Efficient Unlinkable Sanitizable Signatures from Signatures with Rerandomizable Keys.
IET Information Security(2018)
摘要
A sanitizable signature scheme is a malleable signature scheme where a designated third party has the permission to modify certain parts of the message and adapt the signature accordingly. This primitive was introduced by Ateniese et al. (ESORICS 2005) and Brzuska et al. (PKC 2009) formalized the initially suggested five security properties. In the subsequent year, Brzuska et al. (PKC 2010) introd...
