2048位的RSA目前应该还没有那么好破解。 --（需要20m个qubits才能破解2048位RSA） [Researchers] have shown how a quantum computer could do the calculation with just 20 million qubits. Indeed, they show that such a device would take just eight hours to complete the calculation. https://qubitreport.com/quantum-computing-cybersecurity-and- cryptography/2019/06/07/2048-bit-rsa-cracked-in-8-hours/

--(目前Google的量子计算机只有53位) Fortunately, it has only 53 qubits which the Shor’s Algorithm may take millions of qubits to crack the 2048-bit key! https://medium.com/@jonathan_hui/quantum-supremacy-google-sycamore-processor-6f30073a17fa

Design and Implementation of FROST - Digital Forensic Tools for the OpenStack Cloud Computing Platform

Unlike traditional acquisition tools, FROST works at the cloud management plane rather than interacting with the operating system inside the guest virtual machines, thereby requiring no trust in the guest machine.
