Read More In a vehicle-to-vehicle communication network utilizing PKI security methods to protect communications and in which the PKI encryption utilizes a Certificate Authority having both a private key and a publicly distributed key, a method for allocating multiple certificates for each vehicle which are assigned to each vehicle in the communication network. The method includes the step of assigning a unique secret key k to each vehicle in the communication network. The Certificate Authority then creates a plurality of public key and private key encryption pairs for each vehicle and each encryption pair is associated with an index i. A plurality of certificates are then created with one certificate for each value of the index. A revocation list comprising the secret keys is maintained by the Certificate Authority so that all encryption pairs assigned to a particular vehicle may be revoked by the secret key k corresponding to that vehicle.

Read More Dr. Paul Selvin from the University of IL has developed a streamlined process for creating coverslips with built-in, nanoscale fiduciary markers using thermal NIL. Unlike 50‐100 nm fluorescent nanoparticles, these markers can be custom made to different sizes and shapes. Using this method, Dr. Selvin found that there is no resulting auto-fluorescence in the blue part of the spectrum (emission from 450 nm and farther red), allowing for more proteins to be tracked simultaneously, a major advantage in the field. Additionally, the coverslip is stable enough to culture primary neuronal cells for over 2 weeks, while other micropatterned coverslips would detach from the glass surface during that amount of time.

Read More The emergence of datacenters as single computer entities has made latency a critical consideration in designing datacenter networks. PCIe interconnect is known to be a latency bottleneck in communication networks as its overhead can contribute to up to 90% of the overall communication latency. PCIe is a standard motherboard interface, sending a packet over a conventional NIC requiring several PCIe and memory channel transactions. This data movement in the network software stacks consumes thousands of processor cycles, which ultimately prevent ultra-low latency networking. Researchers eliminate NIC-PCIe transactions and instead use the local memory channels between the memory and NIC, resulting in reduced latency and improved data center computer performance (figure 1). This finding is the basis for NetDIMM, which is a method for integrating a network interface chip with the memory module of a computer. Figure 1: State of the art network interface architectures vs. NetDIMM On average, NetDIMM improves per packet latency by 49.9% compared with a baseline network deploying PCIe NICs (figure 2). The NetDIMM architecture is located in the memory module and does not require any change to the processor architecture or memory subsystem. Figure 2: One-way network latency breakdown for packets of various sizes when using a PCIe NIC (left), an integrated NIC (middle), and NetDIMM (left). X-axis is not drawn to scale. Most recently, NetDIMM was presented at the 52nd IEEE/ACM International Symposium on Microarchitecture in Columbus, Ohio. The conference publication can be accessed here.
