Description

Word stock initialization method, character display method and system and intelligent key equipment
Technical Field
The invention relates to the technical field of electronics, in particular to a word stock initialization method and system, a character display method and system, initialization equipment and intelligent key equipment.
Background
In conventional smart key devices (e.g., USBKEY), characters (including Chinese characters, numbers, letters, symbols, etc.) are represented, exchanged, and processed in the form of internal codes. When the characters need to be displayed, the intelligent secret key equipment converts the internal codes of the characters to be displayed into zone bit codes, extracts the character matrixes of the characters to be displayed from the character library stored in the intelligent secret key equipment by utilizing the zone bit codes, and displays the characters on a screen in a dot matrix mode according to character matrix information. The matrix is the code corresponding to the character displayed on the dot matrix. The graph or the character is stored in a mode of a character die, each point needs one bit to be stored, the bit is 0 to represent that the pixel point is not displayed, and the bit is 1 to represent display. Thus, one byte can store the display condition of 8 pixels. Characters with the size of four in Song body are generally used for display, and one English character just occupies 8 × 16 pixels; whereas a chinese character requires twice, i.e. 16 x 16 pixels to display a chinese character. Thus, storing an english character requires 1 byte of storage per line of 8 dots for a total of 16 lines.
In this case, the smart key device requires a large storage space because all the matrices corresponding to the characters to be displayed need to be stored. The memory of the security chip in a general smart key device cannot meet the requirement of storing such a large word stock, and therefore, a memory extended outside the security chip is mostly used to store the word stock. However, extending a memory external to the security chip to store the word stock increases the cost of the smart key device.

in this embodiment, the MAC value of each character packet is calculated in advance by calculating a MAC (Message Authentication Code) value of each character packet, when calculating the MAC value of each character packet, all the character information in the character packet is combined into a bit sequence, the MAC value of the bit sequence is calculated, the MAC value of each character packet is combined with a key, and the value calculated according to a preset algorithm is used as a check Code to form a check Code library, and the check Code library is stored in the storage module 123 of the smart key device regardless of whether the check Code library is generated by an initialization device or the smart key device itself, and the storage module 123 may be a security chip. The check code library corresponds to each character information packet in the character library.
The third method comprises the following steps: calculating the check code of the character information packet through a hash algorithm according to the secret key;
in this embodiment, the HASH value of each character information packet is calculated in advance through a HASH Algorithm (for example, MD5, Message Digest Algorithm, fifth version of Message Digest Algorithm), when calculating the HASH value of each character information packet, all the character information in the character information packet is combined into a bit sequence, then the HASH value is calculated for the bit sequence, the HASH value of each character information packet is combined with a key to form a check code according to a value calculated by a preset Algorithm, and the check code library is stored in the storage module 123 of the smart key device, where the storage module 123 may be a security chip.

The check code library corresponds to each character information packet in the character library.
In an optional implementation manner in this embodiment, the packetizing module 111 generates one or more character information packets by grouping the character information in the word stock according to a preset policy by at least one of the following manners:
the first method is as follows: setting the number of character information forming one character information packet or the total number of the character information packets, and dividing all the character information in the word stock into one or more character information packets in sequence or at random according to the number of the character information forming one character information packet or the total number of the character information packets;
in the first mode, for example, assuming that the word library has 210 character information, it can be set that each character information packet contains 20 character information on average, and the word library is divided into 11 character information packets, and the last character information packet has 10 character information. Alternatively, the total number of character packets may be set to 10, and then, there are 21 character information per character packet on average. During the division, the character information can be divided into packets in sequence from 1 to 210, each character information packet can be randomly selected and formed, and the packets can be divided into packets in sequence according to strokes of Chinese characters.
The second method comprises the following steps: classifying character information in a word stock according to Chinese characters, numbers, letters, symbols and special characters, and dividing the character information with the same category into a group;
in the second mode, for example, the word stock may be divided into 5 character information packets, where one character information packet includes character information corresponding to chinese characters, one character information packet includes character information corresponding to numeric characters, one character information packet includes character information corresponding to english alphabetic characters, one character information packet includes character information corresponding to symbols, and the last character information packet includes character information corresponding to special characters. In addition, if the Chinese characters are divided into simplified and traditional Chinese characters, the Chinese characters can be further divided into 6 character information packets, the character information corresponding to the simplified Chinese characters is divided into one character information packet, and the character information corresponding to the traditional Chinese characters is divided into another character information packet.
The third method comprises the following steps: dividing character information corresponding to characters of which the simultaneous use frequency is higher than a preset threshold into a group according to industry habits;
in the third mode, for example, in the financial industry application, the frequency of displaying the combination of the two characters of the "gold" character and the "amount" character is very high (higher than the use of a preset threshold value, for example, the probability of the two characters of the "gold" and the "amount" appearing at the same time is greater than 40%), and when the character information in the word stock is packaged, the character information corresponding to the two kanji characters can be divided into one character information package. Similarly, there are "account", "number", "confirmation", etc., which are only illustrated here, and the embodiment is not limited specifically.
In actual transaction application, the intelligent key device sends the identification of the character information (the 'gold' word and the 'amount' word) to be displayed to the terminal. When finding that the character information (the golden character and the quota character) is in the same character information packet, the terminal only issues the character information packet to the intelligent key device, after receiving the character information packet, the intelligent key device verifies the received character information packet by using the locally stored key, and if the verification is passed, the terminal selects the character information of the golden character and the quota character to be displayed from the character information packet, and then the character information can be displayed according to the character information. By applying the sub-packaging mode under the strategy, the terminal only needs to send a character information packet, the transmission data volume is small, and the intelligent key equipment only needs to check one check code after receiving the character information packet, so that the operation can be completed, and the efficiency is higher. Specifically, the terminal may be a PC, a mobile terminal such as a mobile phone, or a remote background, the intelligent key device communicates with the terminal during a transaction, and each character information packet in the installed word stock may be downloaded in advance on the terminal.
The method is as follows: all Chinese characters in a character library are divided into a plurality of character roots, and character information corresponding to the character roots with the combination frequency higher than a combination preset threshold value is divided into a group.
In the fourth mode, for example, all the Chinese characters can be divided into a plurality of radicals (e.g. a plurality of radicals, or a plurality of parts). The radicals with higher combination frequency (higher than the combination preset threshold value, for example, the combination frequency is greater than 40%) are combined in one character information packet, so that the individual character information in one character information packet can form a plurality of combinations to display a plurality of Chinese characters. For example, the Chinese characters ' Zhi ' Qing ' and ' Zheng ' are combined in a character information packet, so that the character information packet only occupies 1.5 Chinese characters, but can meet the display requirements of ' clear ' and ' quiet ' of 2 Chinese characters, thereby further saving space and improving efficiency. By the method, under the condition of meeting the display requirements of the same number of Chinese characters, the data volume of the character information packet can be greatly reduced.
In this embodiment, the initialization device performs packet combination on all the character information in the word stock, and the intelligent optimized combination mode provided by this embodiment can improve the efficiency of extracting the word stock by the intelligent key device, and at the same time, reduce the data amount transmitted between the terminal and the intelligent key device, and improve the transmission speed. Of course, the present embodiment excludes other ways of grouping and combining the character information in the word stock, and this is only an example.

In this embodiment, the key stored locally in the smart key device and the check code library calculated according to the key may be generated by each smart key device itself, or may be generated by the initialization device and sent to each smart key device.

In practical application, the smart key device needs to display characters "turn", "account", "gold" and "amount", the smart key device extracts the check code of the character information packet (possibly one character information packet or a plurality of character information packets) containing the character information corresponding to the characters "turn", "account", "gold" and "amount" from a pre-stored check code library, under normal conditions, one or more character information packets issued by the terminal should include the character information corresponding to the characters "turn", "account", "gold" and "amount", the smart key device calculates the check code according to the character information packet issued by the terminal, compares the calculated check code of the character information packet with the check code of the extracted character information packet, and displays the characters "turn", "account", "gold" and "amount" if the comparison result is consistent; otherwise, the terminal is modified when issuing the character information "forward", "account", "gold" and "amount", for example, modified to "receive", "benefit", "gold" and "amount", the check code is calculated according to the character information packet issued by the terminal, and when comparing the calculated check code of the character information packet with the extracted check code of the character information packet, the comparison result is inconsistent, so that the smart key device does not display or report an error, for example, display "error", or voice alarm, etc. By the verification method, the terminal can be prevented from being tampered under the condition of issuing the character information, and the safety is improved.

According to the character display system provided by the embodiment of the invention, the intelligent key equipment verifies the received character information packet through the locally stored check code, and the character to be displayed is displayed after the verification is passed, so that the character information data imported from the outside is ensured to be accurate and legal, and the character to be displayed is correctly displayed.

Example 4
The present embodiment provides a font library initialization method applied to the font library initialization system 10 in embodiment 1.
Fig. 6 is a flowchart of a method for initializing a word stock according to this embodiment, and as shown in fig. 6, the method includes the following steps:
s601, the initialization equipment generates one or more character information packets according to the character information in the word stock in a grouping mode according to a preset strategy, wherein the character information packets comprise at least two pieces of character information;
in an optional implementation manner of this embodiment, the character may include: chinese characters (complex form, simplified form, etc.), numbers, letters, symbols, special characters, etc. The character information includes: the characters correspond to a type matrix and codes, and each character can be identified by the codes.
In an optional implementation manner of this embodiment, grouping the character information in the word stock according to a preset policy to generate one or more character information packets includes at least one of the following manners:
the first method is as follows: setting the number of character information forming one character information packet or the total number of the character information packets, and dividing all the character information in the word stock into one or more character information packets in sequence or at random according to the number of the character information forming one character information packet or the total number of the character information packets;
in the first mode, for example, assuming that the word library has 210 character information, it can be set that each character information packet contains 20 character information on average, and the word library is divided into 11 character information packets, and the last character information packet has 10 character information. Alternatively, the total number of character packets may be set to 10, and then, there are 21 character information per character packet on average. During the division, the character information can be divided into packets in sequence from 1 to 210, each character information packet can be randomly selected and formed, and the packets can be divided into packets in sequence according to strokes of Chinese characters.
The second method comprises the following steps: classifying character information in a word stock according to Chinese characters, numbers, letters, symbols and special characters, and dividing the character information with the same category into a group;
in the second mode, for example, the word stock may be divided into 5 character information packets, where one character information packet includes character information corresponding to chinese characters, one character information packet includes character information corresponding to numeric characters, one character information packet includes character information corresponding to english alphabetic characters, one character information packet includes character information corresponding to symbols, and the last character information packet includes character information corresponding to special characters. In addition, if the Chinese characters are divided into simplified and traditional Chinese characters, the Chinese characters can be further divided into 6 character information packets, the character information corresponding to the simplified Chinese characters is divided into one character information packet, and the character information corresponding to the traditional Chinese characters is divided into another character information packet.
The third method comprises the following steps: dividing character information corresponding to characters of which the simultaneous use frequency is higher than a preset threshold into a group according to industry habits;
in the third mode, for example, in the financial industry application, the frequency of displaying the combination of the two characters of the "gold" character and the "amount" character is very high (higher than the use of a preset threshold value, for example, the probability of the two characters of the "gold" and the "amount" appearing at the same time is greater than 40%), and when the character information in the word stock is packaged, the character information corresponding to the two kanji characters can be divided into one character information package. Similarly, there are "account", "number", "confirmation", etc., which are only illustrated here, and the embodiment is not limited specifically.
In actual transaction application, the intelligent key device sends the identification of the character information (the 'gold' word and the 'amount' word) to be displayed to the terminal. When finding that the character information (the golden character and the quota character) is in the same character information packet, the terminal only issues the character information packet to the intelligent key device, after receiving the character information packet, the intelligent key device verifies the received character information packet by using the locally stored key, and if the verification is passed, the terminal selects the character information of the golden character and the quota character to be displayed from the character information packet, and then the character information can be displayed according to the character information. By applying the sub-packaging mode under the strategy, the terminal only needs to send a character information packet, the transmission data volume is small, and the intelligent key equipment only needs to check one check code after receiving the character information packet, so that the operation can be completed, and the efficiency is higher. Specifically, the terminal may be a PC, a mobile terminal such as a mobile phone, or a remote background, the intelligent key device communicates with the terminal during a transaction, and each character information packet in the installed word stock may be downloaded in advance on the terminal.
The method is as follows: all Chinese characters in a character library are divided into a plurality of character roots, and character information corresponding to the character roots with the combination frequency higher than a combination preset threshold value is divided into a group.
In the fourth mode, for example, all the Chinese characters can be divided into a plurality of radicals (e.g. a plurality of radicals, or a plurality of parts). The radicals with higher combination frequency (higher than the combination preset threshold value, for example, the combination frequency is greater than 40%) are combined in one character information packet, so that the individual character information in one character information packet can form a plurality of combinations to display a plurality of Chinese characters. For example, the Chinese characters ' Zhi ' Qing ' and ' Zheng ' are combined in a character information packet, so that the character information packet only occupies 1.5 Chinese characters, but can meet the display requirements of ' clear ' and ' quiet ' of 2 Chinese characters, thereby further saving space and improving efficiency. By the method, under the condition of meeting the display requirements of the same number of Chinese characters, the data volume of the character information packet can be greatly reduced.
S602, the initialization equipment acquires a key, calculates a check code corresponding to each character information packet of the word stock according to the key, and sends the key and the corresponding check code to intelligent key equipment;
in an optional implementation manner of this embodiment, the key includes a same key or multiple different keys, and the smart key device includes at least two keys; the keys received by the various smart key devices may be the same key or different keys. In this alternative embodiment, multiple smart key devices may share a single key or may use different keys.
In this embodiment, specifically, the initialization device may further form a check code library with the generated check codes, where the check code library corresponds to each character information packet in the word library.
S603, the intelligent key device receives and stores the key and the check code corresponding to each character information packet in the word stock.
In the library initialization method provided in FIG. 6, a key and a checksum are computationally generated by an external device (initialization device) of the smart key device, and the smart key device locally stores the key and checksum.
Fig. 7 is a flowchart of another word stock initialization method provided in this embodiment, and as shown in fig. 7, the method includes the following steps:
s701, the initialization equipment generates one or more character information packets for the character information in the word stock according to a preset strategy group, wherein the character information packets comprise at least two character information;
s701 is the same as step S601, and is not described herein again.

In the method of library initialization provided in FIG. 7, the verification code library is generated by the smart key device itself, and the external device (initialization device 11) merely provides the library.
