Crypto-Risk: Your Data Security Blind Spot

For many years — almost since the beginning of secure internet communications — data security professionals have had to face the challenge of using certificates, the mechanism that forms the basis of Transport Layer Security (TLS) communications. Certificates facilitate secure connections to websites (represented by the “s” in “https”

How safe browsing fails to protect user privacy

Recently, security researchers discovered that Apple was sending safe browsing data to Tencent for all Chinese users. This revelation has brought the underlying security and privacy guarantees of the safe browsing protocol under increased scrutiny. In particular, safe browsing claims to protect users by providing them with something called k-anonymity. In th

Multi-Party Computation on Machine Learning

During my internship this summer, I built a multi-party computation (MPC) tool that implements a 3-party computation protocol for perceptron and support vector machine (SVM) algorithms. MPC enables multiple parties to perform analyses on private datasets without sharing them with each other. I developed a technique that lets three parties obtain the resul

Five years later, Heartbleed vulnerability still unpatched

The Heartbleed vulnerability was introduced into the OpenSSL crypto library in 2012. It was discovered and fixed in 2014, yet today—five years later—there are still unpatched systems.  This article will provide IT teams with the necessary information to decide whether or not to apply the Heartbleed vulnerability fix. However, we caution: The latter c

Better Encrypted Group Chat

Broadly, an end-to-end encrypted messaging protocol is one that ensures that only the participants in a conversation, and no intermediate servers, routers, or relay systems, can read and write messages. An end-to-end encrypted group messaging protocol is one that ensures this for all participants in a conversation of three or more people. End-to-end encrypte
