Improving Memory Encryption Performance in Secure Processors
IEEE Transactions on Computers, 2005Due 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

Memory leakage-resilient searchable symmetric encryption
Future Generation Computer Systems, 2016Along 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.

An Image Encryption System by Cellular Automata with Memory
2008 Third International Conference on Availability, Reliability and Security, 2008In this paper, an Image Encryption System by special kind of cellular automata (cellular automata with memory) and also an appropriate transition function for the cryptosystem have been proposed. Also a lossy idea is used to present a secure cryptosystem.

ACM SIGARCH Computer Architecture News, 2005
Memory encryption has become a common approach to providing a secure processing environment, but current schemes suffer from extra performance and storage overheads. This paper presents predecryption as a method of providing this security with less overhead by using well-known prefetching techniques to retrieve data from memory and perform decryption ...

Dynamic encryption key design and management for memory data encryption in embedded systems
2013 IEEE Computer Society Annual Symposium on VLSI (ISVLSI), 2013To effectively encrypt data memory contents of an embedded processor, multiple keys which are dynamically changed are necessary. However, the resources required to store and manage these keys on-chip (so that they are secure) can be extensive. This paper presents a design where each dynamic key is determined by a random number, a counter value, and a ...

Tight Time-Memory Trade-Offs for Symmetric Encryption
2019Concrete 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.

Object-oriented Unified Encrypted Memory Management for Heterogeneous Memory Architectures
Proceedings of the ACM on Management of DataIn contemporary database applications, the demand for memory resources is intensively high. To enhance adaptability to varying resource needs and improve cost efficiency, the integration of diverse storage technologies within heterogeneous memory architectures emerges as a promising solution. Despite the potential advantages, there exists a significant

In modern operating systems, cryptographic file systems can protect confidential data from unauthorized access. However, once an authorized process has accessed data from a cryptographic file system, the data can appear as plaintext in the unprotected virtual memory backing store, even after system shutdown.
