I am trying to find the plain text for the following cipher text using a frequency analysis
vr pvst yqlp mq nvf
But for the letters above this is really difficult, as if I use the alphabetic substitution technique, where I assume that v corresponds to e as this occurs most in the english alphabet. What about p, this also occurs three times, does this mean it corresponds to e. Same for
r,s,t,y,l,m,n,j,f which occur only once. Is there an algorithm which looks at such duplicated frequencies, or do I guess:
v and p corresponds to e q corresponds to t r to f correspond to a
even using the bigram method for something like this is difficult as a bigram of pv is found, if p = t and v = h that means p doesn't correspond to t anymore?
Thanks in advance!
