Abstract:
1. A method for encryption processing using an encryption algorithm in an encryption processing system to provide output data, comprising: (a) storing a state array corresponding to the encryption algorithm wherein the state array comprises a plurality of array values each of which is indexed using one of a plurality of indexes; (b) reading a first array value from the state array using a first index; (c) reading a second array value from the state array using a second index; (d) reading a third array value from the state array using a third index; (e) writing a first input array value to the state array substantially in parallel with reading the third array value; (f) determining the output data by comparing the first index and the third index and by comparing the second index and the third index and: (g) writing a second input array value to the state array substantially in parallel with determining the output data.
