Chapter 1 - Introduction to NetX Duo Crypto

NetX Duo Crypto is a high-performance real-time implementation of cryptographic algorithms designed to provide data encryption and authentication services. NetX Duo Crypto is designed to plug in for NetX Duo Secure TLS, DTLS, and IPsec modules. Applications may also use NetX Duo Crypto as a standalone module outside network security.

NetX Duo Crypto Unique Features

NetX Duo Crypto is implemented in the standard C language (C99), compatible with virtually all C/C++ compilers. Its modular design allows an application to only link in the crypto algorithms it needs to use, therefore achieving minimal code size. The implementation is designed to work with most 32-bit microprocessors and uses only the basic math operations (addition, subtraction, multiplication, division, logical AND, OR, NOR, and bit shift operations). All these operations are used with 32-bit quantities, making NetX Duo Crypto portable across most 32-bit microprocessors. The implementation is specifically optimized to run on resource constrained microprocessors, targeting deeply embedded applications.

Algorithms supported by NetX Duo Crypto
