hal (nprofile…deta) Why does Bob send hash(r1, r2, a, c') to Alice in the first place? Afterall, can't Bob just send r1 and r2 to Alice, Alice challenges him by sending back a random number e and Bob sends back s = r + e*a. Wouldn't that also prove that he used the same private key for the signature and his pubkey?
