Abstract: The present invention provides a method, an apparatus, and a system for securely transmitting data. A method for securely transmitting data is provided, where the method includes: sending, by a user terminal, a resource access request carrying a first authentication header field to a server, where the first authentication header field includes a user identifier and a server identifier; and receiving a request response returned by the server, where the request response includes a second authentication header field and a message body, where the second authentication header field carries a third integrity digest, and the third integrity digest is obtained by the server by performing, after receiving the resource access request, calculation by using a third message-digest algorithm further according to a user password and message content; so that M2M transmission based on the CoAP protocol can be performed securely and reliably.

Abstract: Embodiments of the present invention provide a group communication method, system, group server, and group member device. A group server receives notification messages sent by a group member device, aggregates, according to an address of a subscription device, the notification messages destined for the same subscription device, and sends a notification message obtained after aggregation to the subscription device. By aggregating multiple messages sent by the group member device to the subscription device, messages exchanged between the group member device and the subscription device are reduced, thereby reducing communication traffic between the group member device and the subscription device.
