Abstract
When a user and a service provider carry out the authentication process, a user’s identity may be exposed and this issue has become a serious social problem. To solve this problem, identity escrow scheme is suggested. In the identity escrow scheme, the issuer who has accurate user identity safely transmits anonymous authentication information to the user and by utilizing this information, the user proceeds authentication steps with the service provider while keeping anonymity. In this thesis, requirements for security and trusty of the identity escrow scheme are suggested and new mechanism is proposed to satisfy them. Also, methods for a service provider to safely transmit the contents to the user and improved mechanism able to support key escrow in encryption communication using the key generated by key agreement among users in the same domain are proposed.
