dsPIC®Asymmetric Key Embedded Encryption Library

Cryptographic Functions

Notes:

1. All library functions use the stack and require input and output message buffers to be set up by the calling application. Stack usage is below 100 bytes of RAM.

2. If more than one primary function is used in an application, code size required by the library will be less than the sum of code sizes for individual primary functions.

Summary

Microchip offers a reliable security solution for embedded applications built

on the dsPIC30F platform. This solution is provided by means of two

libraries – Symmetric-Key and Asymmetric-Key Embedded Encryption

libraries. The Asymmetric-Key library implements the following:

Typical Applications

The algorithms supported by this library have emerged as the defacto

standard for many large-scale, secured applications like web access, e-mail,

secure XML transactions, and virtual private networks (VPN). These

algorithms are also recommended by most Internet Engineering Task Force

(IETF), Federal Information Processing Standards (FIPS) and IPSec

Standards. Some typical applications for this library include:

The Trusted Computing Group (TCG) and related Microsoft Next Generation

Secure Computing Base (NGSCB), both specify RSA and Triple-DES. AES,

Triple DES and other symmetric solutions are featured in the dsPIC30F

Symmetric Key Embedded Encryption Library (SW300050).

Primary Functions

RSA

Diffie-Hellman

DSA

Auxillary Functions

Big Integer

Package

Deterministic

Random Bit Generator

SHA-1

MD5

For example, if RSA Signing/Verification and Diffie-Hellman Key Agreement are both used by an application, the library code size linked into the application is 3246 bytes,

which is significantly lesser than (2658 + 2067) bytes.
