The invention relates to an
Internet of Things data transmission system and method based on
quantum encryption communication, and belongs to the technical field of network and
information security. The
system comprises a
client transparent proxy module, a
server front transparent gateway module and a
quantum key service platform. The
client agent realizes
system-level application traffic interception, uses an SIM card security element as a hardware trusted root, obtains a
plaintext in combination with a dynamic man-in-the-middle technology, and applies for
quantum session key encryption to the quantum key service platform when quantum
encryption is needed in matching; the
server-side front transparent gateway module applies for a quantum
session key to the quantum key service platform to decrypt and forward the quantum
session key; quantum session
key distribution is negotiated through calling and called collaborative keys. According to the method, the quantum session key automatic encryption and decryption can be carried out on the specified API interface data without modifying the existing mobile application and business service codes, and the method has the remarkable advantages of zero invasion, high safety, low time
delay, easiness in operation and maintenance, low cost and the like.
