Technical Perspective: The Power of Joint Multiuser Beamforming

Having multiple Wi-Fi Access Points with an overlapping coverage area operating on the same frequency may not be a problem anymore.

JMB
From Communications of the ACM

JMB: Scaling Wireless Capacity with User Demands

JMB, a joint multiuser beamforming system, enables independent access points (APs) to beamform their signals and communicate with their clients on the same channel...

From Communications of the ACM

Technical Perspective: The Interplay of Neuroscience and Cryptography

An ideal scheme for password storage would enable a password with more than 20 bits of randomness to be input and output from the brain of a human being who is...

Neuroscience Meets Cryptography
From Communications of the ACM

Neuroscience Meets Cryptography: Crypto Primitives Secure Against Rubber Hose Attacks

We present a defense against coercion attacks using the concept of implicit learning from cognitive psychology. We use a carefully crafted computer game to allow...
