How to prove a list c0,...,cN-1 containing an encryption of 1?

[3for]

Hi, I've read both the Short Accountable Ring Signatures Based on DDH and One-out-of-Many Proofs: Or How to Leak a Secret and Spend a Coin papers. Is there any typo wrong in the Fig.5 algorithm of Short Accountable Ring Signatures Based on DDH? I'm not sure the correction in the picture below is correct?

Hi, There is no typo,
In our implementation in place of Enc() we are using Com(), for example Com(0, z)
