In a preferred embodiment, when the first public key is different from the second public key, the second smart terminal does not perform a decryption operation.

An automatic authorization method based on the smart terminal in this embodiment is implemented based on at least one first smart terminal and one second smart terminal. The first smart terminal stores a first public key, and the second smart terminal stores a second public key and a private key. The second public key and private key are a set of matching key pairs. Public Key and Private Key are a pair of keys obtained by an algorithm (ie, a public key and a private key). The public key is the public part of the key pair, and the private key is not. The public part. Public keys are typically used to encrypt session keys, verify digital signatures, or encrypt data that can be decrypted with the corresponding private key. The key pair obtained by this algorithm is guaranteed to be unique worldwide. When using this key pair, if one piece of data is used to encrypt a piece of data, it must be decrypted with another key. For example, encrypting data with a public key must be decrypted with a private key. If it is encrypted with a private key, it must be decrypted with a public key, otherwise the decryption will not succeed. Based on the characteristics of the public key and the private key, the automatic authorization method in this embodiment is mainly implemented based on the feature. After the first smart terminal and the second smart terminal establish a connection through the USB data line connection or the plug-in connection, the second smart terminal performs operation control on the first smart terminal to obtain the authorization of the first smart terminal, to the first intelligent terminal. An access request is sent, and the first smart terminal sends an encrypted authorization information to the second smart terminal according to the access request. The first intelligent terminal encrypts the authorization information by using a public key encryption algorithm. Common public key encryption algorithms include: RSA, ElGamal, backpack algorithm, Rabin (Rabin's encryption method can be said to be a special case of RSA method), Diffie-Hellman (DH) key exchange protocol public key encryption algorithm, Flliptic Curve Cryptography (ECC, elliptic curve encryption algorithm). Currently, the most widely used RSA algorithm (acronym by the inventors Rivest, Shmir, and Adleman) is a well-known public key encryption algorithm. When the first wisdom After the terminal can encrypt the authorization information by using the public key encryption algorithm, the terminal further sends the encrypted authorization information to the second intelligent terminal. At this time, after receiving the encrypted authorization information, the second intelligent terminal first calls its internal second public key for verification, and verifies whether the first public key of the encrypted authorization information matches its private key. If it matches, the second smart terminal invokes its private key decryption algorithm to decrypt the authorization information by using the private key. If there is no match, the second intelligent terminal does not decrypt the encrypted authorization information to further ensure the security of the private key and prevent it from being stolen by others. When it is determined that the first public key and the second public key are the same public key, the second smart terminal further invokes its private key decryption algorithm to decrypt the authorization information to finally obtain the authorization information, thereby obtaining the first intelligence. Authorization of the terminal. Based on the unique matching feature of the public key and the private key, the second intelligent terminal can decrypt the authorization information encrypted by using the public key by using a private key decryption algorithm, and automatically obtain the authorization information sent by the first intelligent terminal.

Currently, the most widely used RSA algorithm (acronym by the inventors Rivest, Shmir, and Adleman) is a well-known public key encryption algorithm. After the first smart terminal encrypts the authorization information by using the public key encryption algorithm, the encrypted authorization information is further sent to the second smart terminal. At this time, after receiving the encrypted authorization information, the second intelligent terminal first calls its internal second public key for verification, and verifies whether the first public key of the encrypted authorization information matches its private key. If it matches, the second smart terminal invokes its private key decryption algorithm to decrypt the authorization information by using the private key. If there is no match, the second intelligent terminal does not decrypt the encrypted authorization information to further ensure the security of the private key and is not stolen by others. When it is determined that the first public key and the second public key are the same public key, the second smart terminal further invokes its private key decryption algorithm to decrypt the authorization information to finally obtain the authorization information, thereby obtaining the first intelligence. Authorization of the terminal.
