SG100 Delivering Security Since 1997 to the World For more than a decade Protego Information AB has delivered the SG100 unit to the world market. No other unit has been so through fully tested and examined by time and the market. The SG100 Security Generator could be considered the gold standard of TRNG devices. With more than 10 000 installations world wide the SG100 has proved it’s worth. If you want a 100% bullet proof and reliable solution withlow risk, you should choose the SG100 Security Generator as your True Random Number Generator. SG100 Security Generator is an easy to use, easy to integrate hardware random number generator that connects to a standard serial port. Complete with driver software for Windows and example programs in source. SG100 is the choice if you want to strengthen and enhance your encryption, statistics and simulation software. The SG100 was the first of our random number products, released in 1996. The SG100 is delivered with a driver for Microsoft Win32 (Microsoft Windows 95/98/XP and Windows NT (all versions/revisions). A source code application program is included for Windows, Solaris, and Linux. The source code application program is written in C to enable portabillity to other platforms. The device is connected to the computer through the 9-pin serial port. Power is taken from the port. Supports all bit rates up to 115,200 bit/s. Throughput is about 9.2 kBytes/s for the 115,200-bit/s rate. The output is processed using statistical and cryptographic methods, and passes any statistical test. Resistant to external electromagnetic fields and high resistance against power fluctuations.

Additional

Linux Driver
The included Linux driver is a source code that may be integrated with
an application. Random numbers are obtained by a fuction call. The Linux driver
compile on Windows, Linux, and Solaris. The Linux driver is easy to modify and
adopt to different architectures and application areas.

Solaris Random Number Server
We have an Intel 32 bit Solaris-8 driver, intended for more complex
situations. This driver run multiple SG100:s and distribute the random
numbers using a local network. The Solaris driver include a disk buffer.

Embedded Solution
The SG100 circuit may be licenced for an embedded solution.
See Embedded Systems for additional information.

Prices and Availability

The SG100 is available in two basic packages; Developer and Runtime.

Developer Package

One SG100 Generator.
Drivers/License for the Win32 platform (Microsoft Windows 95/98, Windows NT
and Windows 2000) in DLL format with C/C++ header file.
Demo Programs, compiled to EXE including C/C++ source, that open and use the driver DLLs.
Hardware Test Programs (EXE only) for the SG100 hardware.
The license right to use the drivers with SG100 Runtime.

Runtime Package

One SG100 Generator.
Drivers are not included in the Runtime Package. Customers should obtain
    an SG100 Developer Package, that include drivers.
Customers of the Developer Package may copy the Win32 driver
and use with SG100 runtime Packages.

Important Tech Note!

The current version of the SG100 do not work on some multi-function
chipsets for serial/parallel ports. These chipsets where common on Pentium II computers.

Statistical Tests

The simplest statistical test is to check if the SG100 random number strings has about the same number of ones and zeroes. A test program (N1_TEST.EXE, included in Developer Package) is written that counts bytes and bits. The output is given in absolute and relative frequency.

To make comparison easy the difference between a relative frequency of 50% and observed frequency is computed relative to the standard deviation. These values are seldom higher than three, for random output.

Note, that as the program outputs a large number of sigma values, it sometimes happens that a sigma value higher than three is found. This is normal for random strings. If in doubt, accuracy can be increased by counting a longer string.

If we, as an example, count 6,400,000 bytes and find 25,603,990 "one" bits then we have a relative frequency of 0.50007793 Sigma = 1.1 That is 50.008% one bits.

To increase accuracy we count 441,600,000 bytes. We find 1,766,378,269 "one" bits yielding a frequency of 0.49999385 ( Sigma = -0.7) That was very close to 50% "one" bits and 50% "zero" bits. Desperately we can read 1,651,200,000 bytes and count to 6,604,734,712 "one" bits and the frequency is 0.49999506 ( Sigma = -1.1).

pLab load test of the SG100

The pLAB Research Group of the Institut für Mathematik, Universität Salzburg has conducted a load test of the SG100™. The report contains commented simulation results for SG100™. Each page contains the plot of the truncated Kolmogorov-Smirnov-values and the according uppeirtail-probabilities for the Load Test'(LT).

Diehard

The SG100 also passes the Diehard test. The Diehard test, by George Marsaglia, consists of several statistical counts that should have a specified distribution if the input string is random. By comparing observed counts to a theoretical count we can see if a string is random or not.

For a sample of size 500: mean SG100.DAT using bits 6 to 29 1.942

Chisquare with 6 d.o.f. = 2.61 p-value= .143850

The observations above are to few to give high accuracy. This problem originates in that the Diehard program do not adjust the sample sizes to a larger test file.
