Prerequisite : RSA Algorithm
Why RSA decryption is slow ? RSA decryption is slower than encryption because while doing decryption, private key parameter ” d ” is necessarily large. Moreover the parameters – ” p and q ” are two very large Prime Number...

Chinese remainder theorem - Wikipedia
The Chinese remainder theorem has been used to construct a Gödel numbering for sequences, which is involved in the proof of Gödel's incompleteness theorems.
The prime-factor FFT algorithm (also called Good-Thomas algorithm) uses the Chinese remainder theorem for reducing the computation of a fast Fourier transform of size to the computation of two fast Fourier transforms of smaller sizes and (providing that and are coprime).Wikipedia · Text under CC-BY-SA licensehomomorphic encryption - Chinese Remainder Theorem and RSA ...
