We present Freeze & Crypt, a framework for main memory encryption. Our goal is to protect sensitive main memory on modern devices against memory attacks, such as via coldboot, DMA, or JTAG. This goal is of special significance when it comes to protec

While memory corruption bugs stemming from the use of unsafe programming languages are an old and well-researched problem, the resulting vulnerabilities still dominate real-world exploitation today. Various mitigations have been proposed to alleviate

AMD SEV is a hardware extension for main memory encryption on multi-tenant systems. SEV uses an on-chip coprocessor, the AMD Secure Processor, to transparently encrypt virtual machine memory with individual, ephemeral keys never leaving the coprocess

AMD SEV is a hardware feature designed for the secure encryption of virtual machines. SEV aims to protect virtual machine memory not only from other malicious guests and physical attackers, but also from a possibly malicious hypervisor. This relieves

Manipulations of return addresses on the stack are the basis for a variety of attacks on programs written in memory unsafe languages. Dual stack schemes for protecting return addresses promise an efficient and effective defense against such attacks.

Attacks on memory, revealing secrets, for example, via DMA or cold boot, are a long known problem. In this paper, we present TransCrypt, a concept for transparent and guest-agnostic, dynamic kernel and user main memory encryption using a custom minim

Keys for symmetric cryptography are usually stored in RAM and therefore susceptible to various attacks, ranging from simple buffer overflows to leaks via cold boot, DMA or side channels. A common approach to mitigate such attacks is to move the keys

In this paper, we present a novel secure architecture for OS-level virtualization on mobile devices. OS-level virtualization allows to simultaneously operate multiple userland OS instances on one physical device. Compared to previous approaches, our
