scrambling descrambling, change or the control of business code flow characteristic.
Encryption/decryption element: the enciphering/deciphering of realizing ECM (Entitlement Control Message) and EMM (Entitlement Management Message) is handled, and decryption oprerations separates with receiver usually, such as in smart card, carrying out.
The deciphering module of condition receiving system in user's terminal equipment generally all is to adopt IC-card to carry out identification, stored value card, critical data deciphering etc. at present, so IC-card has been born very important part work in the whole condition receiving system.Can IC-card operate as normal, is the prerequisite that can digital television system operate as normal.IC-card generally is to be inserted in the DTV STB, reads and writes use by STB.
The software of IC-card is generally formed by IC-card COS system (Chip Operating System) and based on the file structure of COS system.The file system of IC-card COS system is three layers a physical structure, forms a hierarchical structure that is similar to DOS by master control file (MF, Master File), proprietary file (DF, Dedicated File) and constituent instruments (EF, Elementary File):
1. the master control file is the root of whole file system.Every card has and has only a master control file, and it at first is established in the personalization process of card, and in the life cycle of card, exist always and remain valid, but the public information of storage card and be various application services.Comprise information such as document control parameter and file security attribute through the individualized master control file of setting up.
2. proprietary file is the file of under the master control file, setting up to different application, is a kind of file structure that contains constituent instruments that is positioned under the master control file, the total data and the secure data relevant with application operating of its certain application of storage.Proprietary file is set up by founding file command, and the foundation operation of proprietary file is controlled by the security attribute of master control file.Under proprietary file, generally no longer set up sub-proprietary file, only set up constituent instruments.The corresponding a kind of application of DF.
3. constituent instruments have been stored the data and the management information of various application, and it is present under master control file and the proprietary file.Constituent instruments are divided into two types from memory contents: safe constituent instruments (SEF, Secret Elementary File) and work constituent instruments (WEF, Working Elementary File).
Safe constituent instruments comprise be used for User Recognition with encrypt relevant private data (PIN, PIN) etc., its content does not allow to be read, but can and write with special instruction modification.Below master control file and each proprietary file, safe constituent instruments can only be arranged, KEY in the file and the type of PIN can be specified with the modification authority.
The work constituent instruments comprise the real data of application, and its size and number receive the restriction in master control file and space that proprietary file has.The space of whole file system is assigned with when master control file, proprietary file and constituent instruments are created and confirms, is physically no longer changing.Visit certain constituent instruments, must select corresponding master control file and proprietary file earlier.
Data on the IC-card promptly are meant the file in the IC-card COS system.In case the file system on the IC-card is destroyed, a then whole IC-card shows as damage and can't use.
Generally all more than 100,000 times, according to normal use, the life-span generally can arrive 10 years to the read-write number of times of IC-card at present.In actual user's use, because problems such as user's the random hot plug to IC-card, read-write spread of voltage, STB electromagnetic compatibility all can cause IC-card to occur damaging.Under some extreme case, if IC-card just in the write data process, power down suddenly also can cause IC-card to damage.Therefore, damaging often appears in IC-card.
The damage of IC-card generally is divided into physical damage and corrupted data.For the IC-card of physical damage, then can't re-use.But for the IC-card of corrupted data, the mode that then can pass through again write-in program and data is with the IC-card reparation that damages.According to statistics, the IC-card major part of damage is caused by corrupted data that all physical damage only accounts for a very little part.
For the IC-card that damages, generally be the user when televiewing, after reminding IC-card to damage or can not find IC-card through TV, IC-card is delivered to the operator place by the user, give the user more change card by operator.And after operator is accumulated to some with IC-card, worse IC-card sent to condition receiving system (CAS) manufacturer and repair or change.CAS manufacturer then analyzes IC-card, chooses the part of physical damage, returns to operator after the IC-card reparation with corrupted data.Whole process more complicated, and the cycle is long, and user, operator and CAS manufacturer are all brought many troubles and pressure.
According to statistics, at the beginning of 2011, national IC-card accumulative total issued volume has surpassed 1.1 hundred million, and a year issued volume maintains about 20,000,000 basically at present.
The reparation of IC-card at present generally is that the bad card to reclaiming that adopts is write a program again, does not provide operator to pass through the function that network is directly repaired.
Summary of the invention
