摘要: The Andrew Secure Remote Procedure Call RPC is a protocol that allows two parties to establish new cryptographic key. was originally designed work on the network of Carnegie Mellon University, USA. Its concept and method can now be used enhance security communications different modules in smart cards, computer networks Internet. There have been many varieties since it designed. We questioned whether or not those existing were really secure efficient. It shown this paper most them are indeed secure, their efficiency improved. carried out analyses experiments illustrate our proposed here more 25% efficient, terms speed, than others.
