Intercept Probability Analysis of Cooperative Wireless Networks with Best Relay Selection in the Presence of Eavesdropping Attack

, 2013
Due to the broadcast nature of wireless medium, wireless communication is extremely vulnerable to eavesdropping attack. Physical-layer security is emerging as a new paradigm to prevent the eavesdropper from interception by exploiting the physical ...

Two‐Dimensional Reconfigurable Photodiode for In‐Sensor Color Filtering and Spectral Logic

Advanced Materials, EarlyView.
By harnessing the photodoping of different aggregates, the device exhibits wavelength‐dependent volatile‐to‐nonvolatile photoresponses that can be reconfigured via bias modulation. This enables in‐sensor color filtering and spectral‐encrypted information processing, eliminating reliance on external optical filters or post‐processing algorithms ...

Forward Secure Non-Interactive Key Exchange [PDF]

, 2014
Exposure of secret keys is a major concern when cryptographic protocols are implemented on weakly secure devices. Forward security is thus a way to mitigate damages when such an event occurs. In a forward-secure scheme, the public key is indeed fixed while the secret key is updated with a one-way process at regular time periods so that security of the ...

BLOC: Buildable and Linkable Organ on a Chip

Advanced Materials Technologies, EarlyView.
We developed a “Buildable and Linkable Organ on a Chip” (BLOC) that can construct diverse microphysiological systems (MPSs). The BLOC is standardized to the same size and has one of the functions of “Culture,” “Control,” or “Analysis.” Users can freely configure various MPSs, including developing perfusion, cytotoxicity analysis, and biochemical ...

Forward and Backward Private Searchable Encryption for Cloud-Assisted Industrial IoT

Sensors
In the cloud-assisted industrial Internet of Things (IIoT), since the cloud server is not always trusted, the leakage of data privacy becomes a critical problem. Dynamic symmetric searchable encryption (DSSE) allows for the secure retrieval of outsourced

Cryptanalysis of AES-PRF and Its Dual

IACR Transactions on Symmetric Cryptology, 2018
A dedicated pseudorandom function (PRF) called AES-PRF was proposed by Mennink and Neves at FSE 2018 (ToSC 2017, Issue 3). AES-PRF is obtained from AES by using the output of the 5-th round as the feed-forward to the output state.
