Answers to Questions (FAQ)
What is the Bit Reversal? (Definition)
Bit reversal (or bit order inversion) is an operation that reverses the sequence of bits in a binary word, integer, or message.
Example: A byte represented by 11010010 will have the bit reversal 01001011
How to encode using Bit Reversal?
To encode a message by reversing the order of its bits:
— Convert to binary: For text, use an encoding (ASCII, UTF-8) and then convert each byte to binary.
— Reverse the bit order: Take the binary sequence and read it from right to left.
Note: Reading can be done sequentially (all 8-bit bytes, or all at once, or according to a custom interval).
How to decode using Bit Reversal?
Decoding is identical to encoding.
Applying two encodings results in recovering the original message.
What are the variations of bit reversal?
Bit order reversal can be adapted or combined with other operations:
— Partial reversal: Invert only certain bits (e.g., the 4 least significant bits)
— Block reversal: Apply the reversal to segments of a fixed size (e.g., 16 bits, 32 bits)
— Conditional reversal: Invert based on a key, a mask, or the content to be reversed
