SSL is the de facto standard today for securing end-to-end transport on the Internet. While the protocol itself seems rather secure, there are a number of risks that lurk in its use, for example, in web banking. However, the adoption of password-based key-exchange protocols can overcome some of these problems. We propose the integration of such a protocol(More)
PANDA is a run-time package based on a very small operating system kernel which supports distributed applications written in C++. It provides powerful abstractions such as very efficient user-level threads, a uniform global address space, object and thread mobility, garbage collection, and persistent objects. The paper discusses the design rationales(More)
functionality would significantly extend smart card possibilities. However, until very recently, such promises have not been backed by real implementations; JavaCard existence has been limited to reference implementations—better known as simulations. However, JavaCard implementations now exist and the technology is beginning to live up to the hype. A(More)
In modern programming environments, the increasing variety of programming models cannot be satisfactorily matched by a single operating system interface. An interface adaptable to specific application needs requires a user-level realization of system services. The operating system kernel should be reduced to minimal functionality, not biased towards a(More)

There is now widespread agreement that the surface of Mars underwent some degree of fluvial modification , but there is not yet full understanding of its surface hydrological cycle and the nature of standing bodies of water, rivers, and precipitation that affected its surface. In this paper we explore Erythraea Fossa (31.5 W, 27.3 S), a graben adjacent to(More)
