Every online bank transfer, private message and Bitcoin transaction rests on the assumption that some math problems are ...

Abstract: Quantum key distribution (QKD) allows Alice and Bob to share a secret key with proven information-theoretic security. Composability-based security proofs for QKD ensure that using the ...

As quantum computing advances, it brings both opportunities and challenges to the field of cryptography. Quantum computers have the potential to break current encryption methods, which is why the ...

How would you react if you knew that all your constituents' information is now readable and available to the highest bidder? Since the proliferation of the Internet and digitization of government ...

The Cloud Controls Matrix (CCM) is a framework of controls (policies, procedures, and technical measures) that are essential for cloud computing security. It is created and updated by CSA and aligned ...

Abstract: Assuring the medicinal data is very important for protecting the patient’s privacy and their trust in the team. Prohibited access to confidential medicinal data gives rise to privacy ...

In the context of cryptography, a public key is an alphanumeric string that serves as an essential component of asymmetric encryption algorithms. It is typically derived from a private key, which must ...

The original version of this story appeared in Quanta Magazine. For thousands of years, if you wanted to send a secret message, there was basically one way to do it. You’d scramble the message using a ...

Reports began surfacing in October that Chinese researchers used a quantum computer to crack military-grade AES 256-bit encryption. Those reports turned out to be wrong, but that did little to dampen ...
