Tight Time-Memory Trade-Offs for Symmetric Encryption [PDF]

, 2019
Concrete security proofs give upper bounds on the attacker’s advantage as a function of its time/query complexity. Cryptanalysis suggests however that other resource limitations – most notably, the attacker’s memory – could make the achievable advantage smaller, and thus these proven bounds too pessimistic.

Transparent memory encryption and authentication

2017 27th International Conference on Field Programmable Logic and Applications (FPL), 2017
Security features of modern (SoC) FPGAs permit to protect the confidentiality of hard- and software IP when the devices are powered off as well as to validate the authenticity of IP when being loaded at startup. However, these approaches are insufficient since attackers with physical access can also perform attacks during runtime, demanding for ...

Minimizing performance overhead in memory encryption

Journal of Cryptographic Engineering, 2013
Modern communications devices process, distribute and store massive amounts of data compared to only a few years ago. These devices can contain very sensitive information. In addition, they are used in uncontrolled, open environments where they can be lost or compromised.

Crash-Consistency-Aware Encryption for Non-Volatile Memories

50th International Conference on Parallel Processing, 2021
Data security is a very important issue in non-volatile memory (NVM) systems. Due to high security and low decryption latency, counter mode encryption (CME) is often used, which unfortunately suffers from extra efforts to guarantee the crash consistency of counters.

Memory protection challenges: Attacks on memory encryption

Cyber Security: A Peer-Reviewed Journal, 2017
This paper explains some of the challenges involved in protecting the system memory of a computing platform against adversaries who can read and modify its contents. To clarify the limitations and effectiveness of different defence mechanisms, we lay out a threat model, coupled with a set of assumptions on the adversarial capabilities, for a variety of

Improving Memory Encryption Performance in Secure Processors

IEEE Transactions on Computers, 2005
Due to the widespread software piracy and virus attacks, significant efforts have been made to improve security for computer systems. For stand-alone computers, a key observation is that, other than the processor, any component is vulnerable to security attacks. Recently, an execution only memory (XOM) architecture has been proposed to support copy and

In-memory encryption using the advanced encryption standard

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences
Encryption and decryption of data with very low latency and high energy efficiency is desirable in almost every application that deals with sensitive data. The advanced encryption standard (AES) is a widely adopted algorithm in symmetric key cryptography with numerous efficient implementations.

Attacks on Encrypted Memory and Constructions for Memory Protection

2016 Workshop on Fault Diagnosis and Tolerance in Cryptography (FDTC), 2016
The first part of the talk discusses some potential implications of attacks on the system memory of a computing platform. We show that encryption to protect privacy is not necessarily sufficient to protect against active attacks. In the second part of the talk, we explore the Memory Encryption Engine, which is part of Intel's Software Guard Extensions (

Memory leakage-resilient searchable symmetric encryption

Future Generation Computer Systems, 2016
Along with the popularization and rapid development of cloud-computing, more and more individuals and enterprises choose to store their data in cloud servers. However, in order to protect data privacy and deter illegal accesses, the data owner has to encrypt his data before outsourcing it to the cloud server.
