Certificates and Inherit Trust

On the Octopus Blog, we’ve delved quite a bit into the vulnerabilities of contemporary encryption standards. The system of Public Key Infrastructure (PKI) which forms the basis of most of the worlds authentication platforms, while presenting a powerful, easy to use encryption model, still left several holes through which attackers can breach networks and steal identities. Perhaps the single biggest problem [...]

Stopping Man-In-The-Middle Attacks with Cryptography

Man-in-the-middle (MITM) attacks – where an attacker secretly relays and possibly alters the communication between two parties who believe they are directly communicating with each other – are a very real threat, especially when it comes to authentication. Various solutions have been put forward to prevent, or at least manage, this threat. These have met varying levels of success, although it [...]

Zero Knowledge Proof – What Peggy Knows About Victor

Zero knowledge proof authentication is the basis of modern-age authentication. It allows for the highest level of security, by ensuring passwords, transactions and conversations don’t get compromised when transferred over an unsecured connection. In this article we will look at zero knowledge proof to understand the need for it, how it works, and where it’s being utilized to verify parties today. [...]
