Latest Patents

Suhas Sastry holds a patent for a "Hardware module-based authentication in intra-vehicle networks." This invention introduces a secure hardware-based module, known as the Security Electronic Control Unit (SECU), designed for the Controller Area Network (CAN). The SECU prevents attackers from sending malicious messages through the CAN bus, which could potentially take over control of a vehicle. The SECU shares a unique key and counter with each Electronic Control Unit (ECU) on the CAN bus. When a legitimate ECU sends a message, it compresses the message and generates a Message Authentication Code (MAC) using the counter and a secret key. The counter is incremented for each transmitted message. The ECU then fits the compressed message and the MAC into a single CAN frame and sends it onto the CAN bus. The SECU performs message verification on behalf of the intended receiver(s). If the verification is successful, the receiver(s) decompress the message and use it as a normal CAN message. If the verification fails, the SECU corrupts the CAN frame before it is fully received, ensuring that malicious messages generated by attackers inflict no damage on the system.
