I'll write a separate module for that part.
|
||||
|
||||
I think we should even add a good PRNG that is re-seeded from
|
||||
/dev/?random frequently. GnuTLS can need a lot of random data on a
|
||||
big server, more than /dev/random can supply. And /dev/urandom might
|
||||
not be strong enough. Further, the security of /dev/?random can also
|
||||
be questionable.

|
||||
|
||||
There is none, that is the problem.
|
||||
|
||||
Applications generally need different kind of "random" numbers.
|
||||
Sometimes they just need some random data and doesn't care whether it
|
||||
is possible for an attacker to compute the string (aka a "nonce").
|
||||
Sometimes they need data that is very difficult to compute (i.e.,
|
||||
computing it require inverting SHA1 or similar). Sometimes they need
|
||||
data that is not possible to compute, i.e., it wants real entropy
|
||||
collected over time on the system. Collecting the last kind of random
|
||||
data is very expensive, so it must not be used too often. The second
|
||||
kind of random data ("pseudo random") is typically generated by
|
||||
seeding a good PRNG with a couple of hundred bytes of real entropy
|
||||
from the "real random" data pool. The "nonce" is usually computed
|
||||
using the PRNG as well, because PRNGs are usually fast.
|
||||
|
||||
Pseudo-random data is typically used for session keys. Strong random
|
||||
data is often used to generate long-term keys (e.g., private RSA
|
||||
keys).
|
||||
|
||||
Of course, there are many subtleties. There are several different
|
||||
kind of nonce:s. Sometimes a nonce is just an ever-increasing
|
||||
integer, starting from 0. Sometimes it is assumed to be unlikely to
|
||||
be the same as previous nonces, but without a requirement that the
|
||||
nonce is possible to guess. MD5(system clock) would thus suffice, if
|
||||
it isn't called too often. You can guess what the next value will be,
|
||||
but it will always be different.
|
||||
|
||||
The problem is that /dev/?random doesn't offer any kind of semantic
|
||||
guarantees. But applications need an API that make that promise.
|
||||
|
||||
I think we should do this in several steps:
|
||||
|
||||
1) Write a module that can read from /dev/?random.
|
||||
|
||||
2) Add a module for a known-good PRNG suitable for random number
|
||||
generation, that can be continuously re-seeded.
|
||||
|
||||
3) Add a high-level module that provide various different randomness
|
||||
functions. One for nonces, perhaps even different kind of nonces,
|
||||
one for pseudo random data, and one for strong random data. It is
|
||||
not clear whether we can hope to achieve the last one in a portable
|
||||
way.
|
||||
|
||||
Further, it would be useful to allow users to provide their own
|
||||
entropy source as a file, used to seed the PRNG or initialize the
|
||||
strong randomness pool. This is used on embedded platforms that
|
||||
doesn't have enough interrupts to hope to generate good random data.
|
||||
|
||||
> For example, why not use OpenBSD's /dev/arandom?
|
||||
|
||||
I don't trust ARC4. For example, recent cryptographic efforts
|
||||
indicate that you must throw away the first 512 bytes generated from
|
||||
the PRNG for it to be secure. I don't know whether OpenBSD do this.
|
||||
Further, I recall some eprint paper on RC4 security that didn't
|
||||
inspire confidence.
|
||||
|
||||
While I trust the random devices in OpenBSD more than
|
||||
Solaris/AIX/HPUX/etc, I think that since we need something better on
|
||||
Solaris/AIX/HPUX we'd might as well use it on OpenBSD or even Linux
|
||||
too.

|
||||
|
||||
I'm not sure this is a good idea. Users can't really be expected to
|
||||
understand this. Further, applications need many different kind of
|
||||
random data. Selecting the randomness level for each by the user will
|
||||
be too complicated.
|
||||
|
||||
I think it is better if the application decide, from its cryptographic
|
||||
requirement, what entropy quality it require, and call the proper API.
|
||||
Meeting the implied semantic properties should be the job for gnulib.

|
||||
|
||||
Agreed.
|
||||
|
||||
This may require some thinking before it is finalized. Is it ok to
|
||||
install the GC module as-is meanwhile? Then I can continue to add the
|
||||
stuff that GnuTLS need, and then come back to re-working the
|
||||
randomness module. That way, we have two different projects that use
|
||||
the code. GnuTLS includes the same randomness code that was in GNU
|
||||
SASL and that is in the current gc module. I feel much more
|
||||
comfortable working in small steps at a time, rather then working on
|
||||
this for a long time in gnulib and only later integrate the stuff in
|
||||
GnuTLS.
