Data Encryption and Decryption Using RSA Algorithm in a Network Environment One of the principal challenges of resource sharing on data communication network is its security.

While a classical computer would take 300 trillion years or more to decrypt a 2,048-bit Rivest-Shamir-Adleman encryption, a quantum one could crack it in seconds, thanks to qubits.

The U.S. National Institute of Standards and Technology (NIST) has released the first three encryption standards designed to resist future cyberattacks based on quantum computing technology.
