DiceLockIndexedCheck is a C++ program to verify that DiceLockIndexed class implementing one of DiceLock different architectures is working as expected.
DiceLockIndexed class is the class that implements DiceLock architecture with the following characteristics:
– base encryption cipher/decipher is any symmetric cipher (stream cipher or block cipher operation mode) working with just symmetric key, no initialization vector (IV) is used,
– ciphered index pointing symmetric key modification plus ciphertext is checked for random number test properties,
– any function that is able to change original symmetric key with new values generating index pointing out such modification,
– bit random number tests that can verify that encrypted ciphertext is at random.
Current algorithm classes that can be used with DiceLockIndexed architecture are:
– stream cipher: ARC4 and ARC4_Discarding (discarding initial bits),
– symmetric key changers: IncreaseBase0IndexModifier_6_0_0_1 and DecreaseBase0IndexModifier_6_0_0_1,
- random number tests: Frequency, Block Frequency, Cumulative Sum Forward, Cumulative Sum Reverse, Runs, Longest Run Of Ones, Rank, Universal, Approximate Entropy, Serial, Discrete Fourier Transform tests and random number test Suite with any or all previous enumerated random number tests.

DiceLock Security is a company that operates from the European Union.
As an European company, European Union legislation applies regarding export of some of our knowledge and products.
Export of dual use products is regulated in the European Community by COUNCIL REGULATION (EC) No 428/2009 of 5 May 2009 setting up a Community regime for the control of exports, transfer, brokering and transit of dual-use items.
DiceLock is an encryption architecture making use of symmetric cipher algorithms employing cipher keys in excess (bigger than) of 56 bits, thus control maybe applicable to some of our products.
COUNCIL REGULATION (EC) No 428/2009 states in CATEGORY 5, PART 2 that “The control status of “information security” equipment, “software”, systems, application specific “electronicassemblies”, modules, integrated circuits, components or functions is determined in Category 5, Part 2 even ifthey are components or “electronic assemblies” of other equipment.
5A2 Systems, Equipment and Components
5A002 “Information security” systems, equipment and components therefor, as follows:
a. Systems, equipment, application specific “electronic assemblies”, modules and integrated circuits for “information security”, as follows and other specially designed components therefor:
1. Designed or modified to use “cryptography” employing digital techniques performing any cryptographic function other than authentication or digital signature and having any of the following:
a. A “symmetric algorithm” employing a key length in excess of 56 bits;
5D002 “Software” as follows:
a. “Software” specially designed or modified for the “development”, “production” or “use” of equipment specified in 5A002 or “software” specified in 5D002.c.;
c. Specific “software”, as follows:
1. “Software” having the characteristics, or performing or simulating the functions of the equipment,specified in 5A002;
2. “Software” to certify “software” specified in 5D002.c.1.
While we are studying and clarifying the European regulation as well as national laws, access to some descriptive and functional specifications as well as the software implementations of DiceLock or any of its components that can be affected by the current regulation is only allowed to detected member countries.
