A newly proposed Double Latch Pre-charge Sense Amplifier (DLPSA) is introduced in the embedded non- volatile memory design for the wireless application, especially for smart cards with wireless & contactless feature, e.g., bank cards (wireless credit cards). This DLPSA has been implemented in both SMIC 0.18im and 0.13im process of ROM IPs. Comparing with the conventional sense amplifier, DLPSA...
Mobile nodes must authenticate themselves in order to use network services. When mobile nodes roam into a new cell, they must re-authenticate to the new layer 2 and 3 devices. This re-authentication process can take as long as two seconds, which is unacceptable for applications such as voice over IP. In this article we present several recently developed authentication protocols that can reduce the...
Technological advances in sensing, computation, storage, and communications will turn the near-ubiquitous mobile phone into a global mobile sensing device. People-centric sensing will help drive this trend by enabling a different way to sense, learn, visualize, and share information about ourselves, friends, communities, the way we live, and the world we live in. It juxtaposes the traditional view...
