Because the private key is only possessed by a legal server, the video color ring and the identity information capable of uniquely identifying the equipment are signed by adopting the private key, so that the video color ring information is ensured not to be stolen or tampered in the transmission process, the problem that the color ring address is stolen is avoided, the rights and interests of a video color ring provider are guaranteed, and the safety of personal information and personal property of a user is enhanced; meanwhile, the receiver can play the video color ring on the basis of confirming that the playing address of the video color ring is real and effective, the authenticity of the video color ring played by the receiver is ensured, the video color ring is prevented from being forged by a third party, the problem that the color ring address is stolen is avoided, the rights and interests of a video color ring provider are guaranteed, and the problems of confidentiality, integrity and resistance to denial of the existing video color ring in the transmission process are also solved.
In addition, before the first signature information, the video color ring back tone information and the identity information are sent to the receiver, the video color ring back tone information and the identity information are encrypted by the first symmetric key, the public key of the receiver is used for encrypting the first symmetric key, the first signature information, the encrypted video color ring back tone information, the encrypted identity information and the encrypted first symmetric key are sent to the receiver, the receiver decrypts the encrypted first symmetric key by the private key of the receiver, and the encrypted video color ring back tone information and the encrypted identity information are decrypted by the decrypted first symmetric key.

In addition, the specific steps of signing the video color ring information and the identity information of the server by using the private key of the server comprise: and calculating the hash values of the video color ring information and the identity information of the server, and signing the hash values by using a private key of the server. Because the video color ring back tone information and the identity information original text of the server are large, if the original text is directly encrypted, the time consumption is long, the efficiency is low, and the hash value of the original text is much smaller than the original text in terms of data volume, so that the hash value is encrypted, the safety of the information in the transmission process of the video color ring back tone from the server to the receiver is ensured, and the encryption efficiency is further improved. Moreover, the data length of the hash value is determined by the hash algorithm and is not influenced by the original text data volume, so that the encryption efficiency can be effectively ensured by encrypting the hash value.
In addition, the video color ring is pre-stored in the server in the following way, which specifically comprises: and receiving second signature information, video color ring information and identity information of a producer sent by the video color ring producer, wherein the second signature information is signature information obtained by signing the video color ring and the identity information of the producer by a private key of the producer.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.
The first embodiment of the invention relates to a transmission method of video color ring back tone, which can be applied to a video color ring back tone server. In the embodiment, the video color ring back tone information and the identity information of the server are signed by a private key of the server to obtain first signature information; and sending the first signature information, the video color ring back tone information and the identity information to a receiver, so that the receiver can verify the first signature information according to the received video color ring back tone information, the identity information and the public key of the server, and play the video color ring back tone indicated by the video color ring back tone information after the verification is passed.
In the embodiment, because the private key is only possessed by a legal server, the private key is adopted to sign the polyphonic ringtone and the identity information capable of uniquely identifying the equipment, so that the video polyphonic ringtone information is ensured not to be stolen or tampered in the transmission process, and the problem that the polyphonic ringtone address is stolen is avoided; meanwhile, the receiver can verify the signature information, the received video color ring information and the server identity information through the public key when receiving the information, so that the authenticity of the video color ring played by the receiver is ensured, the video color ring is prevented from being forged by a third party, the problem that a color ring address is stolen is avoided, and the problems of confidentiality, integrity and resistance to denial of the existing video color ring in the transmission process are solved.
The following describes implementation details of the transmission method of the video color ring in this embodiment in detail, and the following is only provided for easy understanding and is not necessary to implement the present solution.
A flow chart of the transmission method of the video polyphonic ringtone in this embodiment is shown in fig. 1, and includes:
in step S101, the video color ring server receives a call request of a calling device, and obtains video color ring information to be transmitted.
Specifically, the calling device initiates a call service, and combines device information, session information, and call service information into text information, which is carried in a call request and sent to the network side. The call service information may specifically include information such as a mobile phone number of the calling device, a mobile phone number of the called party, and additional information. After receiving a call request of calling equipment, the video color ring server obtains a called party mobile phone number through analysis of the call request, and then obtains video color ring information to be transmitted according to the called party mobile phone number. In a specific implementation example, the video color ring server may query whether a video color ring identification number corresponding to the called party mobile phone number exists according to the called party mobile phone number, and if the corresponding video color ring identification number does not exist, a failure result is fed back; and if the corresponding video color ring back tone identification number exists, obtaining the video color ring back tone information to be transmitted, specifically, obtaining a playing address of the video color ring back tone to be transmitted.
In step S102, the video color ring back tone server signs the video color ring back tone information and the identity information of the video color ring back tone server with a private key of the server to obtain first signature information. It can be understood that the public key is called a public key, only the key known by the device is called a private key, the public key and the private key form a pair of asymmetric keys together, and the decryption can be completed only through the corresponding public key through the information encrypted by the private key, so that the information encrypted by the private key can be understood as signing. In this step, the video color ring server signs the video color ring information and the identity information of the video color ring server by using the private key of the server, wherein the identity information of the server may specifically be device information of the server, and the video color ring information may specifically be a playing address of the video color ring. In another specific example, the video color ring information, the identity information of the server, the additional information and the session information may also be signed by using a private key of the server, so as to obtain the first signature information.
Step S103, the video color ring back tone server encrypts the video color ring back tone information and the identity information of the video color ring back tone server by using the first symmetric key, and encrypts the first symmetric key by using the public key of the receiver.
Specifically, the 6-bit encryption key may be generated by the encryptor, and the video polyphonic ringtone information and the identity information may be encrypted by using the encryption key generated by the encryptor. In order to ensure that the receiver and only the receiver can complete the decryption operation on the video color ring information and the identity information, the public key of the receiver is also required to be used for encrypting the encryption key generated by the encryption machine in the step. Because the encryption efficiency of the symmetric key is higher than that of the asymmetric key, the symmetric key is used for encrypting the video color ring back tone information and the identity information of the video color ring back tone server, and the public key of the receiver is used for encrypting the first symmetric key, so that the receiver can decrypt the symmetric key, the plaintext transmission of the original text of the video color ring back tone information and the identity information is avoided, and the encryption can be completed in less time.
And step S104, the video color ring server sends the first signature information, the encrypted video color ring information, the server identity information and the encrypted first symmetric key to a receiver. The receiving party in this embodiment may be a calling device or a called party, and is not limited herein.
And step S105, the receiver verifies the first signature information according to the received video color ring information, the identity information of the video color ring server and the public key of the server.
Specifically, after receiving video color ring back tone information encrypted by a first symmetric key, identity information of a video color ring back tone server, first signature information and the first symmetric key encrypted by a public key of the receiver, the receiver decrypts the encrypted first symmetric key by using a private key of the receiver, decrypts the received encrypted video color ring back tone information and the server identity information by using the decrypted first symmetric key, decrypts the first signature information by using the public key of the server to restore signed information, compares the restored signed information with the video color ring back tone information decrypted by using the first symmetric key and the server identity information, and if the comparison result is consistent, determines that the verification is passed.
And step S106, after the verification is passed, the receiver plays the video color ring indicated by the received video color ring information.
In the embodiment, the encrypted transmission process of the video color ring information from the server to the receiver ensures that the video color ring information is not easy to be stolen and tampered in the transmission process, avoids the problem that the color ring address is stolen, and ensures the rights and interests of users, thereby ensuring three elements of information safety:
(1) confidentiality: the current video color ring playing address adopts encrypted transmission, so that the stealing of the video color ring playing address is avoided;
(2) integrity: the current video color ring playing address has integrity checking capability, and is prevented from being maliciously tampered by a third party;
(3) resistance to denial: the playing address generated by the video color ring server has a verification mechanism of the anti-repudiation property and cannot be forged by a third party.
In addition, in a specific implementation, the video polyphonic ringtone can be stored in the video polyphonic ringtone server through the process shown in fig. 2. The following is a detailed description of the process shown in fig. 2:
in step S201, the video color ring server receives production data sent by a producer of the video color ring. Specifically, the production data comprises second signature information, video color ring and identity information of a producer; the second signature information is obtained by signing the video color ring and the identity information of the producer by using the private key of the producer.
Step S202, the video color ring server verifies the second signature information according to the video color ring, the identity information of the producer and the public key of the producer.
Specifically, the video color ring server decrypts the second signature information by using the public key of the producer, restores the information signed by the private key of the producer, compares the restored signed information with the received video color ring and the identity information of the producer, and judges that the verification is passed if the comparison result is consistent.
And after the verification is passed, the step S203 is entered, and the video color ring is stored in the video color ring server.
In a specific implementation, the video color ring and the identity information of the producer can be ciphertexts encrypted by the second symmetric key, so that the video color ring and the identity information of the producer can be transmitted by the ciphertexts. That is, the production data includes the second signature information, the video polyphonic ringtone encrypted by the second symmetric key, and the identity information of the producer, and the second symmetric key can be sent to the video polyphonic ringtone server after being encrypted by the public key of the video polyphonic ringtone server.
When the video color ring server verifies the second signature information, the second symmetric key can be decrypted by using the private key, then the ciphertext encrypted by the second symmetric key is decrypted by using the second symmetric key, the video color ring and the identity information of the producer are obtained, and whether the verification is passed or not is judged by comparing whether the restored signed information and the video color ring obtained after decryption by using the second symmetric key are consistent with the identity information of the producer or not. By the encrypted transmission of the video color ring information from the video producer to the server, the video color ring information is ensured not to be stolen or falsified easily in the transmission process, the problem that the color ring address is stolen is avoided, the rights and interests of a video color ring provider are guaranteed, meanwhile, the encryption mode is improved, and the confidentiality coefficient is improved.
The second embodiment of the invention relates to a method for transmitting video color ring. The second embodiment is further improved from the first embodiment.
Specifically, in the first embodiment of the present invention, the video color ring server directly signs the video color ring information and the server identity information to obtain the first signature information. In the second embodiment of the present invention, the video color ring server calculates the hash value of the video color ring information and the identity information of the server, and then signs the hash value with the server private key to obtain the first signature information. The problem of low encryption efficiency caused by overlarge original text (video color ring back tone information and identity information of the server) is solved, the encryption efficiency is improved, and in addition, the video color ring back tone server also needs to verify the identity of the calling equipment. The specific flow is shown in fig. 3.
In step S301, the video color ring server receives a call request of the calling device.
Specifically, the calling device initiates a call service, and merges device information, session information, and call service information into text information, which is carried in a call request and sent to the network side, where the call service information may specifically include information such as a mobile phone number of the calling device, a mobile phone number of a called party, and additional information. In addition, in order to enable the video color ring server to verify the identity of the calling device, in this embodiment, the call request further includes third signature information, where the third signature information is signature information obtained by signing the identity information, the session information, and the call service information of the calling device with a private key of the calling device.
It should be noted that, in a specific implementation, the calling device may further encrypt the identity information, the session information, and the call service information of the calling device by using a third symmetric key, and encrypt the third symmetric key by using the public key of the server and send the encrypted third symmetric key to the server. The method not only ensures that the server can decrypt to obtain the symmetric key and avoids the plaintext transmission of the identity information, the session information and the calling service information original text of the calling equipment, but also adopts the symmetric key for encryption and has high encryption efficiency.
It should be noted that, in another specific implementation, the third signature information may also be signature information obtained by signing a hash value of the identity information, the session information, and the call service information of the calling device with a private key of the calling device, and since the data length of the hash value is determined by a hash algorithm and is not affected by the original data volume, the problem of too low encryption efficiency due to too large identity information, session information, and call service information of the calling device can be avoided, and the encryption efficiency is improved.
In step S302, the video color ring server verifies the third signature information, and obtains the video color ring information to be transmitted after the verification is passed.
Specifically, the video color ring server verifies the third signature information according to the identity information, the session information and the call service information of the calling device and the public key of the calling device. And when the verification information is consistent, the video color ring server acquires the video color ring information to be transmitted.
In a specific implementation, if the identity information, the session information and the call service information of the calling device received by the video polyphonic ringtone server are the information encrypted by the third symmetric key, the third symmetric key is obtained by decrypting with the private key of the video polyphonic ringtone server, and the identity information, the session information and the call service information of the calling device are obtained by decrypting with the third symmetric key.
In another specific implementation, if the third signature information is signature information obtained by signing the hash values of the identity information, the session information, and the call service information of the calling device with the private key of the calling device, when the third signature information is verified, whether the verification is passed is determined by comparing whether the restored signed information is consistent with the hash values of the identity information, the session information, and the call service information of the calling device.
The video color ring server ensures the legality of the calling equipment through the verification of the third signature information, avoids the problem that the color ring address is mistakenly transmitted to a third party due to the fact that the session is illegally distributed, and improves the anti-theft capability of the color ring address.
In step S303, the video color ring server calculates a hash value of the video color ring information and the identity information of the video color ring server, and signs the hash value with a private key of the video color ring server to obtain first signature information.
In step S304, the video color ring server encrypts the video color ring information and the identity information of the video color ring server with the first symmetric key, and encrypts the first symmetric key with the public key of the receiver. This step is similar to step S103 and will not be described herein again.
In step S305, the video color ring server sends the first signature information, the encrypted video color ring information, the server identity information, and the encrypted first symmetric key to the receiving party. This step is similar to step S104 and will not be described herein again.
In step S306, the receiving party verifies the first signature information according to the received video polyphonic ringtone information, the identity information of the video polyphonic ringtone server, and the public key of the server.
Specifically, after receiving video color ring back tone information encrypted by a first symmetric key, identity information of a video color ring back tone server, first signature information and the first symmetric key encrypted by a public key of the receiver, the receiver decrypts the encrypted first symmetric key by using a private key of the receiver, decrypts the received encrypted video color ring back tone information and the identity information of the server by using the decrypted first symmetric key, and performs hash value calculation on the decrypted video color ring back tone information and the identity information of the server. And then, decrypting the first signature information by using the public key of the server to restore the signed information, comparing the restored signed information with the locally calculated hash value, if the comparison result is consistent, judging that the verification is passed, and entering the step S307.
In step S307, after the verification is passed, the receiving party plays the video color ring indicated by the received video color ring information.
According to the embodiment, the hash value of the original text is calculated firstly, and then the hash value is encrypted, so that the safety of information in the transmission process is ensured, and the encryption efficiency is improved.

Specifically, the call request includes third signature information, identity information of the calling device, session information, and call service information; the third signature information is obtained by signing the identity information, the session information and the call service information of the calling equipment by using a private key of the calling equipment. The video color ring back tone server can decrypt the third signature information by using the public key of the calling equipment, so that the validity of the calling equipment is verified, and the first signature information, the video color ring back tone information and the identity information of the server are sent to the calling equipment after the verification is passed, wherein the first signature information is obtained after the private key of the server signs the video color ring back tone information and the identity information of the server.
In step S402, the calling device receives the information sent by the server, and proceeds to step S403 after the authentication is passed.
Specifically, after the validity of the calling device is verified, the video color ring server sends first signature information, the video color ring information and the identity information of the server to the calling device, wherein the first signature information is obtained by signing the video color ring information and the identity information of the server by using a private key of the server. Therefore, in this step, the calling device receives the first signature information, the video color ring information and the identity information of the server sent by the server, and verifies the first signature information according to the video color ring information, the identity information of the server and the public key of the server.
Step S403, after the verification is passed, the calling device plays the video color ring appointed by the video color ring information.
