DiceLock 188.8.131.52 for Windows – DiceLockDigested cipher architecture configuration selecting ARC4 (Alleged RC4) stream cipher, Sha 1 hash digest algorithm and Random Test Suite with Frequency, Block Frequency, Cumulative Sum Forward, Longest Run Of Ones and Runs random number tests, using IncreaseKeyModifier_6_0_0_1 key modifier, DefaultCryptoRandomStream bit data stream
DiceLockDigestedCheck is a C++ program to verify that DiceLockDigested class implementing one of DiceLock different architectures is working as expected.
DiceLockDigested 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,
– any hash digest algorithm is used to generate message hash digest from plaintext to be encrypted,
– ciphertext plus ciphered hash digest of plaintext is checked for random number test properties,
– any function that is able to change original symmetric key with new values,
– bit random number tests that can verify that encrypted ciphertext is at random.
Current algorithm classes that can be used with DiceLockDigested architecture are:
– stream cipher: ARC4 and ARC4_Discarding (discarding initial bits),
– hash digest algorithms: Sha 1, Sha 224, Sha 256, Sha 384, Sha 512, Ripemd 128, Ripemd 160, Ripemd 256, Ripemd 320, Md 2, Md 4 and Md5,
– symmetric key changers: IncreaseKeyModifier_6_0_0_1 and DecreaseKeyModifier_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.
While performing internal software quality assurance we have verified that DiceLockDigestedCheck 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: DiceLockDigested
Encryption stream cipher: ARC4 (Alleged RC4) stream cipher
Hash algorithm: Sha 1 hash digest algorithm
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: IncreaseKeyModifier_6_0_0_1 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.
Execution call has been:

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

Original output log file from DiceLockDigestedCheck execution:
From log file we can see that all randomized-encrypted text sequences have been correctly deciphered.
While DiceLockDigestedCheck 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.
DiceLockDigestedCheck 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 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 …
