Single-level integrity and confidentiality protection for distributed shared memory multiprocessors

Brian Rogers, Chenyu Yan, Siddhartha Chhabra, Milos Prvulovic, Yan Solihin
2008 High-Performance Computer Architecture  
In this work we propose a new and efficient memory encryption and authentication solution for protecting the confidentiality and integrity of data in a DSM system.  ...  Then this processor will encrypt, sign, and communicate the data to the requesting processor which will decrypt and authenticate the data again, all using processor-to-processor protection mechanisms.  ...  Introduction Computer users are becoming increasingly aware of and concerned for the security of their computer systems.  ...

Transport layer security: how much does it really cost?

G. Apostolopoulos, V. Peris, D. Saha
1999 IEEE INFOCOM '99. Conference on Computer Communications. Proceedings. Eighteenth Annual Joint Conference of the IEEE Computer and Communications Societies. The Future is Now (Cat. No.99CH36320)  
The Secure Sockets Layer (SSL) protocol provides this capability and it is the most widely used transport layer security protocol.  ...  Since SSL is primarily used to secure web transactions, we use the SPECWeb96 benchmark suitably modified for use with the SSL protocol.  ...  This can take quite a while and so, for light loads, there is hardly any apparent reduction in latency even when there is session reuse.  ...

On Encrypting and Signing Binary XML Messages in the Wireless Environment

Jaakko Kangasharju, Tancred Lindholm, Sasu Tarkoma
2006 2006 IEEE International Conference on Web Services (ICWS'06)  
However, an alternate serialization format is not easily made compatible with XML security features such as encryption and signing.  ...  In the wireless world there has recently been much interest in alternate serialization formats for XML data, mostly driven by the weak capabilities of both devices and networks.  ...  XML Encryption also permits transformations to be applied, but these are performed only on referenced URIs to produce the actual encrypted bytes for the decrypter, and not on decrypted data.  ...

MACsec Layer 2 Security in HSR Rings in Substation Automation Systems

Jesús Lázaro, Armando Astarloa, José Araujo, Naiara Moreira, Unai Bidarte
2017 Energies  
At the lower level, added security must not interfere with the redundancy and the latency required for the real-time substation automation communications.  ...  This point-to-point securization happens at level 2, and this means that higher level protocols or applications are completely unaffected by the security protocol.  ...  As in the previous case, this means that non security aware equipment may be used and that the standard HSR latency is applied. At the same time, all communication can be secured if desired.  ...

Improving Memory Encryption Performance in Secure Processors

Jun Yang, Lan Gao, Youtao Zhang
2005 IEEE transactions on computers  
Due to the widespread software piracy and virus attacks, significant efforts have been made to improve security for computer systems.  ...  In this design, the program and data are stored in an encrypted format outside the CPU boundary. The decryption is carried out after they are fetched from memory and before they are used by the CPU.  ...  Other Security and Implementation Issues Context switching. One of the difficulties we realized is to handle a situation in context switching.  ...
