Overview:

Electronic mail is playing an important role for communication among Internet users. However, the value of electronic mail is being impaired by spam mails including unwanted commercial information, virus mails including malignant codes and many different forms of unnecessary information. Thus, it is urgent to develop a method of blocking spam mails fundamentally. The present paper proposes a method in which an electronic mail sender receives confidential information through SMS (Short Message Service) and creates a private key/public key pair used in the DomainKey method and, in connection with the existing PGP method, the email sender is authenticated and the message is encrypted/decrypted. Because the proposed method authenticates the sender in the process of mail transmission, it can prevent spam mails.
