The invention discloses an Internet of Things gateway data encryption communication method based on a quantum random number key, relates to the technical field of data encryption, and solves the technical problem of low data encryption efficiency based on a quantum key in the prior art. According to the method, to-be-encrypted data is divided based on encryption efficiency, index tags are set for a plurality of sub-data through quantum random numbers, an encrypted data sequence is generated through sequential rearrangement and integration, and finally the encrypted data sequence is encrypted through a quantum key; according to the method, the quantum key only needs to be generated once for the same to-be-encrypted data, the quantity demanded for the quantum key is small, and the data encryption efficiency can be improved; according to the method, the to-be-encrypted data is analyzed based on the quantum encryption efficiency, the to-be-encrypted data is segmented according to the set rule, and the to-be-detec
