Abstract
The communication system includes a communication buffer and a communication terminal. The communication buffer includes a physical unclonable function (PUF) device, and the communication buffer provides a security key generated by the PUF device. The communication terminal is coupled to the communication buffer, and transmits a mapping request to the communication buffer to ask for the security key. The communication terminal manipulates the transmission data with the security key to generate the encrypted data, and transmits the encrypted data to the communication buffer. The communication buffer further restores the transmission data from the encrypted data according to the security key.
Claims23
A communication system comprising:
- a communication buffer comprising a physical unclonable function (PUF) device, and the communication buffer being configured to provide a first security key generated by the PUF device;
- and
- a first communication terminal coupled to the communication buffer, and configured to transmit a first mapping request to the communication buffer to ask for the first security key, manipulate transmission data with the first security key to generate first encrypted data, and transmit the first encrypted data to the communication buffer;
- wherein the communication buffer is further configured to restore the transmission data from the first encrypted data according to the first security key.
A communication system comprising:
- a communication buffer comprising a physical unclonable function (PUF) device, and the communication buffer being configured to provide a security key generated by the PUF device, and manipulate transmission data with the security key to generate encrypted data;
- and
- a first communication terminal coupled to the communication buffer, and configured to transmit a mapping request to the communication buffer to ask for the security key, restore the transmission data from the encrypted data according to the security key, and perform a corresponding function according to the transmission data.
