Ecclesiastical ring the new pope. The pope's ring is not to be confused with the papal seal, which is what the pope uses to seal documents. The Fisherman's Ring is no longer used to seal anything. Except Pope Benedict XVI, who chose to wear his at all times, the ring had not been seen being publicly worn by a pope since the papacy of Pope Pius XII, who refrained from wearing it once his election ceremonies had been concluded. A collection of rings belonging to the popes of the past is exhibited in a glass case in a room within the papal
Ring signature a symmetric encryption function formula_14: In the ring signature scheme, the output formula_16 is the same as the input. This function is trivially invertible given formula_17 parameters. Generating a ring signature involves six steps. The plaintext is signified by formula_18, the ring's public keys by formula_19. Signature verification involves three steps. Here is a Python implementation of the original paper using RSA. To sign and verify 2 messages in a ring of 4 users: The CryptoNote technology uses ring signatures. It was first implemented by Bytecoin. The cryptocurrency ShadowCash uses traceable ring signature to anonymize the sender of a transaction.
