In today’s interconnected world, the need to access
to services across domains is increasing. How to
make inter-domain data exchanges secure is what we
concerned. Kerberos protocol can be used to secure
inter-domain information exchanges, but it cannot be
applied directly in environment where boundary
device such as firewall exists between domains. Proxy
ElGamal encryption scheme is a way to protect data
exchanges between two domains. However, there are
two disadvantages in using this proxy cryptosystem.
In this article, an improved proxy ElGamal
cryptosystem is proposed and two secure
inter-domain authentication and proxy keys
distribution protocols based on the improved proxy
ElGamal cryptosystem are designed, one is for
trusted domains and the other is for untrusted
domains. The proposed protocols make data
exchanges between domains more secure and
efficient.
