  Abstract

Most of banks in Korea provide smartphone banking services. To use the banking service, public key certificates with private keys, which are stored in personal computers, should be installed in smartphones. Many banks provides intermediate servers that relay certificates to smartphones over the Internet, because the transferring certificates via USB cable is inconvenient. In this paper, we analyze the certificate transfer protocol between personal computer and smartphone, and consider a possible attack based on the results of the analysis. We were successfully able to extract a public key certificate and password-protected private key from encrypted data packets. In addition, we discuss several solutions to transfer public key certificates from personal computers to smartphones safely.
