The inventor finds that with the rapid development of digital television standards, particularly the rapid popularization of UHD (ultra high definition) programs, the safety requirement on a television system is higher, so that the rapid development of CI Plus (Common Interface Plus new universal interface specification) certificates is promoted to generate CIPLus ECP (Common Interface Plus Enhenced Content Protect) certificates.
Because the complexity of the existing CI Plus certificate signature algorithm is low, the existing CI Plus certificate signature algorithm is easy to crack, so that illegal authorized watching of programs to be protected is easy to realize; to strengthen the security of the certificate itself, the CI Plus organization has introduced a second generation CIPlus (CIPlus ECP) certificate, the signature algorithm of which is more complex and more secure. The conditional access module (CAM, condition Access Module) using the original certificate chain is referred to herein as CI Plus CAM, and the CAM supporting the second generation CIPlus certificate is referred to as CIPlus ECP CAM. However, for the same TV system, it is not possible to identify whether CIPlus CAM or CIPlus ECP CAM is inserted, and thus different certificates cannot be selected for authorization authentication.
In order to solve the above problem, in the embodiment of the present application, the television acquires the candidate certificate types supported by itself, and sends the candidate certificate types to the conditional access module, so that the receiving module selects the target certificate type from the reference certificate types supported by itself based on the candidate certificate types; and receiving the target certificate type sent by the condition receiving module, and determining the certificate data corresponding to the target certificate type so as to authenticate the certificate configured by the condition receiving module through the certificate data. The invention determines the target certificate type sent by the condition receiving module according to the candidate certificate type of the television and the reference certificate type of the condition receiving module, so that the television authenticates the certificate configured by the condition receiving module through the certificate data corresponding to the target certificate type, and the condition receiving module is realized.

s100, the television acquires the candidate certificate types supported by the television and sends the candidate certificate types to the conditional access module, so that the receiving module selects a target certificate type from the reference certificate types supported by the television based on the candidate certificate types.
In this embodiment, the tv may include a first generation certificate (CIPlus certificate) and a second generation certificate (CIPlus ECP certificate), or may include only the first generation certificate or the second generation certificate, so the candidate certificate types may be the first generation certificate and the second generation certificate, or may be the first generation certificate or the second generation certificate. In this embodiment, the condition receiving module sends a security authentication request to the television, and after receiving the security authentication request, the television acquires the candidate certificate type supported by the television itself, and then sends the candidate certificate type to the condition receiving module. In practical application, when the condition receiving module starts authorization authentication with the television, the condition receiving module will request to open the content control resource first, then the television will reply to the condition receiving module that the television has opened the content control resource according to the storage state of the current certificate (only the first generation certificate, only the second generation certificate or both certificates are stored), and the condition receiving module informs the candidate certificate type currently supported by the condition receiving module.
Further, in this embodiment, the television acquires the candidate certificate type supported by the television and sends the candidate certificate type to the conditional access module specifically includes:
the television acquires the candidate certificate types supported by the television and sends the candidate certificate types to the conditional access module in the form of binary data.
In particular, the first bit of the binary data represents whether the television supports a first generation certificate and the second bit of the binary data represents whether the television supports a second generation certificate. For example, taking a binary data 11000000 of one byte as an example, the first bit of the binary data is 1, which indicates that the television supports the first generation certificate, and correspondingly, if the first bit of the binary data is 0, it indicates that the television does not support the first generation certificate; further, a second bit of the binary data of 1 indicates that the television supports the second generation certificate, and correspondingly, if the second bit of the binary data is 0, the television does not support the second generation certificate. It can be seen that the embodiments of the present invention can determine the candidate certificate types supported by the television according to the first bit and the second bit of the binary data.
Further, in an implementation manner of the embodiment of the present invention, the selecting process of the target certificate type specifically includes:
if the candidate certificate type comprises a first generation certificate and a second generation certificate, judging whether the reference certificate type comprises the first generation certificate and/or the second generation certificate;
the target certificate type is the second generation certificate if the reference certificate type includes the first generation certificate and the second generation certificate.
Specifically, if the television supports both the first generation certificate and the second generation certificate, it may be determined whether the condition receiving module also supports the first generation certificate and the second generation certificate, and if the condition determining module supports both the first generation certificate and the second generation certificate, the second generation certificate is of the second generation certificate type, that is, the condition determining module performs interactive authentication with the television using the second generation certificate.
Further, if the reference certificate type includes only the first generation certificate, the target certificate type is the first generation certificate;
the target certificate type is the second generation certificate if the reference certificate type includes only the second generation certificate.
Specifically, if the conditional access module is only supporting the first generation certificate, the target certificate type is the first generation certificate. That is, the condition judgment module adopts the first generation certificate to perform interactive authentication with the television; similarly, if the conditional access module only supports the second generation certificate, the target certificate type is the second generation certificate. That is, the condition judgment module adopts the second generation certificate to perform interactive authentication with the television.
Further, in one implementation of the embodiments of the present invention,
further, in an implementation manner of the embodiment of the present invention, the selecting process of the target certificate type specifically includes:
if the candidate certificate type only comprises a first generation certificate, judging whether the reference certificate type comprises the first generation certificate or not;
the target certificate type is the first generation certificate if the reference certificate type includes the first generation certificate.
In this embodiment, if the candidate certificate type is only the first generation certificate, it may be determined whether the condition receiving module supports the first generation certificate, and if the condition receiving module supports the first generation certificate, the target certificate type is the first generation certificate. Thus, the television and conditional access module performs interactive authentication through the first generation certificate. It will be appreciated that if neither the television nor the condition judgment module has a certificate that can be matched, then the following interactive authentication operation will not be performed.
Further, in an implementation manner of the embodiment of the present invention, the selecting process of the target certificate type specifically includes:
if the candidate certificate type only comprises a second generation certificate, judging whether the reference certificate type comprises the second generation certificate or not;
if the reference certificate type includes the second generation certificate, the target certificate type is the second generation certificate.
In this embodiment, if the candidate certificate type is a second generation certificate, it may be determined whether the conditional access module supports the second generation certificate, and if the conditional access module supports the second generation certificate, the target certificate type is the second generation certificate. Thus, the television and conditional access module performs interactive authentication through the second generation certificate. It will be appreciated that if neither the television nor the condition judgment module has a certificate that can be matched, then the following interactive authentication operation will not be performed.
S200, receiving the target certificate type sent by the condition receiving module, and determining certificate data corresponding to the target certificate type so as to authenticate the certificate configured by the condition receiving module through the certificate data.
In this embodiment, after the target certificate type is determined, interactive authentication is performed between the certificate data corresponding to the target certificate type and the certificate configured by the conditional access module.
Further, in an implementation manner of this embodiment, before the television obtains the candidate certificate types supported by the television, the method further includes: when the television is started and initialized, electric energy is sent to the condition receiving module through the power supply module in the television, so that the condition receiving module is electrified and started.
When the television is started and initialized, electric energy is sent to the condition receiving module through the power supply module in the television, so that the condition receiving module is electrified and started.
It can be understood that the condition receiving module obtains electric energy from the power supply module in the television host end, and after the power-on starting, the condition receiving module can obtain the certificate type of the television host end so as to realize the determination and authentication process of the certificate. Next, after the condition receiving module is powered on and started, the condition receiving module may send a security authentication request to a television host, and the television host sends a response message to the condition receiving module after receiving the security authentication request.
Further, when the power supply module in the television host side is powered off, electric energy is obtained from the condition receiving module, that is, when the power supply module in the television host side is powered off, the condition receiving module can be switched into a free power supply module without gaps to supply power to a Flash Memory, so that the condition receiving module is prevented from damaging the Flash Memory due to power failure, the condition receiving module is not required to additionally divide backup sector read data for protection, the Flash storage space is saved, and the Flash Memory utilization rate of the condition receiving module is improved.
