How to enable encryption for an particular characteristics data?

Hi all,

I am new to work with security manager protocol with ble devices

I am working over nrf51822 board and I have run the code BLE_LED and it is working fine with my hardware. I have some security issues because I have declare some services and characteristics to work with ble device and when I am scanning it with nrf toolbox app it is showing characteristics UUID as well. I want that when the peripheral is advertising to connect with central then to connect with central, It should prompt a display for passkey so that MITM will not be able to use the ble services and characteristics which I have declared.

Please suggest me a good approach on how to work with the encryption of an particular characteristics data using either passkey or out of band pairing method. Thanks.
