Understanding Modulo Operations in Cryptography

What is the main purpose of using modulo operations in cryptography?

• To encrypt messages

• To convert integers to a specific range

• To perform addition

• To multiply numbers

In the formula n = qm + r, what does 'r' represent?

• The modulo

• The quotient

• The original number

• The remainder

How do you find the remainder when converting a positive integer using modulo?

• Subtract the mod from the integer

• Multiply the integer by the mod

• Add the integer to the mod

• Divide the integer by the mod and take the remainder

What is the result of converting 27 using Mod 6?

• 1

• 4

• 3

• 2

If a positive integer is less than the mod, what should you do?

• Multiply it by the mod

• Convert it to zero

• Subtract the integer from the mod

• No conversion is needed

What is the remainder when 51 is divided by 10?

• 10

• 5

• 1

• 0

In the example of converting 3 using Mod 4, what is the result?

• 0

• 1

• 3

• 2

What is the first step in converting a positive integer using modulo?

• Multiply the integer by the mod

• Divide the integer by the mod

• Add the integer to the mod

• Subtract the mod from the integer

What is the significance of the formula n = qm + r in modulo operations?

• It is a method for subtraction
