DiceLock 8.0.0.1 for Windows – DiceLockXTSIndexed storage sector base cipher architecture configuration selecting Twofish 192 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, PhysicalCryptoRandomStream 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:

  • any of following block ciphers:
      AES (Advanced Encryption Standard) with 128, 192 or 256 key bits,
      Camellia with 128, 192 or 256 key bits,
      Serpent with 128, 192 or 256 key bits,
      Twofish with 128, 192 or 256 key bits, or
  • – 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 192 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: PhysicalCryptoRandomStream bit data stream

    PhysicalCryptoRandomStream class makes use of AWE (Address Windowing Extensions) that uses physical nonpaged memory, so memory is not swapped to hard disk.
    In order to use PhysicalCryptoRandomStream class, which works with AWE it requires that “Lock Pages In Memory” Windows security setting policy permission must be granted in “Local Policy Settings” to the account executing the program, and in some versions the program must have “Run this program as an administrator” “Privilege Level” option checked.

    At post bottom there are C++ Source Code links to all DiceLock cipher files being used to perform this configuration test.

    Execution call has been:

    DiceLockXTSIndexedSectorBasedCheck A01 DiceLock-8-0-0-1-DiceLockXTSIndexed-Sector-Twofish-192-Frequency-Block-Frequency-CuSum-Forward-Longest-Run-Of-Ones-Runs-Incr-Base0-Index-Physical-memory.log

    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:

    DiceLockXTSIndexedSectorBasedCheck C++ Source Code program

    And the result we’ve gotten is:

    Verified:
    ---------
    DiceLock-8-0-0-1-DiceLockXTSIndexed-Sector-Twofish-192-Frequency-Block-Frequency-CuSum-Forward-Longest-Run-Of-Ones-Runs-Incr-Base0-Index-Physical-memory.log
    
    Number of streams tested: 62500
    
    From length of shorter stream tested in bits: 8
    Up to length of larger stream tested in bits: 500000
    
    
    Number of correct streams deciphered: 62500
    Number of incorrect streams deciphered: 0
    Incorrect deciphered streams = 0 ==> ---OK---
    
    Total encrypted streams with at least one sector being reciphered: 4267
    Maximum number of reciphers performed over one stream being reciphered: 5
    
    File with reciphered stream data:
    DiceLock-8-0-0-1-DiceLockXTSIndexed-Sector-Twofish-192-Frequency-Block-Frequency-CuSum-Forward-Longest-Run-Of-Ones-Runs-Incr-Base0-Index-Physical-memory.log.reciphered
    
    

    Original output log file from DiceLockXTSIndexedSectorBasedCheck execution:


    DiceLock-8-0-0-1-DiceLockXTSIndexed-Sector-Twofish-192-Frequency-Block-Frequency-CuSum-Forward-Longest-Run-Of-Ones-Runs-Incr-Base0-Index-Physical-memory.log

    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:


    DiceLock-8-0-0-1-DiceLockXTSIndexed-Sector-Twofish-192-Frequency-Block-Frequency-CuSum-Forward-Longest-Run-Of-Ones-Runs-Incr-Base0-Index-Physical-memory.log.reciphered

    This output file will allow us to extract statistical information and to verify DiceLock cipher architecture execution between different operating system environments.
