Abstract
As computers and networks become popular, distributing information on the Internet is common in our daily life. In the past, e-mail has been the primary choice of exchanging information, but instant messengers are gaining popularity abroad and domestically because of their nature of getting immediate reponses. However a instant messenger services have the exposure of data on internet but clients use them without recognizing their exposure. It's like phone tapping. The coding technology using Public Key Cryptosystem has developed the public key infrastructure to be able to do the services of Access-control, Authentication, Confidentiality, Integrity. and Non-repudiation with internet. It is a thesis that suggests the certification protocol in a instant messenger using PKI(Public Key Infrastructure) for secure communication.
