Chapter 12. IPSec Futures
While IPSec is a versatile and functional protocol for securing IP, it is not a complete solution for all deployments, and there are still other issues that may need to be addressed. Many protocols desire to use IPSec to satisfy their security concerns and these have different problems that IPSec addresses incompletely. Indeed, while IPSec is a solution to a large problem, it is a problem to other protocols—for instance, network address translation (NAT).
Compression algorithms work by detecting patterns in data and eliminating duplicates. Encryption renders plaintext into seemingly random ciphertext. The better the encryption algorithm, the more random the ciphertext will appear. Regardless of the algorithm, ...
