-*'''Symmetrisation:''' Buyer and Verifier exchange half of their randomly chosen eliminated signature elements. This prevents a dishonest seller succeed in cheating by sending dissimilar public keys to the receiver and makes the protocol secure against repudiation. Thus ends the distribution phase.\end{itemize}
+*'''Symmetrisation:''' Buyer and Verifier exchange half of their randomly chosen eliminated signature elements. This prevents a dishonest seller succeed in cheating by sending dissimilar public keys to the receiver and makes the protocol secure against repudiation. Thus ends the distribution phase.
 Similarly, Messaging Phase is divided into the following steps:
 *'''Signing:''' Sender sends desired message and the corresponding signature to the desired receiver (called buyer). Buyer compares the private key with his eliminated signature for the corresponding message  and counts the  number of mismatches (eliminated signature element in seller's private key).
 *'''Transfer:''' Buyer forwards the same message and private key to the other receiver (called verifier) who compares it with his eliminated signature for this message.
