  • Patent number: 11601405
    Abstract: Decoding includes sensing a packet related to SSL handshake for connecting a SSL between a client and a server after a TCP session has been established between the client and the server in an SSL decoding device. If the packet for an SSL handshake is transmitted in a preset operating system, an SSL between the client and the SSL decoding device and an SSL between the SSL decoding device and the server is established. A TCP session between a virtual client corresponding to the client and a virtual server corresponding to the server is also established. A packet transmitted/received between the virtual client and the virtual server is transmitted when the TCP session is established. If a first SSL packet transferred from the client to the SSL decoding device is received, the SSL packet is decoded and transmitted to the security device and to the server.

  • Patent number: 10374881
    Abstract: Provided is a method of subscribing, by a terminal, to a network as a router or an end device in a wireless network (WN) having a tree structure including routers and end devices. Each router receives, from a parent router thereof, addresses which are usable independently for child routers and child end devices thereof, and classifies the addresses into a general address and a special address. A terminal wishing to subscribe to a network may subscribe to the network by using a special address of an end device, only when the terminal is unable to subscribe to the network by using a general address of the end device, thereby reducing depletion of addresses to be used for terminal subscription and facilitating network subscription of the end device.
