Abstract: In this paper, we proposed a simplified version of the Grain-128 stream cipher and developed a corresponding quantum circuit. Leveraging Grover's algorithm, we demonstrate the ability to ...

Abstract: Secure Shell (SSH) is a robust cryptographic network protocol designed to establish a secure and encrypted connection over potentially insecure networks, which is typically used for remote ...

For most of Bitcoin’s history, the threat of quantum computers breaking its cryptography was a distant, theoretical worry, the kind of thing dismissed with “by the time that happens, we will have ...
