Abstract
Because the Internet is vast and insecure, strong cryptographic protocols are required to support secure communication. In this paper, we propose an efficient way to perform secure delegations in a hierarchical group. We propose a practical multi-proxy signature scheme applicable to hierarchial organization using the Diffie-Hellman problem and secret sharing without secure channels. In addition, we improve the proposed scheme to a dynamic one allowing repeated delegations. © Springer-Verlag Berlin Heidelberg 2005.
