It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
As shown in fig. 1, a first embodiment of the present invention provides an intelligent lock, which includes a receiving module and a processing module.
In the embodiment of the invention, the receiving module is used for receiving the input registration password, for example, when a user needs to set an unlocking password of the intelligent lock, the registration password can be input and received by the receiving module. Optionally, the receiving module may be a mechanical key, a screen with a touch screen function, or may be a communication unit, and may receive a registration password sent by a terminal of a user owner, which is not limited specifically.
As shown in fig. 1, in the embodiment of the present invention, the processing module includes a storage unit and a processor, and in other embodiments, the storage unit may be located in the processor, that is, the storage unit may be a word unit of the processor, and is not limited specifically.
As shown in fig. 1, in the embodiment of the present invention, a storage unit stores a key, all contents or part of contents of the key may be set in advance in a smart lock generation process and stored in the storage unit, or part of contents of the key may be set by a user and stored in the storage unit. For example, the secret key includes an identification code of the processor and a custom password, and when the smart lock is produced, the developer may use the identification code of the processor and the custom word set by the developer as the custom password to form the secret key, for example, the developer may include but is not limited to determining the custom word according to the property of the lock, the company name, the random setting, and the like, and the custom may include numbers or english letters; or the developer may store the id as part of the key in the storage unit, and the owner may set another part of the key as needed and form the key with the id of the processor. In the embodiment of the invention, the identity identification code of the processor is used as a part of the secret key, so that each intelligent lock has a corresponding unique secret key, and the subsequent encryption process is safer.
Optionally, the processor may be composed of any one or more processor chips including an MCU singlechip, an FPGA, a CPLD, a DSP, an ARM, and the like. In an embodiment of the present invention, the processor is configured to perform bit padding on the registered password to obtain a password inclusion body, and perform encryption processing on the password inclusion body through an encryption algorithm according to the key to obtain a password ciphertext and store the password ciphertext, for example, in the storage unit or in the processor.
As shown in fig. 2, a second embodiment of the present invention provides a storage method, which can be applied to the above-mentioned smart lock, including steps S100-S300:
s100, receiving a registration password.
Alternatively, the user may input the registration password through a mechanical key, a screen with a touch screen function, or the user may input the registration password on a terminal in communication with the smart lock, and the registration password is received by the receiving module of the smart lock.
S200, carrying out bit complementing processing on the registered password to obtain a password inclusion body.
In the embodiment of the invention, the password inclusion body is a password obtained by adding other characters or symbols in front of and behind the registered password or adding other characters or symbols in front of and behind the registered password for bit complementing processing, so that the security of the password can be improved.
Specifically, step S200 includes one of steps S210, S220, and S230:
s210, adding first content with a first preset digit before the first digit of the password is registered to obtain a password inclusion body.
Optionally, the first predetermined number of digits may be adjusted as needed, and the first content may be any text, for example, the registered password is 123456, and the first predetermined number of digits is 6, where the first content may be 888999, so as to obtain the password inclusion 888999123456.
S220, adding second content with a second preset digit after the last digit of the password is registered to obtain a password inclusion body.
Similarly, the second predetermined number of digits can be adjusted as needed, and the second content can be any character, for example, the registered password is 123456, the first predetermined number of digits is 6, and the first content can be 666444, so that the password containing body is 1234566444.
And S230, adding a third content with a third preset digit before the first digit of the registered password and adding a fourth content with a fourth preset digit after the last digit of the registered password to obtain a password inclusion body.
Similarly, the third predetermined number of digits and the fourth predetermined number of digits may be adjusted as needed, and the third content and the fourth content may be any characters, for example, the registered password is 123456, the third predetermined number of digits is 3, the first content may be 444, the fourth predetermined number of digits is 3, the first content may be 122, and thus the password inclusion body 444123456122 is obtained.
S300, encrypting the password inclusion body through an encryption algorithm according to the secret key to obtain a password ciphertext and storing the password ciphertext.
Specifically, the processor reads the secret key in the storage unit, encrypts the password inclusion body by using the secret key and an encryption algorithm, thereby encrypting the password inclusion body into a password ciphertext, and stores the password ciphertext in the processor or the storage unit in the processing module for practical verification during subsequent unlocking. It should be noted that the encryption algorithm includes, but is not limited to, AES128, DES, 3DES, MD5, sha1, sha256, and the like, and is not limited in particular.
For example, taking AES128 as an example, the length of the cipher inclusion body after the bit padding processing is 16 bytes, the processor id with the key being eight bytes + the custom cipher with eight bytes, that is, the length of the key is also 16 bytes, and after the cipher inclusion body is encrypted by using the key in combination with AES128, a cipher text with 16 bytes can be obtained.
As shown in fig. 1, a third embodiment of the present invention provides another intelligent lock, which includes a receiving module and a processing module. It should be noted that the receiving module and the processing module of the smart lock of the third embodiment have the same structure as the smart lock of the first embodiment. The receiving module of the third embodiment may be configured to receive an unlocking password in addition to the function of the first embodiment, the storage unit in the processing module of the third embodiment stores a secret key and a password ciphertext stored by the storage method of the second embodiment, and the processor in the processing module may be configured to decrypt the password ciphertext by a decryption algorithm according to the secret key in addition to the function of the first embodiment to obtain a password inclusion body, and perform comparison processing according to the unlocking password and a registered password of the password inclusion body to obtain a comparison processing result. It should be noted that, when the comparison processing results are the same, the representation of successful unlocking verification can unlock the intelligent lock, and when the comparison processing results are different, the representation of unsuccessful unlocking verification does not unlock the intelligent lock.
As shown in fig. 3, a fourth embodiment of the present invention provides a decryption method, which can be applied to the smart lock of the third embodiment, including steps S400-S600:
s400, receiving an unlocking password.
Alternatively, the input object (e.g., the householder or other person) may input the unlocking password through a mechanical key, a screen with a touch screen function, or a terminal in communication with the smart lock, and the unlocking password is received by the receiving module of the smart lock. It should be noted that the unlocking password may be a registration password or may be a dummy password containing the registration password.
S500, the cipher ciphertext is decrypted through a decryption algorithm according to the secret key, and a cipher inclusion body is obtained.
Specifically, the decryption algorithm corresponds to the encryption algorithm, for example, the encryption algorithm used is an AES128 algorithm, the decryption algorithm is also the AES128 algorithm, the processor acquires all cipher texts from the storage unit, then decrypts the cipher texts by using the key through the decryption algorithm, and at this time, the plaintext of the cipher inclusion body is obtained and stored in the cache of the processor. It is understood that the password inclusion body includes a registration password for registration performed by the subscriber.
S600, comparing the unlocking password with the registration password of the password inclusion body to obtain a comparison processing result.
And when the comparison processing results are the same, the characteristic unlocking verification is successful, and when the comparison processing results are different, the characteristic unlocking verification is failed. In the embodiment of the invention, the registered password of the intelligent lock is encrypted by AES128 and then stored in the storage unit, after the input object inputs the unlocking password, the encrypted password ciphertext is read out from the storage unit and decrypted into the plaintext of the password inclusion body when the comparison processing is needed, the comparison between the unlocking password and the registered password in the password inclusion body is carried out to determine whether the comparison processing results are the same or different, the safety of the registered password can be well protected, when the intelligent lock is violently damaged and the storage unit is taken out, the data read out from the storage unit is the encrypted password ciphertext which is a messy code, which algorithm cannot be used for encryption, and the encryption algorithm cannot be read. In the other step, even if the encryption algorithm is known as AES128, the secret key cannot be known, and the cipher text cannot be decrypted, so that the security of the registered cipher is improved.
In the embodiment of the present invention, S600 includes steps S610 to S620:
s610, password content with preset digits at the front position is determined from the unlocking password.
Alternatively, in order to improve security and prevent peeping, when the input object inputs the unlocking password, in addition to directly inputting the same content as the registration password, a meaningless other number may be added before and/or after the registration password, so that the content in the input unlocking password needs to be compared one or more times for such a case. It should be noted that the preset number of bits is the number of bits of the registered password, and the registered password is exemplarily 123456 and 6 bits, where the preset number of bits is 6 bits, and it is assumed that the unlock password is 88812345699, and the content of the password in the first 6 bits is 888123.
S620, comparing the password content with the registered password, obtaining the same comparison processing result when the comparison result is the same, removing the first digit in the unlocking password to obtain a new unlocking password when the comparison result is different, and returning to the step of determining the password content with the preset digit at the front position from the unlocking password according to the new unlocking password until the comparison result is the same or until the total digit of the new unlocking password is smaller than the preset digit, and determining that the comparison processing result is different.
Specifically, the processor compares the password content with the registered password contained in the password containing body by calling a comparison function, and when the comparison result is the same, the obtained comparison processing result is the same, at the moment, the unlocking verification is successful, and the intelligent lock is unlocked. It should be noted that, when a plurality of password inclusion bodies are stored in the storage unit, the password content and the registered password in each password inclusion body are compared one by one during the comparison. Taking the example in step S610 as an example, the 888123 and the registered password 123456 are compared, the comparison result is different, the first digit in the unlocking password is removed to obtain a new unlocking password, that is, the new unlocking password is 8812345699, and the password content with the front position preset digit is determined from the unlocking password according to the new unlocking password, that is, the password content with the front 6 digits is determined as 881234 again, the 881234 and the registered password 123456 are compared, the comparison result is also different, the first digit in the unlocking password is removed again to obtain a new unlocking password, that is, the new unlocking password is 812345699, the password content with the front 6 digits is continuously determined again until the password content with the front 6 digits is 123456 and is consistent with the registered password 123456, the comparison result is obtained to be the same, or the comparison processing result is determined to be different until the total digit of the new unlocking password is smaller than the preset digit. For example, the unlocking password is 88812346959, when the first bit in the unlocking password is removed to obtain a new unlocking password of 46959 when the comparison is continuously performed and the password content of the first 6 bits is determined, only 5 bits of 46959 are smaller than 6 bits at this time, the comparison results cannot be the same, and therefore it is determined that the comparison processing results are different, and the intelligent lock is not unlocked.
Optionally, the processing module may further include a speaker, and after it is determined that the comparison processing result is different, the prompt content may be played through the speaker or displayed in the screen when the receiving module is the screen, so as to prompt that the password is wrong and the password needs to be re-input.
Optionally, the decryption method according to the embodiment of the present invention may further include step S700, where S700 is located before S600:
s700, determining the total digit of the unlocking password;
when the total digits of the unlocking passwords are larger than or equal to the preset digits, the password content with the preset digits at the front position is determined from the unlocking passwords;
or,
and when the total digit of the unlocking password is less than the preset digit, determining that the comparison processing results are different.
Optionally, the preset digit is a digit of the registration password, for example, if the registration password is 123456, the preset digit is 6 digits, the processor determines a total digit of the unlock password input by the input object, and if the total digit of the unlock password is greater than or equal to the preset digit, then step S610 is executed. And when the total digit of the unlocking password is less than the preset digit, the unlocking password does not have the possibility of being the same as the registration password, so that the comparison processing result is directly determined to be different, and the intelligent lock is not unlocked.
