Abstract: The exponential growth of IoT makes it an increasingly tempting target for attackers. In addition to pure software vulnerabilities (like weak or hardcoded passwords, insecure data transfer and storage), the OWASP IoT Top Ten also lists hardware-related vulnerabilities such as the lack of physical hardening and the omission of a secure update mechanism. Mitigating these challenges requires additional hardware, as many of these devices are physically exposed and thus at a higher risk than conventional IT devices. More types of hardware solutions that implement the required functionality are entering the market; however, there are few to no performance comparisons. This lack further hinders the adoption of adequate solutions on a per-project basis. This white paper compares the performance of an MCU with an on-chip cryptographic engine to secure elements that connect to the host MCU over a serial bus.
