Available Power Traces Tables

Tables Description

The power consumption traces available for the DPA contest, are stored in a public PostgreSQL database. These traces are regrouped by acquisition campaign, where each campaign is stored in a distinct table. The tables entries contain the following fields:

index: a unique identifier for a trace.
message: the clear message ciphered during the measurement.
key: the key used to cipher the message (the one your algorithm has to guess, so you can check if it worked successfully).
cryptogram: the result of the clear message's DES encipherment.
date: the date and time at which the measure has been done.
filename: the original filename used to store the trace.
filecontent: the properly trace data stored in an Agilent `.bin' format, a parser of which is provided in the reference implementation. Agilent distributes a documentation for the format and an example C programme that turns the `.bin' into a `.csv'.

Some tables of the database are accessible by a PostgreSQL client, or by your application using the PostgreSQL libpq library with the following informations:

hostname: dpa.enst.fr
username: guest
password: guest
database: production_traces
tablename: <See Below>

The publicly available tables are described below. They correspond to the three leakage curves discussed at FDTC'08, in slides 21-24 of this presentation.

Table name	`secmatv1_2006_04_0809`	`secmatv3_20070924_des`	`secmatv3_20071219_des`
Traces count	81,089	81,569	67,753
Description	Power consumption traces of the unprotected DES crypto-processor on the SecmatV1 SoC in ASIC. The measures have been done during a temporal window containing the 16 nominal DES rounds. These measurements have to be used for the contest.	Power consumption traces of the unprotected DES crypto-processor in the SecmatV3 SoC in ASIC. The measures have been done during a temporal window containing the 16 nominal DES rounds.	Power consumption traces of the unprotected DES crypto-processor on the SecmatV3 SoC in FPGA (Altera Stratix). The measures have been done during a temporal window containing the 16 nominal DES rounds.
Average trace
Differential trace for the first round transition of register `LR`

Sample Sessions

If you wish to interactively browse the database, you can use either a graphical or a command line client. We provide with two sample sessions using the psql command line client and the pgAdminIII graphical client.

1. With a Command Line Client, such as psql

$ psql -d production_traces -X -h dpa.enst.fr -U guest -W
Password for user guest:

type guest and ENTER. You are now connected to the database server:

Welcome to psql 8.1.11, the PostgreSQL interactive terminal.

Type:  \copyright for distribution terms
       \h for help with SQL commands
       \? for help with psql commands
       \g or terminate with semicolon to execute query
       \q to quit

SSL connection (cipher: DHE-RSA-AES256-SHA, bits: 256)

production_traces=>

Standard SQL requests or PostgreSQL commands can be typed at the production_traces=> prompt. For instance, we can ask for a description of the contest table secmatv1_2006_04_0809 with the command \d:

production_traces=> \d secmatv1_2006_04_0809
   Table "public.secmatv1_2006_04_0809"
   Column    |            Type             
-------------+-----------------------------
 index       | integer                     
 message     | text                        
 key         | text                        
 cryptogram  | text                        
 date        | timestamp without time zone 
 filename    | text                        
 filecontent | bytea

As mentioned earlier, the first fields are meta-information about the power trace, that is saved as a byte-array in the field filecontent. The key is the same for all traces. For instance, use this command to get an idea of the table contents:

production_traces=> SELECT message, key, cryptogram FROM secmatv1_2006_04_0809 LIMIT 10;
     message      |       key        |    cryptogram

2. With a Graphical Client, such as pgAdminIII

The same operations are illustrated with the GUI-based client pgAdminIII under Windows:

Login:
Getting the description of the contest table:
Requesting data from the contest table:

3. Dumping the Contest Database in a Directory

To retrieve the table as as many files as the contest table entries, use a script such as export_table.py.

To download directly the zip'ed campaigns of measurement, use those links (warning: each file is about one gigabyte large):

secmatv1_2006_04_0809.zip (4 Gbytes, in 4 parts: part0, part1, part2, part3)
secmatv3_20070924_des.zip (1 Gbyte, in 1 part)
secmatv3_20071219_des.zip (6 Gbytes, in 6 parts: part0, part1, part2, part3, part4, part5)

In order to verify the integrity of those files after download, use the following commands: md5sum.
