Microchip Technology Incorporated
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:
·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)
– RSA (1024 and 2048 bit)
·Hash and Message Digest Functions
– SHA-1, MD5
·Random Number Generator (RNG)
– ANSI X9.82
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:
·Mobile and Wireless Devices, PDAs
·Secure Banking
·Secure Web Transactions
– Secure Socket Layer (SSL)
– Transport Layer Security (TLS)
– Secure Multipurpose Internet Mail Extensions (S/MIME)
·ZigBee™ technology and other monitoring and control applications
·Smart Card Readers
·Friend/Foe Identification
·Peripherals interoperating with TCG and NGSCB personal computers
The Tr usted 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).

Execution Time
For a 1024-bit modulus, when the dsPIC30F device operates at 30 MIPS,
average execution times are provided below (in milliseconds):
·RSA Encryption and Verification functions execute in 7 ms for a
17-bit exponent
·RSA Decryption and Signing functions execute in 152 ms for a
17-bit exponent
·DSA Signing function executes in 80 ms
·DSA Verification function executes in 151 ms
·Diffie-Hellman key agreement executes in:
– 78 ms for 160-bit key
– 487 ms for 1024-bit key

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.
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.
