    摘要: A system and method for coding data to help resist differential attacks. Data in m columns may be initialized to an initialized value. One new column of data may be mixed with a new input word and input to an advanced mixer. The advanced mixer may include linear mixing having indexed bytes and performing of exclusive-OR operation and transposing. An output of the advanced mixer may be a new m column state. A value of m could be 0 through 30. The value of m may have a preferred range of 27 through 36. Systems to implement the foregoing method are also described.

    摘要: A method of performing biometric authentication of a person's identity including a biometric template prior to storing it in a biometric database. The encryption algorithm encrypts the biometric template using a pass-phrase, known only to the individual, to generate the cryptographic key used to store and retrieve the biometric template. When an individual wishes to access a secured resource, he must be authenticated by providing an identifier which is used to retrieve the appropriate record. He must also provide the correct password to allow the system to decrypt the model.
