Step S304, such as encrypts unsuccessful, then calls the spare cryptographic unit of the first ciphering unit that the packet is encrypted,
The packet header extended field of the packet after encryption will be added to using spare cryptographic unit marks.
Step S604, internet-of-things terminal is by the packet after encryption, the current time and the signal strength values
Carry and sent in the load of frame to Internet of Things access point.
Above-mentioned steps S604 implementation method can be：
Internet-of-things terminal sends packet to Internet of Things repeater (one kind of network side equipment) in above-mentioned steps S604
Mode can be that packet is sent by way of wireless connection, and the wireless mode includes but is not limited to：Bluetooth, Wireless Fidelity
(English：Wireless Fidelity, WIFI) or the wireless mode such as Zigbee, wherein, above-mentioned WIFI needs to observe
IEEE802.11b standard.
It should be noted that Internet of Things and internet-of-things terminal here be only just for wireless internet of things terminal, because
For for Internet of Things, the number of devices that it is accessed is numerous, for internet-of-things terminal, if by wired connection, it is first
The access quantity of first internet-of-things terminal can limit, and for family, with wired connection, for domestic consumer's
It can not imagine for wiring, this wired cost is also very high in addition, so the middle Internet of Things in technical scheme
Connection between network termination and Internet of Things repeater only limits wireless connection.
The technical solution adopted by the present invention has the advantages of safe.
Optionally, the above method can also include before step S604：
The internet-of-things terminal calls the first ciphering unit encryption unsuccessful, and the internet-of-things terminal calling first adds
