[0048] Example 1

[0049] This embodiment provides a method for encrypting and decrypting resources of a Cocos game package, such as Figure 1~Figure 3 As shown, the following steps are included:

[0050] S100, the step of obtaining resources to be encrypted, specifically includes:

[0051] S110, obtaining the game package packaging process; in this embodiment, considering that the game package needs to be encrypted after packaging, it is necessary to monitor the game package packaging process;

[0052] S120, setting the process completion benchmark, resource type and resource conversion format; in this embodiment, considering that the important resources in the game package and the resources that are difficult to encrypt are picture resources, it is necessary to encrypt the picture resources, so the resource type is picture class; the process completion benchmark is that Cocos packages the game resources to a completed state; when encrypting picture resources, only binary data can be processed, and the picture is composed of pixel point data and color value data, so starting from this, the resource conversion format is designed to be binary format;

[0053] S130, obtaining a Cocos game package based on the packaging process and the process completion benchmark;

[0054] Specifically, the process information of the packaging process is identified, and the process information is compared with the process completion benchmark; when the process information matches the process completion benchmark, it means that Cocos has completed the packaging of the game and has generated a corresponding game package, so the storage address of the game package is obtained, and the storage address is the packaging destination corresponding to the game packaged by Cocos, including but not limited to the text information of the storage path; the storage address is accessed, and the data packet matching the process information in the storage address is extracted, and the data packet is the game packaged by Cocos; in this step S100, the main purpose is to complete the initialization configuration operation and the related game package acquisition operation, and provide a data basis for subsequent encryption operations. At the same time, the corresponding game package is obtained through the form of process verification, which ensures the integrity of the data. At the same time, during the process monitoring process, dangerous users are prevented from interfering with or intruding the packaging process, which improves security to a certain extent;

[0055] Correspondingly, part of the implementation code of step S130 is as follows:

[0056] callForEach(GetAllBuildTextures(buildResults), (uuid, next) => {

[0057] var file = buildResults.getNativeAssetPath(uuid);

[0058] if(file.substr(-3) === 'png') { / / Image ending with png

[0059] EncryptOnePng(file, next, next);

[0060] } else {

[0061] next();

[0062] }

[0063] }, () => {

[0064] _log('encrypt Pngs Finish');

[0065] callback && callback();

[0066] });

[0067] S140, traversing the game resources in the Cocos game package based on the resource type to obtain a first resource to be encrypted;

[0068] Specifically, several attribute information respectively corresponding to several game resources in the Cocos game package are identified; the attribute information includes but is not limited to the resource type, resource storage format, resource occupancy value, resource ID information, etc. of the game resource; a screening algorithm is used to screen out the first attribute information matching the resource type from the several attribute information; in this embodiment, the screening algorithm uses a regular matching algorithm to further improve the efficiency of screening and the operability of the method; the game resource corresponding to the first attribute information is set as the first resource to be encrypted; the first resource to be encrypted is the resource that is difficult to encrypt in the original Cocos game package, and in this embodiment, it is a picture resource;

[0069] S150, performing a resource format conversion operation on the first resource to be encrypted based on the resource conversion format to obtain a second resource array to be encrypted; Step S150 is a connecting step. On the one hand, the format of the resource to be encrypted is converted, which not only unifies the resource format for unified calling or processing, but also solves the problem that the image resource is difficult to encrypt, and provides a data basis for subsequent encryption operations;

[0070] Specifically, the resource format conversion operation includes: converting the first resource to be encrypted into resource data whose data format matches the resource conversion format to obtain the third resource data to be encrypted; the third resource data to be encrypted is the image resource data in binary format, and the data must be read in binary format during subsequent encryption, reading and calling; setting a first storage threshold; in this embodiment, the first storage threshold is 1 byte; identifying the storage occupancy value of the third resource data to be encrypted; the storage occupancy value is the size of the third resource data to be encrypted, such as 100 bytes; calculating the quotient of the storage occupancy value and the first storage threshold to obtain a resource array reference value; because the subsequent encryption operation mainly adopts the offset encryption algorithm, it is necessary to convert the resource into an array form for separate storage to facilitate subsequent encryption operations; the resource array reference value represents how many resource array containers need to be configured; therefore, the resource array container is configured based on the first storage threshold and the resource array reference value to obtain a resource array container with a resource array reference value size of the first storage threshold; importing the third resource data to be encrypted into the resource array container to obtain the second resource array to be encrypted; in this embodiment, the second resource array to be encrypted is an array of 1 byte;

[0071] Correspondingly, part of the implementation code of step S150 is as follows:

[0072] function EncryptOnePng(file, cbk, fail) {

[0073] / / _log('Compressing: ' + file)

[0074] / / if(file.indexOf('resources / native / 0c / 0c') != -1)

[0075] {

[0076] fs.readFile(file,'binary',function(err,data)

[0077] {

[0078] if(err)

[0079] _log(err);

[0080] else

[0081] S200, game resource encryption and decryption steps, specifically including:

[0082] S210, configure the offset encryption algorithm, encryption key, decryption key and risk list; in this embodiment, the encryption key and decryption key are set according to the specific encryption requirements, the encryption key and decryption key are in the form of character strings, and are related to each other; the risk list is based on the high-risk access users or bad access users or blacklist access users in the game resources downloaded or obtained from the network data security center, and is used to provide corresponding user verification during the decryption operation, and further control the call security of the encrypted game package;

[0083] S220, performing an offset iterative encryption operation on the second array of resources to be encrypted based on the offset encryption algorithm, the encryption key, and the decryption key to obtain an encrypted game resource package;

[0084] Specifically, the offset iterative encryption operation includes: configuring a first empty array and a first empty data packet; the first empty array and the first empty data packet are both empty format containers for data to be stored; setting a string conversion format; the string conversion format is an array-to-string format, and the string format is the same as the format of the binary resource data before being converted into an array form; integrating the second resource array to be encrypted, the encryption key and the decryption key into the first empty array to obtain a third array to be encrypted; in this embodiment, not only the game resource data is iteratively offset, but also the encryption key and the decryption key are iteratively offset, thereby further improving security; When the decryption key is integrated into the first empty array, the encryption key and the decryption key are also converted into the form of long arrays respectively; the offset encryption algorithm is called to perform offset processing on the third array to be encrypted to obtain a fourth offset array; the fourth offset array is converted into an encrypted string according to the string conversion format; the encrypted string is imported into the first empty data packet to obtain a fourth encrypted data packet; when the data is offset processed, the data itself is changed, which does not affect the location and occupancy of the data. After the offset processing, the data is observed again in the form of garbled code, which is extremely safe and not easy to be cracked, so the fourth encrypted data packet is the encrypted game resource package;

[0085] Specifically, the offset encryption algorithm includes the following processing logic for the offset of the third array to be encrypted:

[0086] A data offset formula and a key offset formula are set; a first data reference offset value, a first encryption reference offset value and a first decryption reference offset value are set based on the encryption key and the decryption key; specifically, the first data reference offset value includes: an array first offset value, an array last offset value, a logical encryption value and a golden constant; correspondingly, the data content of the first encryption reference offset value and the first decryption reference offset value is the same as the data content of the first data reference offset value, and both include a first related value, a last related value, a logically related encryption value and a golden constant; correspondingly, in this embodiment, the data offset formula and the key offset formula are set according to specific circumstances; the formulas are all mathematical formulas used for iterative adjustment of the first data reference offset value, the first encryption reference offset value and the first decryption reference offset value during subsequent step loop iterations, including but not limited to mathematical formulas and value ranges;

[0087] Correspondingly, the main offset iteration principle is: identifying the first data in the second to-be-encrypted resource array, setting the first data as the reference offset data; identifying the first encryption character in the encryption key, identifying the first decryption character in the decryption key, setting the first encryption character and the first decryption character as the reference encryption character and the reference decryption character respectively; performing the offset step on the reference offset data, the reference encryption character and the reference decryption character based on the first data reference offset value, the first encryption reference offset value and the first decryption reference offset value;

[0088] The offset step includes: performing offset processing on the benchmark offset data based on the first data benchmark offset value to obtain first offset data; performing offset processing on the benchmark encrypted character based on the first encryption benchmark offset value to obtain a first encrypted offset character; performing offset processing on the benchmark decrypted character based on the first decryption benchmark offset value to obtain a first decrypted offset character; performing an offset value iteration step based on the first offset data, the first encrypted offset character and the first decrypted offset character; correspondingly, the specific principle of the offset processing takes the benchmark offset data as an example: right-shifting the benchmark offset data in the original data structure by the same number of bits as the last offset value of the array, which is two bits in this embodiment, and complementing the first bit of the right-shifted data with The value of the first offset value of the array is the same. In this embodiment, the first offset value of the array is 0, so 0 is added on the left; the data finally obtained after the offset plus the position is bound with the logical encryption value to obtain the final first offset data; the processing process of the first encrypted offset character and the first decrypted offset character is the same as the above principle; correspondingly, the resource data after the offset processing is already in garbled form, and the difficulty of cracking is extremely high. At the same time, the logical encryption value added in the offset processing will further increase the difficulty of decryption. When decrypting, the same logical value must be entered for matching before decryption can be successful, which makes the resources in the originally complex garbled form more secure; correspondingly, after executing the above steps once, the obtained results, i.e., the first offset data, the first The encrypted offset character and the first decrypted offset character are substituted into the data offset formula and the key offset formula to obtain new reference offset data, and then the unencrypted data in the array is offset processed according to the reference offset data. In this iterative process, the encryption key data of each step will change according to the result of the offset processing in the previous step, which is extremely difficult to crack. In this embodiment, the data offset formula and the key offset formula are set according to the golden constant, and the result of each iteration can be increased by the golden constant, thereby achieving the change of each reference offset data, which is extremely safe; finally, after the loop iteration is completed until all the data in the array are offset processed, the encryption operation is terminated; therefore, the offset value iteration step includes: substituting the first offset data into the data The first encryption offset character is substituted into the key offset formula to obtain a second encryption offset value; the first decryption offset character is substituted into the key offset formula to obtain a second decryption offset value; the new offset data of the second resource array to be encrypted is identified, the new base encryption character of the encryption key is identified, and the new base decryption character of the decryption key is identified; based on the second data base offset value, the second encryption base offset value, the second decryption base offset value, the new base offset data, the new base encryption character and the new base decryption character, the offset step is returned; through this step, a high-security encryption operation of the data is performed, which makes up for the shortcomings of the prior art;

[0089] Correspondingly, part of the implementation code of step S220 is as follows:

[0090] function xxtea_encrypt(str, key) {

[0091] if (str == "") {

[0092] return "";

[0093] }

[0094] / / Convert the passed in image string to be offset into a long array;

[0095] var v = str2long(str, true);

[0096] / / Convert the passed secret key into a long array;

[0097] var k = str2long(key, false);

[0098] var n = v.length - 1;

[0099] / / z is the last value of the array, y is the first value of the array, and delta is a fixed golden constant;

[0100] var z = v[n], y = v[0], delta = 0x9E3779B9;

[0101] / / Define the initialization value, q is the number of loop iterations;

[0102] var mx, e, q = Math.floor(6 + 52 / (n + 1)), sum = 0;

[0103] / / Loop through each round of encryption;

[0104] while (q-- > 0) {

[0105] / / Each time add the result of the previous round to the golden constant;

[0106] sum = sum + delta;

[0107] / / Shift the obtained value right by 2 bits, fill the left side with 0, and perform bitwise AND logic on the result and 3;

[0108] e = sum >>> 2 & 3;

[0109] S230, detecting the calling state of the encrypted game resource package, configuring a decryption algorithm based on the offset iterative encryption operation, and performing a resource decryption operation based on the risk list, the calling state and the decryption algorithm;

[0110] Specifically, this step takes into account the application of a specific game package. Although it is encrypted, it cannot prevent normal users from calling it. Therefore, when the calling state is that there is a first user calling the encrypted game resource package, the first user needs to run the game, so the resource decryption operation is performed;

[0111] The resource decryption operation includes: obtaining the first user information of the first user, and determining whether there is second user information matching the first user information in the risk list; if so, it means that the first user is an illegal user and there is a risk of misappropriation of game resources, so the misappropriation of the game resource package is blocked from the source, so the encrypted game resource package is deleted, and an alarm operation is performed, and the alarm operation is to send a message to the management background of the game resource package, such as the mobile terminal of the administrator, or to make a voice prompt call; if not, it means that the user is a normal user, so the decryption algorithm is called to decrypt the encrypted game resource package; specifically, in this embodiment, the decryption algorithm is an operation algorithm configured according to a processing logic opposite to the offset iterative encryption operation, and the decryption algorithm is used specifically for decrypting the game resource package encrypted by this method; considering security, the decryption algorithm and the game resource package are not configured in the same data file.
