Abstract
In the last couple of years, identity based cryptography has got fruitful achievements [1,2,3,4]. This paper provides theoretical discussions for the provable-security of ID-based proxy signature primitive. First, we present a general security model for such schemes. Then we describe how to construct an ID-based proxy signature scheme with a secure ID-based signature scheme, and prove the construction’s security in the standard model. At last, we analyze the ID-based proxy signature scheme proposed by Zhang et.al.[4], and show that this scheme can be proven to be secure in the random oracle model.
