What is the general formula for the Chinese remainder theorem?
Here is a more general form of the Chinese remainder theorem. x ≡ a1 mod m1, x ≡ a2 mod m2, , x ≡ ar mod mr, has a solution, and this solution is uniquely determined modulo m1m2 ···mr.
What is an example of a CRT in cryptography?
Cryptography: The CRT is used in several cryptographic systems to generate and verify digital signatures.
For example, the RSA cryptosystem uses CRT to speed up the decryption process.
It computes the ciphertext modulo of two different primes and then combines the two results using the CRT.Today, the CRT has applications in every area of mathematics.
In particular, it is used extensively in computer science.
For example, internet cryptography encodes numbers using mathematics that has its origins in the Chinese Remainder Theorem.
What is the Chinese remainder theorem with example?
For example, if we know that the remainder of n divided by 3 is 2, the remainder of n divided by 5 is 3, and the remainder of n divided by 7 is 2, then without knowing the value of n, we can determine that the remainder of n divided by 105 (the product of 3, 5, and 7) is 23.
