Secure deletion of data from magnetic and solid-state memory

With the use of increasingly sophisticated encryption systems, an attacker wishing to gain access to sensitive data is forced to look elsewhere for information. One avenue of attack is the recovery of supposedly erased data from magnetic media or random-access memory. This paper covers some of the methods available to recover erased data and presents schemes to make this recovery significantly more difficult.

Encrypting Virtual Memory
TLDR
The solution described in this paper uses swap encryption for processes in possession of confidential data that has been implemented for the UVM virtual memory system and its performance is acceptable.
On Secure Data Deletion
TLDR
Approaches to securely delete digital data are explored, different adversaries' capabilities are described, and how secure deletion approaches can be integrated into systems at different interface levels to protect against specific adversaries are shown.
Disposal of Disk and Tape Data by Secure Sanitization
TLDR
Recent disk drives with internal full disk encryption now implement an enhanced secure-erase command that takes only milliseconds to complete, according to federal guideline NIST 800-88.
Eraser: Your Data Won't Be Back
TLDR
This work presents a technique to provide secure deletion guarantees at file granularity, independent of the characteristics of the underlying storage medium, and describes an implementation of this scheme as a fileaware stackable block device deployed as a standalone Linux kernel module that does not require modifications to the operating system.
Data Deletion with Provable Security
TLDR
This paper presents a new approach to data storage for which a provably secure data deletion seems to be possible and provides rigid mathematical analysis of security of the proposed scheme for some scenarios even in the presence of an extremely powerful adversary.
The Packet Vault: Secure Storage of Network Data
TLDR
The packet vault is described, a cryptographically secured archiver of network packet data that captures network packets, encrypts them, and writes them to long-term CD-ROM storage for later analysis and for evidentiary purposes.

TLDR
This paper surveys the state-of-the-art secure deletion techniques that have been designed to pursue higher efficiency, verifiability, and portability for emerging types of hard disk drives and flash-based solid-state drives.
A framework for password harvesting from volatile memory
TLDR
The presence of confidential data in RAM such as user passwords is investigated and it is shown that even if the computer is switched off but not removed from the mains, the data are preserved.
