Jarno Lamsa 282db8e3f8 Protect get/put on secret data on AES-module 
When reading the input, buffer will be initialised with random data
and the reading will start from a random offset. When writing the data,
the output will be initialised with random data and the writing will start
from a random offset.

Arto Kinnunen dbf2b43ceb Add more variation to random delay countermeasure 
Add more variation to the random delay function by xor:ing two
variables. It is not enough to increment just a counter to create a
delay as it will be visible as uniform delay that can be easily
removed from the trace by analysis.
 2020-01-07 10:47:58 +02:00
Arto Kinnunen 0490485be5 Add random delay to enforce_volatile_reads

Arto Kinnunen 4c63b98e94 Add random delay function to platform_utils 
Add delay function to platform_utils. The function will delay
program execution by incrementing local variable randomised number of
times.

Jarno Lamsa 5aa4c07b85 Minor review fixes 2019-12-20 13:09:27 +02:00
Jarno Lamsa 015aa44b93 Make authmode volatile 
This is to enforce reading it from memory for the double
check to prevent compiler from optimising it away.
 2019-12-20 12:09:37 +02:00
Jarno Lamsa af60cd7698 Protect the peer_authenticated flag more 
Add more protection to the flag preventing attacker
possibly to glitch using faulty certificate.
 2019-12-20 10:50:33 +02:00
Jarno Lamsa 616fbe177c Increase hamming distance for authmode 
Prevent glitching mode by single bit flipping.
 2019-12-19 17:07:35 +02:00
Jarno Lamsa 8d09e5744c Increase hamming distance for session resume flag 
This is to prevent glitching a single bit for the resume flag.
 2019-12-19 17:07:35 +02:00
Jarno Lamsa 489dccd158 Adress review comments 2019-12-19 17:07:35 +02:00
Jarno Lamsa 88db2ae9a0 Use Platform fault when double check fails 2019-12-19 17:07:35 +02:00
Jarno Lamsa f5b6af01d3 Fix double check in entropy_gather_internal 
The double check was wrong way, glitching either check
could have compromised the flow there.
 2019-12-19 17:07:29 +02:00
Jarno Lamsa afff4d0679 Remove unused flag 2019-12-19 14:41:56 +02:00
Jarno Lamsa 06164057b3 Check that we have all the proper keys 
The proper keys should be set at the end of
the handshake, if not, fail the handshake.
 2019-12-19 14:40:36 +02:00
Jarno Lamsa e1621d4700 Check that the peer_authenticated flag 
Check that the peer has been authenticated in the end
of the handshake.
 2019-12-19 14:29:24 +02:00
Jarno Lamsa ba4730fe4c Protect setting of peer_authenticated flag 
Use flow counting and double checks when setting the flag.
Also protect the flow to prevent causing a glitch.
 2019-12-19 09:43:25 +02:00
Jarno Lamsa 4031a45019 Protect key_derivation_done flag 
The flag is used to track that the key derivation
has been done.
 2019-12-19 09:43:25 +02:00
Jarno Lamsa 67f0a1e833 Protect setting of premaster_generated flag 
The flag is used for tracking if the premaster has
been succesfully generated. Note that when resuming
a session, the flag should not be used when trying to
notice if all the key generation/derivation has been done.
 2019-12-19 09:43:19 +02:00
Jarno Lamsa 98801af26b Protect setting of hello_random flag 
The handshake flag tells when the handshake hello.random
is set and can be used later to decide if we have the correct
keys.
 2019-12-19 09:02:02 +02:00
Jarno Lamsa b57d7fd568 Add flags for protecting TLS state machine 
Flags are there to prevent skipping vital parts of the TLS
handshake.
 2019-12-19 09:01:54 +02:00
Jarno Lamsa 6122b59042 Address review comments 2019-12-19 07:56:10 +02:00
Jarno Lamsa 46afd5d8fa Fix CI issues 
Default flow assumes failure causes multiple issues with
compatibility tests when the return value is initialised
with error value in ssl_in_server_key_exchange_parse.
The function would need a significant change in structure for this.
