I am trying to find the plain text for the following cipher text using a frequency analysisvr pvst yqlp mq nvfBut 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 eq 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 = tand v = hthat means p doesn't correspond to t anymore? Thanks in advance!
