detailed description

The core of the present invention is to provide an accelerated processing method and system for network security IPsec, using software to run the key exchange protocol and hardware to run the network security service protocol in parallel, thereby improving the processing speed of network security IPsec and reducing software resources. The utilization rate of, and increase the network bandwidth.

In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Please refer to FIG. 1. FIG. 1 is a flowchart of a network security IPsec acceleration processing method according to an embodiment of the present invention.

The accelerated processing method of the network security IPsec includes:

Step S1: Use the first sender software to generate a key exchange IP packet, and transparently transmit the key exchange IP packet to the first receiver's hardware through the first sender's hardware; wherein, the key exchange IP packet includes key data and The first IP address of the key exchange parties.

Specifically, different senders and receivers in the system have different requirements for data transmission security. For senders and receivers that require higher data transmission security, the transmission data needs to be encrypted and decrypted between the two Processing: For the sender and receiver with low data transmission security requirements, there is no need to encrypt and decrypt the transmitted data between the two. It is understandable that for the sender and receiver (called the first sender and the first receiver) that require high data transmission security, they must exchange keys before data transmission for subsequent encryption and decryption. Lay the foundation for data transmission.

Considering that the key exchange process between the first sender (first sender software + first sender hardware) and the first receiver (first receiver software + first receiver hardware) in the system requires low real-time performance, Therefore, this application uses the software of the first sender to generate a key exchange IP package that includes the key data and the first IP (Internet Protocol, network protocol) address of the key exchange parties (that is, the software runs the key exchange protocol). Among them, the key data is used for subsequent encryption and decryption of data transmitted between the first sender and the first receiver; the first IP addresses of both parties in the key exchange include the IP address of the first sender and the IP of the first receiver address.

After the key exchange IP packet is generated by the first sender software, the key exchange IP packet is sent to the first sender's hardware to be transparently transmitted to the first receiver's hardware through the first sender's hardware to complete the key exchange .

Step S2: Use the second sender software to perform IP packaging processing on the transmission data to obtain the data IP packet, and send the data IP packet to the second sender hardware; wherein the data IP packet includes the transmission data and the second IP of the data transmission parties address.

Specifically, when data is transmitted between the sender and the receiver in the system (referred to as the second sender and the second receiver), first use the second sender software to perform IP packet processing on the transmission data, and obtain the data including the transmission data. And the data IP packet of the second IP address of both parties of the data transmission; then the data IP packet is sent to the second sender hardware. Wherein, the second IP addresses of the data transmission parties include the second IP address of the second sender and the second IP address of the second receiver, so as to lay a foundation for the subsequent determination of whether the transmitted data needs to be encrypted or decrypted.

Step S3: Determine whether there is a second IP address in the first IP address; if yes, execute step S4; if not, execute step S5.

Specifically, it can be understood that if the second sender and the second receiver belong to the first sender and the first receiver mentioned in step S1, then the transmission data needs to be encrypted and decrypted later; if the second sender If the party and the second receiver do not belong to the first sender and the first receiver mentioned in step S1, there is no need to perform encryption and decryption processing on the transmission data subsequently.

Based on this, this application should determine whether the second sender and the second receiver belong to the first sender and the first receiver mentioned in step S1, specifically based on the IP address. If one IP address can match the second IP address of both parties to the data transmission, the second sender and the second receiver belong to the first sender and the first receiver mentioned in step S1; otherwise, the second sender And the second receiver does not belong to the first sender and the first receiver mentioned in step S1.

Step S4: On any idle pipeline among the multiple pipelines of the second sender's hardware, encrypt the data IP packet with the corresponding target key data, and send the encrypted data IP packet to the second receiver's hardware to On any idle pipeline among the multiple pipelines of the second receiver's hardware, use the target key data to decrypt the data IP packet.

Specifically, considering that the same sender may want to transmit data with different receivers, the same receiver may also transmit data with different senders, and the data transmission process between the sender and the receiver requires high real-time performance, Therefore, the sender's hardware and receiver's hardware of this application are both set as hardware with multiple pipelines, which can transmit multiple channels of data in parallel, and can encrypt and decrypt multiple channels of data in parallel (that is, the hardware runs the network security service protocol in parallel) .

It is understandable that when the second sender and the second receiver belong to the first sender and the first receiver mentioned in step S1, the transmission data needs to be encrypted and decrypted. Specifically, since the second sender and the second receiver have exchanged keys, the target key data in the key exchange IP packets corresponding to the second sender and the second receiver can be obtained. When the second sender transmits data to the second receiver, select an idle pipeline from the multiple pipelines of the second sender's hardware, and use the acquired target key data to encrypt the data IP packet on the idle pipeline, and then The encrypted data IP packet is sent to the second receiver hardware.

When the second receiver's hardware receives the encrypted data IP packet, it selects an idle pipeline from the multiple pipelines of the second receiver's hardware, and uses the obtained target key data to decrypt the data IP packet on this idle pipeline , So as to get the transmission data.

Step S5: Transparently transmit the data IP packet directly to the second receiver's hardware through the second sender's hardware.

Specifically, when the second sender and the second receiver do not belong to the first sender and the first receiver mentioned in step S1, there is no need to encrypt and decrypt the transmission data, and the data IP packet is directly sent through the second The hardware of the third party can be transparently transmitted to the hardware of the second receiver.

In addition, the present application may use the second sender's hardware to determine whether to perform encryption processing on the transmission data, and use the second receiver's hardware to determine whether to perform decryption processing on the transmission data. For the second sender's hardware, if the first IP addresses of the two parties in the key exchange can match the second IP addresses of the two parties in the data transmission, the transmitted data will be encrypted, otherwise it will be transmitted directly. For the second receiver's hardware, it receives both the encrypted data IP packet and the unencrypted data IP packet, so the second receiver's hardware first unpacks the data IP packet to obtain the first data transmission of both parties. Two IP addresses, if the first IP addresses of the two parties in the key exchange can match the second IP addresses of the two parties in the data transmission, the transmitted data will be decrypted, otherwise no decryption will be performed.

The present invention provides an accelerated processing method for network security IPsec. Because the key exchange process between the sender and the receiver has low real-time requirements, this application uses software to run the key exchange protocol; because the data between the sender and the receiver The transmission process requires high real-time performance, so this application uses hardware with multiple pipelines to complete the data transmission process, and in this process, multiple pipelines can be used to complete the encryption and decryption process of different data IP packets in parallel (that is, hardware parallel operation is used Network Security Service Protocol), thereby improving the processing speed of network security IPsec, reducing the usage rate of software resources, and increasing network bandwidth.

Further, considering that in the process of transparently transmitting the data IP packet directly to the second receiver's hardware through the second sender's hardware, there may be errors, causing the second sender's hardware to incorrectly encrypt the data IP packet and send it to the second receiver. The hardware of the receiver. At this time, the hardware of the second receiver cannot decrypt the received data IP packet. Therefore, this application will detect the second receiver’s hardware after transparently transmitting the data IP packet directly to the second receiver’s hardware through the second sender’s hardware. 2. The format of the data IP packet received by the receiver's hardware. If the format of the data IP packet is a normal format, it means that the data IP packet is not encrypted, that is, there is no error in the process of transmitting the data IP packet directly to the second receiver's hardware through the second sender's hardware; if the data IP When the packet format is the network security service protocol format, it means that the data IP packet is encrypted, that is, there is an error in the process of transmitting the data IP packet directly through the second sender's hardware to the second receiver's hardware, then the data IP The packet can be discarded.
