Description
Technical field
The restorative procedure that the present invention relates to IC-card in condition reception (Condition Access) system is the restorative procedure to IC-card corrupted data concretely.
Background technology
Current Digital Television generally all adopts condition reception (CA) system of Digital Television to carry out the functions such as protecting data encryption, charge operation.The functional module that the condition receiving system of Digital Television mainly comprises has:
Service management unit: realize the management to information such as user profile, user equipment information, user's predetermined information, authorized user message, financial information.
Programme information unit: realize the management to broadcast items table, comprise channel, date and arrangement of time, program CA information etc.
Scrambling/descrambling unit: realize being transmitted scrambling descrambling, change or the control of business code flow feature.
Encryption/decryption element: realize ECM(Entitlement Control Message) and EMM(Entitlement Management Message) enciphering/deciphering process, decryption oprerations is separated with receiver conventionally, such as carrying out in smart card.
The deciphering module of condition receiving system in user's terminal equipment, is all generally 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 whole condition receiving system.Can IC-card normally work, and is the prerequisite that can digital television system normally work.IC-card is to be generally inserted in digital TV set-top box, by Set Top Box, reads and writes use.
The software of IC-card is generally comprised of IC-card COS system (Chip Operating System) and the file structure based on COS system.The file system of IC-card COS system is the physical structure of three layers, by master control file (MF, Master File), proprietary file (DF, Dedicated File) and constituent instruments (EF, Elementary File), forms a hierarchical structure that is similar to DOS:
1. master control file is the root of whole file system.Every card has and only has a master control file, and first it be established in the personalization process of card, exists always and remains valid, public information that can storage card be various application services in the life cycle of card.By the individualized master control file of setting up, comprise the information such as document control parameter and file security attribute.
2. proprietary file is the file of setting up for different application under master control file, is a kind of file structure that contains constituent instruments being positioned under master control file, and it stores total data and the secure data relevant to application operating of certain application.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.A corresponding a kind of application of DF.
3. constituent instruments have been stored data and the management information of various application, and it is present under master control file and proprietary file.Constituent instruments are divided into two classes from storage content: safe constituent instruments (SEF, Secret Elementary File) and work constituent instruments (WEF, Working Elementary File).
Safe constituent instruments comprise for user identification with encrypt relevant private data (PIN, PIN) etc., its content does not allow to be read out, but can and write with special instruction modification.Below master control file and each proprietary file, can only have safe constituent instruments, the KEY in file and the type of PIN and modification authority can be specified.
The real data that work constituent instruments comprise application, its size and number are subject to the restriction in master control file and space that proprietary file has.The space of whole file system is assigned with and determines when master control file, proprietary file and constituent instruments create, and no longer changes physically.Access certain constituent instruments, must first select corresponding master control file and proprietary file.
Data on IC-card refer to the file in IC-card COS system.Once the file system on IC-card is destroyed, whole IC-card shows as damage and cannot use.
The read-write number of times of IC-card is at present generally all more than 100,000 times, and according to normal use, the life-span generally can arrive 10 years.In actual user's use procedure, due to user to problems such as the random hot plug of IC-card, read-write spread of voltage, Set Top Box electromagnetic compatibilities, all can cause IC-card to occur damaging.Under some extreme case, if IC-card is being write in data procedures, power down suddenly, also can cause IC-card to damage.Therefore, damaging often appears in IC-card.
The damage of IC-card is generally divided into physical damage and corrupted data.For the IC-card of physical damage, cannot re-use.But for the IC-card of corrupted data, can the IC-card of damage be repaired by the mode of write-in program and data again.According to statistics, the IC-card major part of damage all causes by corrupted data, and physical damage only accounts for a very little part.
For the IC-card damaging, be generally user when televiewing, by TV, remind IC-card damage or can not find after IC-card, by user, IC-card is delivered to operator and locates, by operator to user's change card more.And operator is accumulated to IC-card after some, then send to condition receiving system (CAS) manufacturer to repair or change bad IC-card.CAS manufacturer analyzes IC-card, chooses the part of physical damage, and the IC-card of corrupted data is repaired to Hou Fangei operator.Whole process more complicated, and the cycle is long, and user, operator and CAS manufacturer are all brought to 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 20,000,000 left and right substantially at present.
The reparation of IC-card is at present generally that the bad card to reclaiming adopting is write a program again, does not provide operator to pass through the function that network is directly repaired.
Summary of the invention
For above problem, the invention provides the restorative procedure of IC-card in a kind of condition receiving system, when IC-card corrupted data, by simple and quick mode, IC is repaired, guaranteed the normal of system, and the maintenance efficiency that improves IC-card, has shortened repairing efficiency greatly, has saved maintenance cost.
The restorative procedure of IC-card in condition receiving system of the present invention, comprising:
