Recently, Due to the ongoing increase in cyber attacks and the improved awareness of privacy protection, most Internet services encrypt the traffic by using security protocols. Existing security protocols usually have additional layer between transport layer and application layer, and they incur additional costs because of encrypting all the traffic transmitted. This results in unnecessary performance degradation because it also encrypts data that does not require confidentiality. In this paper, we propose TCP OENC(Optional Encryption) which enables users of the application layer to optionally encrypt only confidential data. TCP OENC operates by TCP option to allow the application layer to encrypt the TCP stream transmitted only on demand. And it ensures transparency between the TCP layer and the application layer. To verify this, we verified that TCP OENC optionally encrypts the stream of TCP session on the embedded board. And then analyzed the performance of the encrypted stream by measuring the elapsed time.
