Embodiment
Basic thought of the present invention is: when personal network equipment need carry out when mutual with individual's gateway or individual network server; Individual's net gateway or individual network server carry out authentication to the personal network equipment of initiating interactive request, and authentication is carried out through back personal network equipment and individual's net gateway or individual network server alternately.
Below in conjunction with accompanying drawing the enforcement of technical scheme is done further to describe in detail.
A kind of authentication method that personal network equipment is carried out authentication, this method mainly comprises following content:
Personal network equipment carries out alternately with individual's net gateway, and perhaps personal network equipment carries out alternately through individual's gateway and individual network server;
When personal network equipment need carry out when mutual with individual's gateway or individual network server; Individual's net gateway or individual network server need carry out authentication to this personal network equipment of initiating interactive request, and authentication could continue to carry out alternately with individual's net gateway or individual network server through the back personal network equipment.
Further, authentication comprise authentication based on key, based on the authentication of digital certificate.
Mode one: based on the authentication of key.
For personal network equipment is carried out authentication, individual's net gateway or individual network server need be the personal network equipment distributing key.When needs carried out authentication, the key of the personal network equipment that individual's net gateway or individual network server basis calculate was to the personal network equipment authentication.Wherein, this authentication specifically comprises: the key with the personal network equipment that calculates is deciphered the ciphertext of receiving, if decrypted result is consistent with the plaintext comparison of receiving, then authentication is passed through.The ciphertext of receiving be use before for the secret key encryption of personal network equipment distribution.
As shown in Figure 1, individual network server carries out the content that authentication mainly comprises to personal network equipment and is:
A1. people's network server is the personal network equipment distributing key through individual's gateway.
A2. personal network equipment is initiated interactive request through individual's net gateway to individual network server.
A3. people's network server carries out authentication through individual's gateway to personal network equipment.
A4. personal network equipment responds to individual network server return authentication through individual's net gateway.
Here, the generation of key and distribution comprise: individual network server distributes seed for individual's net gateway; The individual nets gateway according to seed, the sign of random number and personal network equipment, and the key of generation personal network equipment, individual's net gateway is that personal network equipment distributes this key and random number corresponding.
Here, seed is generated by individual network server, and random number is that personal network equipment generates by individual's gateway.
Here; When individual network server carried out authentication through individual's gateway to personal network equipment, personal network equipment need send its sign and random number, and the ciphertext of one section plaintext and the corresponding secret key encryption that employing distributed is to individual network server; Individual's network server calculates the key of this personal network equipment according to this sign and random number and seed; And according to this key the ciphertext of receiving is deciphered, if the result after the deciphering is consistent with the plaintext of receiving, authentication success then.
Here, the generation of key can also comprise with distribution: individual network server distributes seed for individual's net gateway; Individual's net gateway generates the key of personal network equipment according to seed and random number, and individual's net gateway is that personal network equipment distributes this key and random number corresponding.
Here, seed is generated by individual network server, and random number is that personal network equipment generates by individual's gateway.
Here; When individual network server carried out authentication through individual's gateway to personal network equipment, personal network equipment need send this random number, and the ciphertext of one section plaintext and the corresponding secret key encryption that employing distributed is to individual network server; Individual's network server calculates the key of this personal network equipment according to this random number and seed; And according to this key the ciphertext of receiving is deciphered, if the result after the deciphering is consistent with the plaintext of receiving, authentication success then.
Here, the generation of key can also comprise with distribution: individual network server is that personal network equipment generates key, and through individual's gateway this key is sent to personal network equipment.
Here; When individual network server carries out authentication through individual's gateway to personal network equipment; Personal network equipment need send the ciphertext of the one section plaintext and the secret key encryption that employing distributed of correspondence to individual network server; Individual's network server is deciphered the ciphertext of receiving according to this key, if the result after the deciphering is consistent with the plaintext of receiving, and authentication success then.
Here it is to be noted: key should be a continuously effective, but does not also get rid of the possibility that adopts other strategies, and for example one-time pad all adopts different keys when promptly mutual at every turn; Perhaps, regular update key etc.
Mode two: based on the authentication of digital certificate.
For personal network equipment is carried out authentication, it is personal network equipment distribute digital certificate with individual's net gateway that the just mechanism of third party needs through individual network server.When needs carry out authentication, individual net gateway or the service of individual's net according to the digital certificate of personal network equipment to the personal network equipment authentication.
Here, the generation of key and distribution comprise: personal network equipment generates private key and PKI; Personal network equipment sends its PKI to the just mechanism of third party through individual's net gateway and individual network server, and the just mechanism of third party returns CA certificate to this personal network equipment.Individual's network server carries out authentication according to the digital certificate of personal network equipment to personal network equipment.
Below to the present invention's elaboration of giving an example.
