Digraph probabilities

 

 
Frequencies of occurrence of each of the possible 256*256=2^16 pairs of consecutive output bytes (Output[x], Output[x+1]) were measured in a stream of 2^40.1 output bytes generated by the VMPC Stream Cipher. With consideration of the fact that 65536 variables were tested - none of the measured frequencies showed a statistically significant deviation from its expected value of 1 / 65536.
