Class AesTestSeq

java.lang.Object

edu.rit.clu.monte.AesTestSeq

public class AesTestSeq
extends java.lang.Object

Class AesTestSeq is a sequential program that tests the randomness of the AES block cipher.

Usage: java edu.rit.clu.monte.AesTestSeq key N
key = Block cipher key
N = Number of blocks

The program:

• Initializes the AES block cipher with the key.
• Generates N ciphertext blocks by encrypting the plaintext blocks 0, 1, 2, and so on (counter mode).
• Takes the most significant halves of the 128-bit ciphertext blocks as a series of 64-bit long values.
• Divides the long values by 2⁶⁴, yielding a series of supposedly-random double values in the range 0.0 to 1.0.
• Performs a Kolmogorov-Smirnov (K-S) test on the data to try to disprove the null hypothesis that the data are drawn from a uniform distribution.
• Prints the K-S statistic and the p-value.

The computation is performed sequentially in a single processor. The program measures the computation's running time. This establishes a benchmark for measuring the computation's running time on a parallel processor.
