Question

Set up an RSA public-key cryptosystem using primes p = 71, q = 31 and a public exponent of 191 by finding the appropriate (positive) private exponent using the extended euclidean algorithm given the table below and identities:

ri = ri+1qi+1 + ri+2,          si+2 = si − qi+1si+1       and           ti+2 = ti − qi+1ti+1       si(a) +ti(b)=ri
