Abstract :
A novel type of proxy signature, multiple grade blind proxy signature, is proposed for the first time. It has the properties of both blind proxy signature and multiple grade proxy signature. Then the multiple grade blind proxy signature scheme is proposed based on the intractability of the discrete logarithm. The scheme not only keeps blind proxy for each grade, but also minimizes parameters from superior to subordinate, which improves the efficiency.
