GSI (Grid Security Infrastructure) was used proxy certificate for delegation in grid environment. However, the proxy certificate holder can not issue his own identity, not to prove that he is a known entity. Therefore, it can not satisfy the requirements of nonrepudiation and known signer in grids. In this paper, we propose a dynamic delegation scheme for grids using proxy signature. Our scheme can satisfy all the requirements of delegation.
