User terminal safety communication method in platform of Internet of Things

The invention relates to a user terminal safety communication method in a platform of the Internet of Things, in particular to an implementation scheme for safety communication among multivariate and heterogeneous user terminals and platform servers. According to the method, a safe communication system model of the Internet of Things is established by mainly combining an ASN.1 (abstract syntax notation one) with safe encryption and decryption and authentication algorithms, so that a standard data packet structure is provided for authentication, interconnection and intercommunication among different programming languages, different operating systems, different types of computers and different types of hardware environments in the Internet of Things, and authentication and interactive both sides can be identified. Besides, a more efficient safety mechanism is introduced to enable different entities in the Internet of Things to be communicated safely, rapidly and reliably, so that resource cost and time delay during data transmission can be remarkably improved.
