Blind RSA signatures

public key: n, e
private key: d
blinding factor: k

Blinded message: t = m * k^e (mod n)
Blinded Signed: s_b = t^d (mod n)
Normal signed: s = s_b / k (mod n)

s = (t^d) / k (mod n)
s = (m * k^e)^d / k (mod n)
s = (m^d * k^e*d) / k (mod n)
s = (m^d * k) / k (mod n)
s = m^d (mod n)
