Abstract—Resource and cost constraints remain a challenge for wireless sensor network security. In this paper, we propose a new approach to protect confidentiality against a parasitic adversary, which seeks to exploit sensor networks by obtaining measureme ...
Confidential communication aided by a relay without security clearance is studied. General strategies and outer bounds are derived for the problem of secret communication and secret key generation when correlated observations at all terminals are available ...

Stream ciphers are fast cryptographic primitives to provide confidentiality of electronically transmitted data. They can be very suitable in environments with restricted resources, such as mobile devices or embedded systems. Practical examples are cell pho ...
Trusted Execution Environments (TEEs), such as Intel SGX enclaves, use hardware to ensure the confidentiality and integrity of operations on sensitive data. While the technology is available on many processors, the complexity of its programming model and i ...
Wireless sensor networks are already deployed in numerous occasions. As this technology matures towards wider adoption, security will become an increasingly important requirement. However, resource and cost constraints for the low-complexity sensor nodes r ...
In the three-screen installation "CONFIDENTIAL" (2018) Bertschi traces the spirit of six buildings in Johannesburg’s Central Business District and Pretoria. In South Africa's National Archives, she discovered correspondence documenting the extensive purcha ...
The progress in the diffusion of solid oxide fuel cell (SOFC) as commercial devices is not paired by literature production. Articles describing the behaviour of SOFC stacks are rare because of confidentiality reasons for commercial suppliers while research ...
