Bartlet?left a large residuary estate to the Board of Management for building, equipping and maintaining a Convalescent Home for the benefit only of patients from the hospital.

In the following article Sir Alfred describes the innovation, and the reasons for it. | I T will be seen from the accompanying photograph that the heads of the children are placed a...

The proof-assistant Yarrow

Yarrow is an interactive proof assistant based on the theory of Pure Type Systems, a family of typed lambda calculi. Yarrow has been designed as a flexible environment for experimentation with various typed lambda calculi. It offers both graphical and textual interfaces. It has been coded entirely in Haskell, making use of the Fudget library for the graphical interface. In this paper we concent...

Yarrow-160: Notes on the Design and Analysis of the Yarrow Cryptographic Pseudorandom Number Generator

We describe the design of Yarrow, a family of cryptographic pseudo-random number generators (PRNG). We describe the concept of a PRNG as a separate cryptographic primitive, and the design principles used to develop Yarrow. We then discuss the ways that PRNGs can fail in practice, which motivates our discussion of the components of Yarrow and how they make Yarrow secure. Next, we define a specif...
