Abstract
The invention relates to a transmission technology for realizing data security in circuit simulation equipment. The encryption and the secure transmission of data are realized through an IPSec protocol, thus the confidentiality and the integrity of the data can be guaranteed, and the data and a data source can be loaded and verified in an encryption mode. The purpose of enhancing the system security can be achieved by regularly updating and maintaining a key. Subjacent E1 or Ethernet equipment of the circuit simulation equipment can realize data security communication to target equipment through the circuit simulation equipment.
Description
Technical field
The present invention is a kind of transmission technology that realizes data security in circuit simulation equipment, realize the encryption and the safe transmission of data by IP Security agreement (hereinafter to be referred as IPSec), can guarantee the confidentiality and integrity of data, can encrypted payload data and verification msg source.Can reach the purpose that enhances system security by timing updating maintenance to key.E1 that connects under this equipment or ethernet device can be implemented to the data security communication of destination device by this equipment.
Background technology
Along with the mainstreaming of world-wide web and enterprise network, it is more and more important that the problem of network security also becomes, and relevant solution also becomes hot issue, for example PGP, Kerberos and SSL or the like.But, these solutions mainly all are to add security mechanism in application layer or the transport layer, and IPSec is the fail safe agreement that puts forward at network layer protocol.IPSec is not an independent agreement, it has provided a whole set of architecture of network data security on application and the IP layer, comprises network authenticating protocol Authentication Header (AH), encapsulating security payload (esp) Encapsulating Security Payload (ESP), IKMP Internet Key Exchange (IKE) and is used for network authentication and some algorithms of encryption.Stipulated how between peer layer, to select security protocol, determined security algorithm and cipher key change, Network Security Service such as access control, data source authentication, data encryption upwards are provided.IPSec is the part of IPv6, also is the optional Extended Protocol of IPv4.IPSec has remedied IPv4 lacks security consideration when design of protocol deficiency.
Summary of the invention
The present invention adopts ipsec protocol in circuit simulation equipment, be implemented in the safe transmission that guarantees data in open or the insecure network.
ECE becomes the IP packet to the E1 data by the HC-ETH2 protocol packing earlier, by IPsec the IP packet is encrypted then, thereby is realized the safe transmission of E1 data in open network.In the network of an opening, the communication between equipment and the equipment might be stolen by some the illegal users in the network, causes communication between devices to become dangerous, and in Fig. 1, the communication data between device A, the B is illegally obtained by user C.The present invention is exactly a kind of technical scheme that to propose in order addressing this problem and to realize.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified
Fig. 1 does not support data safe transmission equipment to transmit schematic diagram in explorative network;
Fig. 2 supports the circuit simulation equipment sending data schematic diagram of data safe transmission;
Fig. 3 supports the circuit simulation equipment receiving data schematic diagram of data safe transmission.
Embodiment
Among Fig. 2, realize that the concrete mode of the safe transmission of data is:, just use corresponding SA and encrypt or authenticate from the preferred circuit emulator as long as the packet that comes out meets security strategy.Whole safe transmission process is controlled by IKE, and key generates automatically, and the user in the protection subnet does not need to consider safety, and all encryption and decryption are by the circuit simulation equipment full powers agency at two ends.
Workflow of the present invention:
● (the supposition device A is the circuit simulation equipment of support data safe transmission to device A, and is data source.Earlier the E1 data are become the IP packet according to the HC-ETH2 protocol packing down together).Shown among Fig. 22;
● unencrypted IP packet is by the ipsec protocol block encryption.As 3 showing among Fig. 2;
● encrypted data send from Ethernet interface;
● equipment B (supposing that equipment B is for supporting the circuit simulation equipment of data safe transmission, down together) receives the data of process ipsec encryption shown in Fig. 31 from Ethernet interface;
● equipment B by the ipsec protocol piece to enciphered data deciphering and checking as among Fig. 32;
● equipment B is installed the HC-ETH2 protocol assembly by circuit simulation equipment becomes the E1 packet;
By above flow process, make packet in unreliable packet, pass through encryption, authentication techniques, make packet can obtain safe and reliable transmission.
