True Random Numbers on CD

---

If you need true random numbers only sporadically and the purchase of one of our Hardware True Random Number Generators is not adequate, an alternative is offered here: True Random Numbers on CD.

Fields of application for the ZRANDOM:

• Generation of code numbers or transaction numbers
• Encryption of data (e.g. for communication in the Internet)
• Digital signatures
• Direct use for Monte-Carlo simulations or generation of seed numbers
• Reference for pseudo-random number generators
• Numeric solution of mathematical problems
• Control/test of gambling machines
• Creation of lottery numbers

Two CD versions are available.

Version 1:  Completely physically generated random bits

CD contains:

• 10 ... 35 binary random bit files*, each of 1E8 random bits (about 11.9 MByte)
• 10 ... 35 protocol files (with FIPS PUB140-1 test results) related to the binary files
• 1 Conversion program to create Integer or Real random numbers

Price:   5,- Euro per 1E8 (=100.000.000) random bits

Order name:   Z-CD-Phys
Please declare the number of binary files per CD (minimum = 10, maximum = 35)

Payment by PayPal (for 10 files):

Delivery within Germany (incl. shipping and VAT):  52 Euro

Delivery within the EU (incl. shipping and VAT):  55 Euro

Delivery outside of the EU (incl. shipping and VAT):  59 Euro

Version 2:  Semi-physically generated random bits (XOR mode)

CD contains:

• 35 binary random bit files*, each of 1E8 random bits (about 11.9 MByte)
• 35 protocol files (with FIPS PUB140-1 test results) related to the binary files

1 Conversion program to create Integer or Real random numbers

3.500.000.000 random bits per CD

Order name:   Z-CD-XOR

Payment by PayPal:

Delivery within Germany (incl. shipping and VAT):  52 Euro

Delivery within the EU (incl. shipping and VAT):  55 Euro

Delivery outside of the EU (incl. shipping and VAT):  59 Euro

Hints concerning the CDs:

• Only high-quality CD-Rs are used.
• After delivery of a CD all copies of the delivered files will be deleted.
• Only orders by Fax or mail (not email) can be accepted.
• Payment by Cash on Delivery* or Prepayment, for international companies and public authorities also by invoice.
• Delivery costs are: 2,- Euro in Germany / 5,- Euro in EU countries / 9,- Euro in non-EU countries.
• Additional costs for Cash on Delivery (*) are: 3,- Euro in Germany / 14,- Euro in EU countries / 18,- Euro in non-EU countries.
• Have a look at our delivery conditions.

In both modes absolutely non-deterministic, i.e. unpredictable random bit sequences are generated. During generation the most important statistical properties of the random bits are checked (by the FIPS PUB140-1 statistical tests). No bits which did not pass the tests are recorded. Here you will find a (short) example protocol file.

The conversion program is executable under Windows 95/98/NT/2000/XP. The number of random bits per decimal number can be varied from 1 to 32. Decimal random numbers (Integer or Real) are recorded in an ASCII file.

Binary random bit files created by our hardware generators pass the DIEHARD - TEST developed by George Marsaglia without any problems. DIEHARD contains 15 statistical random bit tests and can be regarded as an "acid test" for every random number generator. A lot of generators, like RAN2 from Numerical Recipes, don't pass this test.
