In this paper, we propose new DSA-verifiable signcryption schemes. At ICISC '01, Yum and Lee first introduced the need for the public verifiability using standardized signature schemes and they proposed a KCDSA-verifiable scheme [1]. However, no DSA-verifiable signcryption schemes have been proposed. Additionally, we show some potential weakness of previous schemes proposed in [1, 2].
