Independent Report on E-voting in Estonia. There were staggering gaps in procedural and operational security.

Widespread Weak Keys in Network Devices. We performed a large-scale study of RSA and DSA cryptographic keys in use on the Internet and discovered that significant numbers of keys are insecure due to insufficient randomness. We were able to remotely obtain the DSA private keys for 1. In experiments with several popular open-source software components.

ZMap is an open-source network scanner that enables researchers to easily perform Internet-wide network studies. With a single machine and a well provisioned network uplink, ZMap is capable of performing a complete scan of the IPv4 address space in under 5 minutes, approaching the theoretical limit of ten gigabit Ethernet. Check out our Getting Started Guide. Or go and Download ZMap. PhD Candidate, University of Michigan.

Is a popular cryptographic algorithm that allows Internet protocols to agree on a shared key and negotiate a secure connection. It is fundamental to many protocols including HTTPS, SSH, IPsec, SMTPS, and protocols that rely on TLS. Logjam attack against the TLS protocol. Ciphers, and affects all modern web browsers.
