Latest Patents
One of Chi-Yi Shao's latest patents is an "Anti-tampering detector and method for detecting physical attack." This invention includes a temperature sensor, a voltage detector, a frequency detector, and a controller. The temperature sensor generates a temperature code based on the operational temperature. The voltage detector produces a voltage code according to the supply voltage and the temperature code. The frequency detector generates a frequency code based on the system clock, temperature code, and voltage code. The controller then uses these codes to determine if any tampering has occurred due to a physical attack.
Another notable patent is the "Key storage device and key generation method." This device comprises a first key unit and a second key unit. The first key unit outputs a first logic value through a first setting circuit and a first inverter. The second key unit similarly outputs a second logic value through a second setting circuit and a second inverter. The design ensures that the first threshold voltage is lower than that of the second threshold voltage, enhancing the security of the key storage device.
