Embodiment Construction
[0036] Embodiments of the present invention provide a communication method, system, and device between a convergence node and a mobile communication network. In the method, the convergence node receives the first random number returned by the VLR, and encrypts the first random number with a second private key stored by itself. , and return the second public key saved by itself and the encrypted first random number, the VLR uses the second public key to decrypt the encrypted first random number, when the decryption result is the same as the first random number, Receive data information sent by the sink node. Since the aggregation node in the embodiment of the present invention encrypts the first random number with the second private key, the VLR uses the second public key to decrypt the encrypted first random number, and according to whether the decryption result is the same as the first random number, Judging whether the convergence node is safe, and receiving the data informa...

The invention discloses a method, a system and a device for communication between a sink node and a mobile communication network, which are used for solving the problem of poor safety of data information sent to a VLR (visitor location register) by the sink node. The sink node receives a first random number back from the VLR, encrypts the first random number by a second private key, and feeds a second public key and the encrypted first random number back, and the VLR deciphers the encrypted first random number by the second public key and receives data information sent by the sink node when the deciphered result is identical with the first random number. Since the sink node in the embodiment utilizes a second private key to encrypt the first random number, the VLR utilizes the second public key to decipher the encrypted first random number, judges whether the sink node is safe or not according to whether the deciphered result is identical with the first random number or not, receives the data information sent by the sink node if in safe, and accordingly safety of data information sent to the VLR by the sink node is improved.
Description
technical field [0001] The present invention relates to the field of wireless communication, in particular to a communication method, system and device between a convergence node and a mobile communication network. Background technique [0002] The Internet of Things is an important part of the new generation of information technology, and the Internet of Things can be composed of wireless sensor networks and mobile communication networks. Among them, the wireless sensor network includes sensor nodes and sink nodes equipped with various types of sensors. The sensor nodes are used to detect and perceive the surrounding environment, and the sink nodes are used to receive data information sent by other sensor nodes, and the received data The information is sent to the user's terminal through the mobile communication network, so that the user can learn the data information he is interested in. Therefore, how to ensure the communication security between the aggregation node and ...
