2b45cf0dd1
Accept connections asynchronously.
2011-11-17 18:59:34 +00:00
27a3f6e497
Erase known copies of keys (unit tests ensure we don't end up using
...
zeroed keys).
2011-11-17 09:54:24 +00:00
66d973bcdd
Ignore expected IVs that arrive by the wrong transport.
...
This prevents an attacker from replaying connections to test whether a
transport endpoint has the same owner as an endpoint on another
transport (eg probing a Bluetooth device to see whether it has the
same owner as a given internet host).
2011-11-17 09:24:28 +00:00
13ebd369e2
The KDF was using CTR mode unsafely.
...
The data to be encrypted should go in the IV, with a blank
plaintext, so that the ciphertext is equal to the keystream.
Putting the data in the plaintext would have led to different keys
derived from the same source consisting of the same keystream XORed
with different guessable plaintexts. That would have been bad.

Keep the connection windows in memory.
2011-11-16 17:57:56 +00:00
f10512d787
Erase keys after using them. (Copies created by ciphers, etc, may
...
still exist.)
2011-11-16 16:22:35 +00:00
f6ae4734ce
Forward secrecy.
...
Each connection's keys are derived from a secret that is erased after
deriving the keys and the secret for the next connection.
2011-11-16 15:35:16 +00:00
d02a68edfc
Return a connection context for outgoing connections (the secret will
...
be included in this context in the near future).
2011-11-15 17:47:30 +00:00
fabdaf5957
Remove transport ID from connection context.
2011-11-15 17:32:31 +00:00
9220bb3426
Key derivation function based on NIST SP 800-108.
2011-11-15 17:19:11 +00:00
6a15c03e81
Store the incoming and outgoing secrets separately.
2011-11-15 16:07:14 +00:00
f41d48eb9f
Made secret keys erasable from memory.
2011-11-15 14:43:06 +00:00

Removed double-encryption of shared secrets.
2011-11-15 14:09:28 +00:00
6cdf68d6cb
Initialise all connection windows when a contact is added.
2011-11-15 13:45:57 +00:00
df054b1743
Store each connection window slot as a database row.
...
This is less memory-efficient but necessary for the coming forward
secrecy changes.
2011-11-15 13:08:20 +00:00
cf49a28c95
Replaced SHA-256 with SHAd-256 to prevent length extension attacks.
2011-11-15 11:11:31 +00:00
effa5c9d8e
Throw checked exception if concurrent attempts are made to remove a
...
contact.
2011-11-15 09:51:51 +00:00
6fd8493d3d
Singleton lists and singleton sets aren't equal, so use lists
...
consistently.
2011-11-15 09:42:21 +00:00
0da94879ef
Use aliases for shorter, clearer SQL.
2011-11-15 09:35:07 +00:00

Minor refactoring.
2011-11-14 22:14:52 +00:00
73aa7d14d7
Split transport identifiers into two: TransportId (globally unique)
...
and TransportIndex (locally unique).
This is the first step towards forward secrecy. Also removed the
Writable interface and unnecessary user-defined types, moved various
constants to ProtocolConstants and renamed some classes.
2011-11-14 21:40:05 +00:00
7d09102c4d

...
(untested).
