Rogue Key Attacks on Lu et al.'s Verifiably Encrypted Signature Scheme
At Eurocrypt' 2006, Lu et al. proposed a pairing based verifiably encrypted signature scheme (the LOSSW-VES scheme) without random oracles. In this letter, we show that the LOSSW-VES scheme does not have opacity against rogue-key attacks.
