Embodiment
Handheld device need to be set up wireless connections with designated equipment, the work that just can complete configuration and obtain facility information.According to circumstances different, handheld device adopts respectively two kinds of different modes and equipment to communicate:
First kind of way: as shown in Figure 2, the field apparatus N2 of handheld device H1 and appointment sets up point-to-point subnet, once this point-to-point subnet is established, handheld device will be regarded as believable equipment, allows itself and field apparatus N2 to carry out safe point-to-point communication.Owing to not needing other routing device to participate in the transmission of data, therefore adopt the encryption of link layer just can guarantee the fail safe of data.Set up point-to-point secure communication subnet process as follows:
1) user's input configuration key of handheld device H1, starts configuration software after success;
2) handheld device H1 specify network number and channel under, the broadcast of audiomonitor, search can be set up point-to-point equipment, as shown in the figure, now has 4 equipment that can set up communication, comprises routing device R1 and field apparatus N1, N2, N3;
3) forming device list on handheld device H1 (R1, N1, N2, N3), user selects the equipment N2 that wants to connect as required;
4) handheld device and field apparatus N2 carry out time synchronized, and that determines N2 adds transmitting-receiving time slot, and following communication process is all to carry out at the transmitting-receiving time slot that adds of N2;
5) handheld device H1 generates the message identifying of encrypting, and then sends to field apparatus N2.What this message comprised H1 adds key HJK, and adopts symmetric encipherment algorithm to be encrypted at link layer, and encryption key is HJK.
6) field apparatus N2 receives after message identifying, use the key NJK that adds of N2 to be decrypted at link layer, what after deciphering, extract handheld device H1 adds key HJK, relatively whether HJK is identical with NJK, if the same think that handheld device H1 possesses the qualification of setting up point to point network, N2 session key generation SK, sends to H1 after the message use key NJK that comprises SK is encrypted;
7) handheld device H1 receives after the response message of field apparatus N2, and point-to-point subnet is set up.After this handheld device H1 uses session key SK to carry out safe communicating by letter with field apparatus N2.
Which is used and adds key to carry out authentication, uses session key to encryption of communicated data, and authentication and encryption all adopt symmetric encipherment algorithm, and are completed by the encryption chip of device interior, have speed feature fast, low in energy consumption; Point-to-point subnet can not exert an influence to the communication of other equipment in WIA-PA network simultaneously.
The second way: as shown in Figure 3, in the time that handheld device H1 need to communicate with field apparatus N4, N4 has exceeded the communication range of H1, and now H1 need to add WIA-PA network, could communicate with N4.In order to guarantee the communication security end to end of H1 and N4, need to be encrypted at link layer and application layer, use asymmetric arithmetic to be encrypted in application layer, use symmetry algorithm to encrypt at link layer.Handheld device H1 adds WIA-PA network, and the process of communicating by letter with N4 is as follows:
1) user's input configuration key of handheld device H1, starts configuration software after success, after startup software, select to add WIA-PA network;
2) handheld device H1 is under the network number of specifying and channel, the broadcast of audiomonitor, the routing device that search can connect, if comprise multiple routing devices that can connect, according to factors such as jumping figure, signal strength signal intensity and loads, select optimal routing device, as shown in the figure, select routing device R1;
3) handheld device and routing device R1 carry out time synchronized, and that determines R1 adds transmitting-receiving time slot, and following communication process is all to carry out at the transmitting-receiving time slot that adds of R1;
4) handheld device H1 generates the networking message identifying of encrypting, and then sends to routing device R1.This message comprises adding key HJK and PKI PUBKEYH and adopting symmetric encipherment algorithm to be encrypted at link layer of H1, and encryption key is HJK.
5) routing device R1 receives after the networking message identifying of H1, use the key RJK that adds of R1 to be decrypted at link layer, what after deciphering, extract handheld device H1 adds key HJK, relatively whether HJK is identical with RJK, if the same think that handheld device H1 possesses the qualification that adds WIA-PA network, for H1 allocate communications time slot, Link message is sent to H1 after link layer encryption.R1 joins the PKI PUBKEYH of H1 in list of public keys, upgrades after list of public keys, selects suitable time slot that list of public keys is sent to all nodes in WIA-PA network;
6) handheld device H1 receives after the response message of routing device R1, successfully joins WIA-PA network.
7) when handheld device H1 need to send data to field apparatus N4, in list of public keys, search the PKI PUBKEY4 of equipment N4, use PUBKEY4 to be encrypted application layer data, then use HJK to be encrypted at link layer, send to routing device R1;
8) routing device R1 receives after message, uses RJK deciphering at link layer, determines after down hop routing device R2 after deciphering, uses RJK to be encrypted at link layer, then issues routing device R2.R2 receives after message, and processing procedure is similar to R1, and message is sent to N4;
9) field apparatus N4 receives after message, uses encryption key JKN to be decrypted at link layer, after determining that this message sends to oneself, uses the private key of oneself to be decrypted in application layer, and a layer message is applied.
Which, in the time that handheld device H1 networks, is carried out authentication by direct-connected routing device to handheld device H1, and after authentication success, H1 adds WIA-PA network.When H1 and node device communicate, be encrypted at link layer and application layer, the encryption of link layer guarantees the fail safe of transmission path; The encryption of application layer guarantees the fail safe end to end of data.Asymmetric arithmetic has safe feature, but computational speed is slower, and the encryption in application layer only need to be encrypted at the originating end of communication, clearing end is decrypted, therefore use asymmetric arithmetic to be encrypted in application layer, in guaranteeing high safety, other equipment are not affected; And the encryption of link layer needs all nodes on transmission path all to participate in, therefore use symmetry algorithm, and completed by hardware chip, thereby reduce the impact on performance and power consumption.
In handheld device, comprise key management module, key management module is responsible for the following several keys of store and management: configuring cipher key, add key, session key, equipment list of public keys.Wherein configuring cipher key and encryption key use a kind of individual event hash algorithm, are stored in the flash of handheld device after calculating its cryptographic Hash.
