SMS encryption and decryption by SIM-Card (USIM)

Post by mhsnmaghsoodloo » Mon Nov 20, 2017 11:02 am

Hello everyone,
I Want to write a javacard applet for SIM-Card (USIM) to encrypt and decrypt SMS for specific number. i don't want to install any application on mobile phone and SIM-card applet has to detect the message is belong to specific number and encrypt or decrypt it. Can i write such javacard applet by SIM toolkit package or anything else to do this process technically?
Thanks a lot,
