QUESTION

What happens if the random number k used in creating the above DSS signature is compromised?

  1.  What happens if the random number k used in creating the above DSS signature is compromised?
  2.  DSS specifies that if the signature-generation process results in value of s = 0, a new random number k should be generated and the signature should be recomputed? Why?
  3. What happens if the hash function is not secure in DSS (this means that for a = h(m), one can easily find another m′ such that a = h(m′)?
