DSC Symmetric Key Embedded
Encryption Library
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 Symmetric Key Library
features the following:
• Hash Functions:
- SHA-1 Secure Hash Standard
- MD5 Message Digest
• Symmetric Key Encryption/Decryption Functions:
- Advanced Encryption Standard (AES)
- Triple Data Encryption Algorithm
(Triple-DES)
• Random Number Generator Functions:
- Deterministic Random Bit Generator
ANSI X9.82
Features
• 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 Counter (CCM)
mode
• A comprehensive
“dsPIC30F Embedded
Encryption Libraries User’s Guide”
describing the
required APIs for the library functions
• Several examples of use are provided for each
library function
