CPKtec deliver top-quality, high-performance cryptographic technology for resource-constrained environments.

The CPKtec Cryptographic Toolkit provides a wide range of implementations of cryptographic algorithms, each designed for a particular combination of performance and code size. CPKtec systems combine maximum performance with minimum code size and minimum memory usage.

CPKtec can provide customers with custom-designed systems, configured to individual memory and performance requirements, using highly engineered, ready-built technology, with minimum time-to-market and low integration costs.

The CPKtec Cryptographic Toolkit

The CPKtec toolkit provides full implementations of the following cryptographic standards:

• RSA encryption, decryption and key generation
• Diffie-Hellman key exchange
• DSA (Digital Signature Algorithm)
• ECC (Elliptic Curve Cryptography, including ECDSA and key exchange) in characteristic p and in characteristic 2
• Symmetric algorithms, including AES (Advanced Encryption Standard), DES (Data Encryption Standard), 3DES, and ARC4, all in ECB (electronic codebook) and CBC (cipher block chaining) modes
• Hash functions including SHA-1 (Secure Hash Algorithm) and the MD5 message digest algorithm

Features

• Standards compliant
• Modular, with required functionality chosen at build (link) time
• Written in object-oriented C and assembler
• Each module available in a wide variety of size/speed versions
• A simple upper-level API (in C or C++)
• Support for various memory models - heap, embedded etc
• Highly portable, including to DSPs
• Completely self-contained - no use of C standard library
• Configurable use of precomputed data
• Multi-thread hardened throughout - no writeable global data
• Assembler optimisations for Pentium, ARM7TDMI and 68000 series; others on request
