IP Security/Internet Key Ex改变

IPSec/IKE allows encryption of all data contents of IP packages. The keys can be replaced via the Internet (public/private key procedure).
Available encryption mechanisms: DES, Triple DES, AES (128, 192, 256 Bit), MDS, SHA-1, SHA-2 (256, 384, 512 Bit).

Specific features

• Specifically optimized for embedded applications (code size, memory requirement and performance)
• Easily portable via ANSI-C source code
• Adapted for NicheStack v4, NicheStack v6 and NicheStack Dual v4v6
• Can be used with or without operating system
