+  Using various quantum phenomena like superposition and entanglement to perform computation is known as quantum computing, and the machines that perform the same with ease are quantum computers. With each day, quantum computing’s rise is looking to manifest the stories of science fiction into hard-hitting reality. At the same time, the World Economic Forum cited that the rise of quantum computers might create widespread security threats by breaking the cryptography that fortifies the digital ecosystem. But the IBM Cloud promises to solve such potential disasters.

Since computing is getting a massive makeover from traditional to quantum systems, the data, network, and platform security needs to be duly revised to provide additional support and make the entire system flawless. With quantum-computers set to achieve previously impossible targets, refurbishing the idea and structure of security using IBM Cloud’s innovative approaches holds a significant promise for the future of computing.


+  The systems running currently depend primarily on public-key cryptography. It is the primary source of problems that will initiate when large-scale quantum-based computers are universally operational. The quantum-computers function in a realm that will negate such public-key cryptography. As a result, security will be compromised, and there will be large-scale threats of data loss and other significant concerns.

+  IBM Cloud has further walked the mile and created a customized ingress controller for its Kubernetes deployments and a customized proxy router for IBM Cloud-managed OpenShift. This step is taken by IBM Cloud to enable the applications with QSC-protected access to IBM Cloud’s clusters. IBM Cloud has developed these solutions keeping in mind the requirements of the clients. The QSC-protected TLS session key establishment will hugely benefit such clients, and thus, they can easily access these clusters. Their application logic would not require any code change for further security provisions.

+ The custom ingress controllers and routers feature terminating TLSv1.3 connections for QSC-enabled applications and complete backward compatibility for non-QSC functions. The above approach has opened the gates for network connections to employ QSC KEM algorithms for session key establishment and the further possibilities of using a hybrid-QSC session key establishment. It is a unique way to prepare for the staged transition to QSC operation that will take over in the future.
