As Pailliear cryptosystem secret key $\lambda$, depends on primes $p$ and $q$. As $\lambda = \operatorname{lcm}(p-1,q-1)$.

I want decryption key to independent from $p$ and $q$.

  • It can be possible to generate decryption key independently?
  • $\begingroup$ Could you tell the reason? Maybe you are asking x but want y. $\endgroup$ – kelalaka Sep 3 '19 at 14:05
  • $\begingroup$ Can it be possible to generate a decryption key without knowledge of $p, q$ (e.g. with only knowledge of $n = pq$) - we most certainly hope not, as that would imply that Paillier is insecure. $\endgroup$ – poncho Sep 3 '19 at 14:32
