Abstract

The embodiment of the invention provides a data transmission method and system based on a block chain. The method comprises the steps: an equipment authentication platform obtains the recognition information of intelligent laundry equipment, generates a symmetric key and a public and private key pair according to the recognition information, and stores the symmetric key and the public and private key pair in a block chain server node, the recognition information and the intelligent laundry equipment are in one-to-one correspondence; the intelligent laundry equipment encrypts to-be-transmitted data by using a symmetric key, digitally signs the encrypted data by using a public and private key pair to obtain signed data, and sends the signed data to a block chain server node; and the blockchain server node performs signature verification on the signed data, decrypts the encrypted data when verification succeeds, analyzes the decrypted data, and links the analyzed data. According to the embodiment of the invention, the data transmission process is safer and more reliable, and the confidentiality and authenticity of the data are improved.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a block chain-based data transmission method and system. Background technique [0002] With the development of IoT technology, more and more IoT devices are connected to the Internet. Many IoT-driven shared devices are also developing very rapidly, such as shared bicycles, shared charging treasures, and shared smart laundry equipment. [0003] In related technologies, the Internet of Things cloud platform for cleaning and care allocates a shared smart laundry equipment interface for each operator, and the shared smart laundry equipment is authenticated on the cloud platform for cleaning and care through the interface. Then, when users need to use the shared smart laundry equipment, the corresponding The shared smart laundry equipment of the company sends user identity information to the laundry care IoT cloud platform, so that the laundry care IoT cloud ...
