Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart of an identity information generating method according to an embodiment of the present invention, including:
110: the first network equipment acquires first information, wherein the first information comprises user identity characteristic information.
The first information is identification information containing user characteristics including biological characteristics such as fingerprint, iris and voiceprint, and the first information includes data obtained by electronizing the biological characteristics. The user characteristics also include hardware characteristics corresponding to the user, such as a serial number of the user's handset and/or a string of random numbers generated by a device belonging to the user. The input of the user identity characteristic information can use special input equipment, such as fingerprint input equipment and iris input equipment, or a keyboard can be arranged on the first network equipment so that a user can input numbers and/or characters, or the special input equipment can be integrated on the first network equipment for inputting user information such as fingerprints and irises, and the invention does not limit the input equipment of the user information.
120: the first network device obtains second information, the second information being used for obfuscating the encryption.
The second message may be a random string of characters sent by the server, or a string of characters preset by the user and/or manufacturer.
130: the first network device combines the first information with the second information to generate first identity information.
The combination of the first information and the second information includes, but is not limited to, directly combining the first information and the second information, or confusing and combining the first information and the second information according to a certain algorithm. For example, in the embodiment of the present invention, the first information is a string of 128-bit strings, the second information is another string of 56-bit strings, and the two strings are directly combined to generate a 184-bit string as the first identity information, i.e., the first 128 bits of the first identity information are the first information, and the second 56 bits of the first identity information are the second information. In another embodiment of the present invention, the first message is a 100-bit number string, and the second message is another 100-bit number string, which are combined into the identity information by the following algorithm: all the digits of the first information correspond to odd digits as identity information in sequence, and all the digits of the second information correspond to even digits as the first identity information in sequence, so that a 200-digit string is generated as the first identity information.
The first identity information generated by confusion not only maintains the one-to-one correspondence relationship between the first information and the user, but also cannot directly obtain the characteristic information of the user from the first identity information.
140: the first network device uses the first identity information for data encryption and/or authentication.
When the first network device encrypts data using the first identity information, the first identity information may be used as a password to encrypt the data, or a key may be generated according to the first identity information to encrypt the data, for example, in an embodiment of the present invention, the first identity information is a 32-byte numeric string. When the first network device needs to encrypt the data, the data is encrypted by using the number string as a key of Advanced Encryption Standard (AES).
When the first network device performs authentication using the first identity information, the authentication information sent by the other device may be compared with the first identity information, and if the two are the same, the authentication of the first network device with respect to the other device is successful.
The identity information is generated through the steps, so that the user can use the identity characteristic information of the user to encrypt and/or verify the identity of the user, the identity characteristic information cannot be leaked, and the safety of the data and the communication process is improved.
According to the embodiment of the invention, the combination method of the first information and the second information includes splicing combination, so that the first network device obtains the first identity information by using less computing resources.
According to the embodiment of the invention, the first information comprises the user biological characteristic information and/or the hardware characteristic information, so that the user can conveniently input the first information.
According to the embodiment of the invention, the first equipment comprises the personal mobile equipment and/or the network camera equipment, so that data on the network camera equipment and/or the personal mobile equipment is safer.
According to the embodiment of the invention, the second information is sent by the server, so that the second information can be used as a dynamic password, and the security of the user equipment and the data is further improved.
In an embodiment of the present invention, a first network device using first identity information for data encryption and/or authentication includes: the first network equipment receives second identity information, and the second identity information is generated and sent by the second network equipment; the first network equipment compares the second identity information with the first identity information; and if the first identity information is the same as the second identity information, the first network equipment successfully authenticates the second network equipment.
By comparing the first identity information, the first network equipment can confirm whether the second network equipment is used by the same user, and the communication safety between the first network equipment and the second network equipment is ensured.
For example, in the embodiment of the present invention, the identity information in the second network device is composed of a digital string sent by the server after the fingerprint of the user is digitized. The first network device sends the generated identity information to the second network device for identity confirmation, if the identity information in the first network device is the same as the identity information of the second network device, which means that the user of the first network device is the same as the user of the second network device, the second network device successfully authenticates the identity of the first network device, and can perform the next communication.
One embodiment of the present invention further comprises: the first network equipment receives a second secret key, wherein the second secret key is used for decrypting information encrypted by the first secret key, and the second identity information is encrypted through the first secret key; the first network device decrypts the second identity information using the second key.
Since the identity information includes the characteristic information of the user, the first network device encrypts the identity information in order to prevent the identity information from being acquired by other network devices. For example, in the embodiment of the present invention, the server generates a pair of keys capable of performing asymmetric encryption, the server sends one of the keys to the first network device, and the first network device receives the key and encrypts the identity information using the key. The server sends another key to the device to be decrypted for decrypting the identity information. In another embodiment of the present invention, the server sends a string of characters to the first network device, and the first network device symmetrically encrypts the identity information and uses the characters sent by the server as an encrypted password. And the server sends the same character string to the equipment needing to decrypt the identity information, and the equipment is used for decrypting the information encrypted by the first network equipment.
In an embodiment of the present invention, the data encryption and/or authentication performed by the first network device using the first identity information includes: the first network device generates a third key according to the first identity information, and the third key is used for encrypting data of the first network device.
The identity information contains unique characteristic information of the user, and the user can encrypt the storage data and/or the communication data by using the identity information, so that the encrypted information can be decrypted only by the user himself. For example, in the embodiment of the present invention, the user uses the identity information itself as a key in the AES encryption algorithm to symmetrically encrypt the information stored on the first network device. In another embodiment of the present invention, the first network device extracts feature information of the identity information using a hash algorithm, and encrypts the data of the user using the feature information as a key.
