While many essential cryptographic primitives have sound theoretical constructions and associated implementations, their security guarantees do not always hold in practice. We find that these security flaws do not usually exist in the libraries themselves, but instead in how developers use these libraries. We select the most popular cryptographic libraries(More)

In this paper we develop an optimal cache-oblivious data structure that solves the iterated predecessor problem. Given k static sorted length-n lists L1, L2,. .. , L k and a query value q, the iterated predecessor problem is to find the largest element in each list which is less than q. Our solution to this problem, called " range coalescing " , requires(More)
1 Introduction This report explores the design of Context, a concurrent text editor for a peer-to-peer network of users. Context is fault-tolerant and operational even with failed nodes and unstable networks, making this design ideal for collaborative work within groups. Our system allows users to simultaneously edit local copies of documents before(More)
