Abstract: Quantum computing is generally considered non-threatening to symmetric ciphers. Quantum attacks on symmetric ciphers require a thorough analysis of their internal structures, posing ...

The same secret (private) encryption key used by both sender and receiver. Contrast with asymmetric cipher, which uses a public and private key. See secret key cryptography. THIS DEFINITION IS FOR ...

Abstract: The Internet of Things (IoT) is a vital technology for connecting devices and systems, enabling smart decision-making, automation, and efficiency across industries. Its popularity continues ...

This report details a C++ benchmarking tool designed to measure and compare the performance of three symmetric block ciphers: AES, Camellia, and SM4. The implementation leverages the OpenSSL library's ...

This repository contains an educational implementation of a custom 64-bit symmetric block cipher. It was developed to explore and demonstrate the core principles of modern cryptography, including key ...

How does symmetric key encryption work with public-key encryption when securing a connection between browser and server? I know the Browser and server start off using asymmetric encryption then switch ...

Although most users don’t know it, their Web browser plays a key part in determining the strength of the ciphers used between their client and an HTTPS-protected Web site. Encryption ciphers used in ...

I had this idea. Might be a good idea, might be a terrible idea. I'm no expert on security, but I wonder if any systems have ever done this? Typically, historically, authentication databases have ...
