Fig. 1 shows a scene diagram of a set-top box upgrading and verifying method according to an embodiment of the present invention. As shown, the server 101 and the set-top box 102 are included in the scenario.
In a scenario of an embodiment of the present invention, the server 101 sends a difference upgrade package which is obtained by processing the set-top box upgrade and verification method applied to the server and is directed to the set-top box 102, and the set-top box 102 performs processing of the set-top box upgrade and verification method applied to the set-top box after receiving the difference upgrade package, so as to complete upgrade.
Fig. 2 is a schematic flow chart showing a set-top box upgrading and verifying method applied to a server according to an embodiment of the present invention. As shown, the method comprises:
step S201: generating at least one difference data file according to difference data between at least one first data file in an upgrade package of a current version of a set top box and at least one second data file in an upgrade package of a target version of the set top box;
in an embodiment of the present invention, the information of the current version of a set top box needs to be known in advance according to the current version of the set top box. In an embodiment of the present invention, the information obtaining manner may be obtained by obtaining information of an upgrade package that is sent to the set top box by the server last time, or by sending the current version information while the set top box sends an upgrade request to the server, or by obtaining the information in any other process of performing communication interaction between the set top box and the server. Based on the above idea, those skilled in the art can conceive that any other way that the server can obtain the current version information of the set-top box in advance is within the scope of the present invention.
In an embodiment of the present invention, the generating at least one difference data file according to difference data between at least one first data file in an upgrade package of a current version of a set top box and at least one second data file in an upgrade package of a target version of the set top box includes: acquiring at least one first data file in an upgrade package of a current version of a set top box and at least one second data file in an upgrade package of a target version of the set top box; comparing the difference data between at least one first data file in the upgrade package of the current version of the set top box and at least one second data file in the upgrade package of the target version; and generating at least one difference data file according to the difference data.
In an embodiment of the present invention, the server stores multiple versions of upgrade packages.
In an embodiment of the present invention, the server stores all versions of the upgrade package from the original version to the latest version.
In another embodiment of the present invention, the server may further store therein an upgrade package from a lowest version of all set top boxes communicatively interacting with the server to all versions of the lowest version.
For example, if 1 to N set-top boxes are connected to the server, or the server is only responsible for the upgrade service of 1 to N set-top boxes, the server correspondingly connected to the 1 to N set-top boxes only needs to store the upgrade packages of all versions from the lowest version to the latest version of the 1 to N set-top boxes. If the lowest version of the 1-N set-top boxes is 2017, the server can only reserve the upgrade packages of all versions of the 1-N set-top boxes so far in 2017, so that unnecessary storage space is reduced.
In another embodiment of the present invention, at least one first data file in the upgrade package of the current version of the set-top box and at least one second data file in the upgrade package of the target version of the set-top box may be directly obtained from a re-system upgrade database. Or generating an upgrade data file by compiling the server according to the known version information.
In an embodiment of the present invention, the difference data refers to different data in the upgrade package of the current version and the upgrade package of the target version, that is, difference data in the upgrade packages of the two versions. The comparison may be performed according to one or more combination of data file name, format, memory size, and content to select the difference data to form a difference data file.
For example, if an upgrade package of the current version of a set-top box includes A, B, C three data files, and an upgrade package of the target version or the latest version of the set-top box includes A, B, C, D, E, F six data files, the comparison shows that the D, E, F data files are different, and the difference data file is D, E, F.
In an embodiment of the present invention, the server may store a delta upgrade package between a plurality of different versions.
In an embodiment of the present invention, the server may store a difference data file between any lower version and any higher version.
For example, assuming that the original version is the 2010 version and the latest version is the 2018 version, the server may store a difference data file between the version of any one year in the 2017 year and the version of the 2018 year, or between any one year in the years 2010-2011-2018, or between the year N and the year M as 2010< N < M < 2018.
In another embodiment of the present invention, the server may further store therein a difference data file between a lowest version and a higher version of all set-top boxes communicatively interacting with the server.
For example, if 1 to N set-top boxes are connected to the server, or the server is only responsible for upgrading services of 1 to N set-top boxes, the server correspondingly connected to the 1 to N set-top boxes only needs to store the difference data file between the lowest version and the higher version of the 1 to N set-top boxes, and if the lowest version of the 1 to N set-top boxes is 2013, the server may only reserve the difference data file between the versions in 2013 and 2014 to 2018, so as to reduce unnecessary storage space.
Step S202: carrying out check coding on each difference data file, generating an original check value corresponding to each difference data file, and recording each original check value in an original check value list;
in an embodiment of the present invention, the method for checking the code includes: any one or more of MD5 check coding, parity coding, CRC coding, and BCC XOR coding.
In one embodiment of the present invention, MD5 check coding is preferred. MD5 is called Message Digest Algorithm (english: MD5Message-Digest Algorithm), a widely used cryptographic hash function that can generate a 128-bit (16-byte) hash value to ensure the integrity of the information transmission. MD5 processes incoming information in 512-bit packets, each of which is divided into 16 32-bit sub-packets, and after a series of processing, the output of the algorithm consists of four 32-bit packets, which are concatenated to produce a 128-bit hash value. MD5 is a one-way operation that translates a data string of arbitrary length into a short fixed-length value. Any two strings should not have the same hash value. MD5 checks the correctness of data by performing a hash operation on the received transmission data. The calculated hash value is compared with the hash value transmitted with the data. If the two values are the same, the transmitted data is complete and has not been tampered, so that the use can be assured. MD5 verification may be applied in a number of fields, such as verification of confidential information, verification of downloaded files, encryption of plaintext passwords, etc.
For example, if a file is verified by using the MD5, a file with a verification value is transmitted while the file is transmitted, after the file is locally obtained, the MD5 operation is performed on the file again, and the obtained calculation result is compared with the verification value of the file with the verification value, if the calculation result is consistent with the verification value of the file with the verification value, the transmitted file is considered to have no error, otherwise, the file is considered to have an error.
In an embodiment of the present invention, the check encoding process is capable of generating, for each of the difference data files, a check value including the hash value of the difference data file and a unique check code corresponding to the hash value.
In an embodiment of the invention, verification at different stages or for multiple times can be realized by comparing the verification values, and the safety protection of the differential data file in the whole upgrading process is greatly enhanced.
Step S203: and sending a difference upgrading packet containing the at least one difference data file and the original check value list to the set top box so as to be downloaded and upgraded by the set top box.
In an embodiment of the present invention, the delta upgrade package is compressed and sent to the set top box, so as to reduce an occupied memory during transmission or downloading. Correspondingly, the delta upgrade package is obtained by decompressing after the set top box downloads.
In an embodiment of the present invention, the method further includes: and carrying out check coding on the original check value list to generate an original list check value, and placing the original list check value in the delta upgrade package or independently sending the original list check value to the set top box.
In an embodiment of the present invention, by adding a check code to the original check value list and generating an original list check value, it can be avoided that the original check value list is tampered during transmission or downloading, and a virus or garbage data file corresponding to the tampered list is downloaded.
In an embodiment of the invention, the original list check value may be put into the delta upgrade package together with the at least one difference data file and the original check value list, or may be sent separately.
In an embodiment of the present invention, the original list check value may be sent directly or through a compression method when being sent separately. And if the verification value is sent to the set top box in a compression mode, the set top box needs to decompress the verification value after downloading so as to obtain the original list verification value.
Fig. 3 is a schematic flow chart showing a set-top box upgrading and verifying method applied to a set-top box according to an embodiment of the present invention. As shown, the method comprises:
step S301: downloading a difference upgrading packet sent by the server; the delta upgrade package comprises: generating at least one difference data file according to difference data between at least one first data file in an upgrade package of a current version of the set top box and at least one second data file in an upgrade package of a target version of the set top box, and an original check value list containing corresponding original check values generated corresponding to each difference data file;
in an embodiment of the present invention, the delta upgrade package corresponds to the delta upgrade package formed in the processing manner of the set top box upgrade and verification method applied to the server as shown in fig. 2. The difference data files and the original check value list as described in fig. 2 are obtained by downloading.
In an embodiment of the present invention, if the received delta upgrade packet is sent by a compression method, decompression is required.
In an embodiment of the present invention, after the downloading and decompressing the delta upgrade package sent by the server, and before the performing check coding on each of the delta data files and generating a local check value corresponding to the delta data file, the method further includes: carrying out check coding on an original check value list in the differential upgrade package and generating a local list check value; reading an original list check value in the delta upgrade package, or downloading and reading the original list check value sent by the server; the original list check value is generated corresponding to an original check value list; comparing the local list check value with the original list check value; and under the condition that the list check values are consistent in comparison, performing check coding on each difference data file in the difference upgrading packet and generating a local check value corresponding to each difference data file.
In an embodiment of the invention, if the original list parity can be put into the delta upgrade package together with the at least one difference data file and the original parity list, or sent separately.
In an embodiment of the present invention, if the original list check value is separately transmitted in a compression manner, the set top box needs to decompress after downloading.
For example, the difference data file a sent by the server is packaged with the original check value list L, and the original list check value X1 corresponding to the original check value list L is additionally packaged and sent. After the set-top box receives the two packaged files respectively, reading the difference data file A and the original check value list L respectively, then carrying out check coding on the original check value list L to obtain a corresponding local list check value X2, comparing whether the X2 is consistent with the X1, and if so, continuing the subsequent process. Otherwise, the original check value list L is considered to be in error, and the corresponding difference data file a does not need to be subjected to check coding.
In an embodiment of the present invention, by adding a check code to the original check value list and comparing the check code with the check value of the original list, it can be avoided that the original check value list is tampered during transmission or downloading, and a virus or garbage data file corresponding to the tampered list is downloaded.
Step S302: carrying out check coding on each difference data file, generating a local check value corresponding to each difference data file, and recording each local check value in a local check value list;
in an embodiment of the present invention, each downloaded difference data file is re-check-encoded in the set-top box, and a local check value corresponding to the difference data file is obtained, and a local check value list is further obtained, so that the subsequent comparison and check are performed with the original check value list obtained by downloading.
In an embodiment of the present invention, the check encoding of each difference data file may be implemented by setting a check encoder in the set top box.
In an embodiment of the present invention, the content or manner of the check code is the same as the content or manner of the check code shown in fig. 2, and therefore, the description thereof is omitted here.
Step S303: performing a first comparison between the check value list and the local check value list;
in an embodiment of the present invention, the contents of the first comparison and the second comparison include: a check value number, and a check value item number.
In an embodiment of the present invention, a 128-bit (16-byte) unique check value is generated for each of the difference data files, and the difference data files are compared with the check value values to verify whether they are consistent, so as to prevent the contents of the difference data files from being tampered or lost. In addition, the number of the check value items is compared to ensure that the downloaded data file is not lost, so that the downloaded difference data file can be ensured to be correct.
Step S304: under the condition that the first comparison is consistent, locally upgrading the difference data files corresponding to the original check value or the local check value;
in an embodiment of the present invention, after the difference data file is verified to be consistent, the upgrade may be performed in the set-top box system by a patch method or other upgrade methods.
In an embodiment of the present invention, by comparing the steps, the security of the updated difference data file is greatly increased.
Step S305: checking and coding each upgraded difference data file, generating an upgrade check value corresponding to each upgraded difference data file, and recording each upgrade check value in an upgrade check value list;
in an embodiment of the present invention, the upgrade difference data file may be understood as a difference data file that has been loaded to the set-top box system. Due to the unexpected situations such as packet loss or interruption in the upgrading or loading process, verification is necessary after upgrading is completed to ensure successful downloading.
In an embodiment of the invention, the checking and encoding for the upgraded difference data file is performed when the first comparison is consistent.
Step S306: performing a second comparison on the check value list and the upgrade check value list; under the condition that the second comparison is consistent, prompting that the upgrade is successful;
step S307: if the second comparison is inconsistent, prompting that the upgrade fails;
step S308: and under the condition that the first comparison is inconsistent, prompting that the upgrade fails.
In an embodiment of the present invention, the upgrade process is determined to be successful only when the first comparison and the second comparison are consistent, otherwise, the upgrade process is considered to be failed.
