    摘要: A method, system on a chip, and computer system for generating more robust keys which utilize data occupying relatively small die areas is disclosed. Embodiments provide a convenient and effective mechanism for generating a key for use in securing data on a portable electronic device, where the key is generated from repurposed data and a relatively small amount. A multi-stage encryption algorithm may be performed to generate the key, where the first stage may include encrypting the secure data, and the second stage may include encrypting the result of a logical operation on the encrypted secure data with a unique identifier of the portable electronic device. A secret key may be used as the encryption key for each stage. The result of the second encryption stage may include the generated key which may be used to perform subsequent operations on the portable electronic device.
