One of the principal challenges of resource sharing on data communication network is its security. This is premised on the fact that once there is connectivity between computers sharing some resources ...

Hot on the heels of Diffie-Hellman upending the cryptography applecart in 1976 came three more crypto newcomers that further revolutionized the field: Ron Rivest, Adi Shamir, and Leonard Adleman. The ...

Encryption, the transformation of data into a form that prevents anyone unauthorized from understanding that data, is a fundamental technology that enables online commerce, secure communication, and ...

Before delving into which key exchange algorithm is more secure or "better," let me start by explaining the differences between the Diffie-Hellman vs. RSA algorithms. Diffie-Hellman is a key exchange ...

Encryption algorithms can be intimidating to approach, what’s with all the math involved. However, once you start digging into them, you can break the math apart into smaller steps, and get a feel of ...

A couple of days ago on The Conversation, I set myself up with a task: to defend the usefulness of so-called “useless” maths. Today, that defence continues, with a look at the RSA algorithm. I ...

Understand the crypto concepts behind the modern internet security infrastructure, from digital signatures and transport layer security to blockchains and Bitcoin. Cryptography grows ever more ...

A research paper that claimed a quantum breakthrough that could "challenge RSA-2048" encryption received significant attention in the past week, followed by significant criticism as experts weighed in ...
