Reassessing Security of Randomizable Signatures [chapter]

David Pointcheval, Olivier Sanders
2018 Lecture Notes in Computer Science  
This lack of precise security assessment is obviously a barrier to a widespread use of these signatures and a reason for preferring other constructions, such as the ones relying on q-type assumptions.  ...  In this paper, we study more thoroughly the security of these signatures and prove that it actually relies, for both constructions, on simple variants of the SDH assumption, assuming a slight modification  ...  Moreover, it also cancels the full randomizability of the signature since m cannot itself be randomized. But the purpose of m , in the security proof, is to provide a degree of freedom.  ...
