2 v 1 8 A pr 1 99 8 A LIGHTWEIGHT UNIVERSE ?
How much matter is there in the universe? Does the universe have the critical density needed to stop its expansion, or is the universe underweight and destined to expand forever? We show that several independent measures, especially those utilizing the largest bound systems known-clusters of galaxies-all indicate that the mass-density of the universe is insufficient to halt the expansion. A pro...

متن کاملTouchstone { a Lightweight Processor Benchmark Touchstone { a Lightweight Processor Benchmark
Benchmarks are valuable for comparing processor performance. However, porting and running processor benchmarks on new platforms can be di cult. Touchstone, a simple addition benchmark, is designed to overcome portability problems, while retaining performance measurement accuracy. In this paper, we present experimental results that show Touchstone correlates strongly with processor performance u...
متن کاملA Lightweight Opportunistic Tunneling
We present LOT, a lightweight ‘plug and play’ secure tunneling protocol deployed at network gateways. Two communicating gateways, A and B, running LOT would automatically detect each other and establish an efficient tunnel, securing communication between them. LOT tunnels allow A to discard spoofed packets that specify source addresses in B’s network and vice-versa. This helps to mitigate many ...
متن کاملA Lightweight Hash Function
In this paper, to match a lightweight digital signing scheme of which the length of modulus is between 80 and 160 bits, a lightweight hash function called JUNA is proposed. It is based on the intractabilities MPP and ASPP, and regards a short message or a message digest as an input which is treated as only one block. The JUNA hash contains two algorithms: an initialization algorithm and a compr...
