| Abstract(in English) | Until now, it is not sufficiently discussed about how to construct a provably secure "partially blind signature with traceability"(PBST) by which functions of both the partially blind signature and the fair blind signature. This paper describes an application that the function of PBST is actually demanded, and specifically defines PBST and some security requirements of it. Subsequently, this paper proposes two kinds of PBST protocols and then considers the security of these according to the security requirements where they are previously defined. |
