  • Non-malleable Multiple Public-Key Encryption

    FUJIOKA Atsushi , FUJISAKI Eiichiro , XAGAWA Keita

    … We study non-malleability of multiple public-key encryption (ME) schemes. … The main difference of ME from the threshold public-key encryption schemes is that there is no dealer to share a secret among users; … and a sender can encrypt a message under ad-hoc multiple public keys of his choice. … In this paper we tackle non-malleability of ME. … We note that the prior works only consider <i>confidentiality</i> …
