  • Publication number: 20120144205
    Abstract: An apparatus and method for preventing information leakage attacks that utilize timeline alignment. The apparatus and method inserts a random number of instructions into an encryption algorithm such that the leaked information can not be aligned in time to allow an attacker to break the encryption.
    Type: Application

  • Publication number: 20070258503
    Abstract: Disclosed are embodiments of an improved on-chip temperature sensing circuit, based on bolometry, which provides self calibration of the on-chip temperature sensors for ideality and an associated method of sensing temperature at a specific on-chip location. The circuit comprises a temperature sensor, an identical reference sensor with a thermally coupled heater and a comparator. The comparator is adapted to receive and compare the outputs from both the temperature and reference sensors and to drive the heater with current until the outputs match. Based on the current forced into the heater, the temperature rise of the reference sensor can be calculated, which in this state, is equal to that of the temperature sensor.
