| Abstract: | To prevent the user from evading key eserow and protect the eserowed private key, we establish some relationshipbetween the digital certificate and the escrowed key. An eserow scheme based on discrete logarithm is Presented. We also describe theoperation process of sending and receiving message of the user. and how the government can obtain the plain text from the ciphertextwith the help of Eserow Agent. |
