* U S A G E
|
||||
* ===========
|
||||
*
|
||||
* For DES or Triple-DES encryption/decryption you must initialize a proper
|
||||
* encryption context with a key.
|
||||
*
|
||||
* A DES key is 64bit wide but only 56bits of the key are used. The remaining
|
||||
* bits are parity bits and they will _not_ checked in this implementation, but
|
||||
* simply ignored.
|
||||
*
|
||||
* For Triple-DES you could use either two 64bit keys or three 64bit keys.
|
||||
* The parity bits will _not_ checked, too.
|
||||
*
|
||||
* After initializing a context with a key you could use this context to
|
||||
* encrypt or decrypt data in 64bit blocks in Electronic Codebook Mode.
|
||||
*
|
||||
* DES Example
|
||||
* -----------
|
||||
* unsigned char key[8];
|
||||
* unsigned char plaintext[8];
|
||||
* unsigned char ciphertext[8];
|
||||
* unsigned char recoverd[8];
|
||||
* gl_des_ctx context;
|
||||
*
|
||||
* // Fill 'key' and 'plaintext' with some data
|
||||
* ....
|
||||
*
|
||||
* // Set up the DES encryption context
|
||||
* gl_des_setkey(&context, key);
|
||||
*
|
||||
* // Encrypt the plaintext
|
||||
* des_ecb_encrypt(&context, plaintext, ciphertext);
|
||||
*
|
||||
* // To recover the orginal plaintext from ciphertext use:
|
||||
* des_ecb_decrypt(&context, ciphertext, recoverd);
|
||||
*
|
||||
*
|
||||
* Triple-DES Example
|
||||
* ------------------
|
||||
* unsigned char key1[8];
|
||||
* unsigned char key2[8];
|
||||
* unsigned char key3[8];
|
||||
* unsigned char plaintext[8];
|
||||
* unsigned char ciphertext[8];
|
||||
* unsigned char recoverd[8];
|
||||
* gl_3des_ctx context;
|
||||
*
|
||||
* // If you would like to use two 64bit keys, fill 'key1' and'key2'
|
||||
* // then setup the encryption context:
|
||||
* gl_3des_set2keys(&context, key1, key2);
|
||||
*
|
||||
* // To use three 64bit keys with Triple-DES use:
|
||||
* gl_3des_set3keys(&context, key1, key2, key3);
|
||||
*
|
||||
* // Encrypting plaintext with Triple-DES
|
||||
* gl_3des_ecb_encrypt(&context, plaintext, ciphertext);
|
||||
*
|
||||
* // Decrypting ciphertext to recover the plaintext with Triple-DES
|
||||
* gl_3des_ecb_decrypt(&context, ciphertext, recoverd);

*
|

* PBKDF2 applies a pseudorandom function (see Appendix B.1 for an
|

* example) to derive keys. The length of the derived key is essentially
|
||||
* unbounded. (However, the maximum effective search space for the
|
||||
* derived key may be limited by the structure of the underlying
|
||||
* pseudorandom function. See Appendix B.1 for further discussion.)
|

* PBKDF2 is recommended for new applications.
|
||||
*
|
||||
* PBKDF2 (P, S, c, dkLen)
|
||||
*
|
||||
* Options: PRF underlying pseudorandom function (hLen
|
||||
* denotes the length in octets of the
|
||||
* pseudorandom function output)
|
||||
*
|
||||
* Input: P password, an octet string (ASCII or UTF-8)
|
||||
* S salt, an octet string
|
||||
* c iteration count, a positive integer
|
||||
* dkLen intended length in octets of the derived
|
||||
* key, a positive integer, at most
|

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.
|
||||
|
||||
Thanks,

Compute q* :

q* := floor((r[j+n]*beta+r[j+n-1])/b[n-1]).

r[j+n]*beta+r[j+n-1] - q* * b[n-1] >= beta, i.e. c2 >= beta^2,

[r[n+j],...,r[j]] := [r[n+j],...,r[j]] - q* * [b[n-1],...,b[0]].

hence: u:=0, for i:=0 to n-1 do

u := u + q* * b[i],

r[j+i]:=r[j+i]-(u mod beta) (+ beta, if carry),

u:=u div beta (+ 1, if carry in subtraction)

r[n+j]:=r[n+j]-u.
|

{Since always u = (q* * [b[i-1],...,b[0]] div beta^i) + 1
|

< q* + 1 <= beta,

the carry u does not overflow.}
|

If a negative carry occurs, put q* := q* - 1

and [r[n+j],...,r[j]] := [r[n+j],...,r[j]] + [0,b[n-1],...,b[0]].

Set q[j] := q*.

Normalise [q[m-n],..,q[0]]; this yields the quotient q.

Shift [r[n-1],...,r[0]] right by s bits and normalise; this yields the

rest r.

The room for q[j] can be allocated at the memory location of r[n+j].
|

Finally, round-to-even:

/* The size of memory objects is often computed through expressions of

type size_t. Example:

void* p = malloc (header_size + n * element_size).
|

These computations can lead to overflow. When this happens, malloc()

returns a piece of memory that is way too small, and the program then
|

crashes while attempting to fill the memory.
|

To avoid this, the functions and macros in this file check for overflow.

The convention is that SIZE_MAX represents overflow.
|

malloc (SIZE_MAX) is not guaranteed to fail -- think of a malloc
|
||||
implementation that uses mmap --, it's recommended to use size_overflow_p()
|
||||
or size_in_bounds_p() before invoking malloc().
|
||||
The example thus becomes:
|

size_t size = xsum (header_size, xtimes (n, element_size));

void *p = (size_in_bounds_p (size) ? malloc (size) : NULL);
