An IoT device has a public device identifier and a private device identifier, where the public device identifier is publicly available and the private device identifier is secret but kept in a secure device database as a correspondence. A registration request is sent from the IoT device to an association server in communication with the device database having an association between IoT public identifier and a corresponding IoT private identifier. The association server which receives the registration request responds with a registration acknowledgement containing, in encrypted form, the private device identifier of the original request and, optionally, the public device identifier associated with the registration request. The requesting IoT device receives the association acknowledgement, decrypts the private device identifier, compares it to its own device identifier, and if they match, sends one or more association requests.

An apparatus, system, and method are disclosed for managing response latency. An identification module identifies a computation module that may communicate with a client through one or more communication modules. A calculation module calculates the number of communication modules that transceive a packet between the computation module and the client as a hop count. An association module associates the client with the first computation module in response to the hop count satisfying a count range of a response policy. In one embodiment, a trouble ticket module generates a trouble ticket in response to a specified number of clients having a hop count greater than the count range.

The embodiment of the invention provides a content centric network privacy protection method based on hybrid encryption and an anonymous group. An interest packet is transmitted through the anonymous group, and decrypted into a plaintext interest packet layer by layer in a node of the anonymous group, thereby effectively preventing an attacker from getting association between the interest packet and a user. Hybrid encryption is performed on the interest packet and a data packet through encryption methods such as a user ID, a public key and a private key of a publisher, a symmetric key, and a public key and a private key of the anonymous group, so that the data packet can be protected from being modified in a process from signature to reception by the user, and plaintext content cannot be cracked inversely within certain time even though the attacker gets encrypted communication content by eavesdropping, thereby protecting the privacy of communication data. In the embodiment of the invention, the identity privacy information of a signer is protected through construction of the anonymous group, and meanwhile unlinkability between communication content and both communication parties is realized through a hybrid encryption method.

The invention provides a resource selection method, a base station and a terminal, solving the problem that in an SPS mechanism mode, a malicious terminal may track the geographic position of a targetterminal by continuously determining information monitoring on resources, resulting in privacy leakage of the target terminal. The resource selection method comprises the step of triggering SPS resource reselection when a layer 2 ID is changed or the duration of semi-persistent scheduling SPS resources reaches the preset maximum duration. According to the resource selection method, when the layer2 ID changes or the duration of semi-persistent scheduling (SPS) resources reaches the preset maximum duration, the layer 2 ID is changed; and SPS resource reselection is triggered, so that the SPS resource is prevented from being kept unchanged for a long time, and the situation that the receiving node can associate different layer 2 IDs is avoided, and the probability of continuous tracking ofthe malicious terminal to the target terminal is reduced.
