11.11 Symmetric Key Embedded

Encryption Library

Microchip offers a reliable security solution for

embedded applications built on the dsPIC33F platform.

This solution is provided by means of two libraries –

Symmetric Key and Asymmetric Key Embedded

Encryption Libraries. The Symmetric Key Library

includes the following:

Hash functions

- SHA-1 Secure Hash Standard

- MD5 Message Digest

Symmetric Key Encryption/Decryption functions

- Advanced Encryption Standard (AES)

- Triple Data Encryption Standard (Triple-DES)

Random Number Generator functions

- Deterministic Random Bit Generator

ANSI X9.82

Some typical applications for this library include:

Mobile and Wireless Devices, PDAs

Secure Banking

Secure Web Transactions

- Secure Socket Layer (SSL)

- Transport Layer Security (TLS)

- Secure Multipurpose Mail Extensions (S/MIME)

ZigBee Technology and other Monitoring and

Control Applications

Smart Card Readers/Trusted Card Readers

Friend/Foe Identification

Secure devices and peripherals interoperating

with TCG (Trusted Computing Group) and

NGSCB (Microsoft Next Generation Secure

Computing Base) personal computers

Key features of the Symmetric Key Embedded

Encryption Library include:

C-callable library functions developed in MPLAB

ASM30 assembly language

Optimized for speed, code size and RAM usage

- RAM usage below 60 bytes

Library functions extensively tested for adherence

to applicable standards

Symmetric Key Encryption/Decryption functions

support multiple modes of operation:

- Electronic Code Book (ECB) mode

- Cipher Block Chaining with Message

Authentication (CBC-MAC) mode

- Counter (CTR) mode

- Combined CBC-MAC and CTR (CCM) mode

“dsPIC30F Embedded Encryption Libraries User’s

Guide”

Several examples of use are provided for each

library function

11.12 Asymmetric Key Embedded

Encryption Library

Microchip offers a reliable security solution for

embedded applications built on the dsPIC33F platform.

This solution is provided by means of two libraries –

Symmetric Key and Asymmetric Key Embedded

Encryption Libraries. The Asymmetric Key Library

includes the following:

Public Key Encryption/Decryption functions

- RSA (1024 and 2048-bit)

Key Agreement Protocol

- Diffie-Hellman (1024 and 2048-bit)

Signing and Verification

- DSA (1024-bit)
