Controller Area Network (CAN) is the main bus network that connects electronic control units in automobiles. Although CAN protocols have been revised to improve the vehicle safety, the security weaknesses of CAN have not been fully addressed. Security threats on automobiles might be from external wireless communication or from internal malicious CAN nodes mounted on the CAN bus. Despite of various...
We propose three fault-tolerant methods for a new lightweight block cipher SIMON, which has the potential to be a hardware-efficient security primitive for embedded systems. As a single fault in the encryption (decryption) process can completely change the ciphertext (received plaintext), it is critical to ensure the reliability of encryption and decryption modules. We explore double-modular redundancy...
We propose a series of fine-grained splitting transmission methods to address permanent errors in Network-on-Chip (NoC) links, maintaining high throughput and ensuring reliability. While prior permanent error management approaches discard the entire or half link, our proposed methods greatly improve wire utilization in the presence of permanent errors. A case study shows that our methods achieve throughput...
We propose an error control method to comanage transient and permanent errors in the data link and physical layers of a network-on-chip (NoC). To reduce energy overhead, a configurable error control coding (ECC) unit adapts the number of redundant wires to the noise conditions, achieving a required error detection capability. Infrequently used redundant wires are utilized as spare wires to replace...
