On the effectiveness of address-space randomization

by Hovav Shacham, Matthew Page, Ben Pfaff, Eu-jin Goh, Nagendra Modadugu, Dan Boneh - IN CCS ’04: PROCEEDINGS OF THE 11TH ACM CONFERENCE ON COMPUTER AND COMMUNICATIONS SECURITY , 2004

The idea is to introduce artificial diversity by randomizing the memory location of certain system components. This mechanism is available for both Linux (via PaX ASLR) and OpenBSD.

Single Address Space Or Private Address Spaces ?

by Jacques Mossi, Xavier Rousset De Pina - the Sixth European SIGOPS Workshop , 1994
"... this paper is organized as follows. In section 2 are discussed two different schemes for protection, both relying upon the capability concept. Section 3 gives an argument for the use of private data, and shows that they can be implemented at low cost. Section 4 outlines a proposal in which a shared ..."
Abstract - Add to MetaCart
single address space for persistent data coexists with private segments for temporary data. In conclusion, this proposal is compared to previous systems.

10 Address Space Relocation

by unknown authors
"... Our first attempts at virtualizing memory will be very simple, almost laughably so. Go ahead, laugh all you want; pretty soon it will be the OS laughing at you, when things get quite a bit more complex. Specifically, we will assume for now that the user’s address space must be placed contiguously in ..."

RTLinux with Address Spaces

by Frank Mehnert, Michael Hohmuth, Sebastian Schönberg, Hermann Härtig - In Proceedings of the Third Real-Time Linux Workshop , 2001
"... The combination of a real-time executive and an o#-the-shelf time-sharing operating system has the potential of providing both predictability and the comfort of a large application base. To isolate the real-time section from a significant class of faults in the (ever-growing) time-sharing operatin ..."
Abstract - Cited by 9 (3 self) - Add to MetaCart
-sharing operating system, address spaces can be used to encapsulate the time-sharing subsystem. However, in practice designers seldomly use address spaces for this purpose, fearing that extra cost induced thereby limits the system's predictability. To analyze this cost, we compared in detail two systems

Performance of Address-Space Multiplexing on the Pentium

by Volkmar Uhlig, Uwe Dannowski, Espen Skoglund, Andreas Haeberlen, Gernot Heiser , 2002
"... This paper presents an analysis of the performance potential and limitation of the so-called small-space scheme, where several logical address spaces are securely multiplexed onto a single hardware address space. This can be achieved on the IA-32 architecture by using the segment registers to reloca ..."

A Distributed Single Address-Space . . .

by Gernot Heiser, Kevin Elphinstone, Stephen Russell, Graham R. Hellestrand , 1993
"... Persistence has long been difficult to integrate into operating systems. The main problem is that pointers lose their meaning once they are taken out of their address-space. We present a distributed system which has a single address-space encompassing all virtual memory of every node in the system. ..."

Architectural Support for Single Address Space Operating Systems

by Eric J. Koldinger, Eric J. Koldinger, Jeffrey S. Chase, Jeffrey S. Chase, Susan J. Eggers, Susan J. Eggers , 1992
"... Recent microprocessor announcements show a trend toward wide-address computers: architectures that support 64 bits of virtual address space. Such architectures facilitate fundamentally new operating system organizations that promote efficient data sharing and cooperation, both between complex applic ..."

The Abstraction: Address Spaces

by unknown authors
"... In the early days, building computer systems was easy. Why, you ask? Because users didn’t expect much. It is those darned users with their expectations of “ease of use”, “high performance”, “reliability”, etc., that really have led to all these headaches. Next time you meet one of those computer use ..."
