PPC-PROTECT - the system of software protection for Windows CE (PocketPC) applications with ARM core, designed for quick implementation of application protection functions. PPC-PROTECT is designed for such specific tasks as working with registration keys and creation of trial application versions.

PPC-PROTECT includes the following features:
- compression of the executable code and resources
- encryption of the application
- counteraction to debuggers and disassemblers
- application integrity check
- API for interaction between application and protection routines
- possibility to create evaluation (trial) versions, that limits application functions basing on evaluation time, expose nag-screens
- creation and verification of registration keys using public keys encryption algorithms (ECC) or using Reverse Polish Notation algorithms (RPN)
- generating of registration keys, based on the specific computer system
