DiceLock 22.214.171.124 for Windows – DiceLockXTSIndexed storage sector base cipher architecture configuration selecting Twofish 256 block cipher and Random Test Suite with Frequency, Block Frequency, Cumulative Sum Forward, Longest Run Of Ones and Runs random number tests, using IncreaseBase0IndexModifier_6_0_0_1 by index key modifier, DefaultCryptoRandomStream bit data stream
DiceLockXTSIndexedFullBasedCheck is a C++ program to verify that DiceLockXTSIndexed class implementing one of DiceLock different architectures is working as expected.
DiceLockXTSIndexed class is the cryptographic architecture aimed to storage devices based on XTS operation mode (XEX-based tweaked-codebook mode with ciphertext stealing encryption algorithm) and providing same intrinsic characteristics of DiceLock cipher architecture.
DiceLockXTSIndexed class is the class that implements DiceLock architecture with the following characteristics:
– storage devide sector length is any value multiple of 128 bits bigger than 512 bits,
– base encryption cipher/decipher is a block cipher working with symmetric key,
– 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 DiceLockXTSIndexed architecture are:
– as base encryption cipher/decipher:
– 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.
Because DiceLockXTSIndexed class can work on full length plaintext length or sector based length, there are different alternatives for encryption/decryption, we have split DiceLockXTSIndexed class tests in two main C++ program tests:
– DiceLockXTSIndexedSectorBasedCheck C++ Source Code program applying DiceLockXTSIndexed encryption/decryption on sector base,, and
– DiceLockXTSIndexedFullBasedCheck C++ Source Code program applying DiceLockXTSIndexed encryption/decryption on full plaintext length basis,.
In this test we verify DiceLockXTSIndexedFullBasedCheck C++ Source Code program encryption/decryption on device storage sector base with the configuration shown below.
While performing internal software quality assurance we have verified that DiceLockXTSIndexedSectorBasedCheck in debug mode does not generate any memory leaks with any executed option.
Debug mode was run with the corresponding debugger and the C Run-Time Libraries (CRT) debug heap functions as well as with dump memory leak information function that can be obtained executing “_CrtDumpMemoryLeaks” statement before program ends execution.
In this test we have selected this DiceLock configuration:
DiceLock class: DiceLockXTSIndexed
Storage devide sector length in bytes = 512, 1024, 1536, 2048, 2560, 3072, 3584, 4096, 16384, 32768, (selected in a random basis),
Encryption block cipher: Twofish 256 block cipher
Random number test: Frequency
Random number test: Block Frequency
Random number test: Cumulative Sum Forward
Random number test: Longest Run of Ones
Random number test: Runs
All random number test significance level: Alpha = 0.001 (confidence level of 99.9%)
Symmetric key modifier class: IncreaseBase0IndexModifier_6_0_0_1 by index key modifier
Bit stream class: DefaultCryptoRandomStream bit data stream
DefaultCryptoRandomStream class makes use of default virtual memory where the system can move pages of physical memory to and from a paging file on disk (manipulation of physical memory by the system is completely transparent to applications).
At post bottom there are C++ Source Code links to all DiceLock cipher files being used to perform this configuration test.

In the following post you can find DiceLockXTSIndexedSectorBasedCheck C++ source code that has been executed where you can see how DiceLockXTSIndexed class can work with all different options:
And the result we’ve gotten is:

Original output log file from DiceLockXTSIndexedSectorBasedCheck execution:
From log file we can see that all randomized-encrypted text sequences have been correctly deciphered.
While DiceLockXTSIndexedSectorBasedCheck was executed a log file of reciphered (plaintext sequences being ciphered more than one time in order to get sequences at random) text sequences has been stored.
DiceLockXTSIndexedFullBasedCheck reciphers log file is composed of rows, and each row shows hexadecimal value for each byte of symmetric key and plaintext, plaintext length in bits, storage device sector length in bytes, data unit value, start block value within data unit, and number of reciphers executed with such plaintext and symmetric key.
Reciphers log file:
This output file will allow us to extract statistical information and to verify DiceLock cipher architecture execution between different operating system environments.
So, DiceLock cipher test and analysis can go on …
