| Abstract(in English) | The business through the network is being expanded with the spread of the Internet in recent years. However, the Internet is not equipped with the function s required for business or fair contracts. These functions require some characteristics such as authentication, confidentiality, integrity, non-repudiation, fairness and efficiency. Then, Certified E-mail is considered as a system which realizes such characteristics. Various systems and commercialization as Certified E-mail are proposed. Especially, Abadi's proposal system [AGHP02] requires small number of times of communication and also has few amounts of transmission to TTP. However, sender is authenticated by password shared with receiver, so the burden of preparation and management of passwords becomes large for both users when dealings partners increase in number. Then, in this paper, we modify the authentication method of Abadi's system. The modification is that the sender also makes pre-registration of a password with TTP. This modification realizes the system with which a user side should just prepare only one password when there are many partners. |
