Genome‐Wide CRISPR Screen Identifies a microRNA Orchestrating Pleiotropic Resistance to Targeted Therapy and T Cell Immunity in Melanoma

Advanced Science, EarlyView.
A genome‐wide microRNA CRISPR screen identifies miR‐18a as a master regulator of cross‐resistance in melanoma. Loss of miR‐18a activates the AJUBA–YAP/Hippo axis to confer BRAFi resistance and enhances THBS1–CD47 interaction to impair CD8+ T cell immunity. hnRNP A1 is identified as an upstream regulator of miR‐18a processing.

Functional Analysis of Ligand‐Gated Chloride Channels in a Cnidarian Sheds Light on the Evolution of Inhibitory Signaling

Advanced Science, EarlyView.
We uncover a large variety of putative inhibitory ligand‐gated ion channels (LGICs) in the phylum Cnidaria, the sister group to all bilaterian animals. Phylogenetic analysis suggests a complex evolutionary history of inhibitory LGICs with diverse neurotransmitter ligands.

Mechanostimulatory Cues Determine Intestinal Fibroblast Fate and Profibrotic Remodeling in a Physiodynamic Human Gut‐on‐a‐Chip

Advanced Science, EarlyView.
A healthy gut barrier shields underlying fibroblasts from luminal shear forces, illustrating that “good fences make good neighbors.” Barrier damage exposes fibroblasts to shear stress, inducing cell death and the emergence of stress‐adapted, profibrotic fibroblasts. Sustained shear exposure promotes the formation of stiff aggregates of mechanoadapative

On quantum authentication protocols

GLOBECOM '05. IEEE Global Telecommunications Conference, 2005., 2005
When it became known that quantum computers could break the RSA (named for its creators - Rivest, Shamir, and Adleman) encryption algorithm within a polynomial-time, quantum cryptography began to be actively studied. Other classical cryptographic algorithms are only secure when malicious users do not have computational power enough to break security ...

Robust and Simple Authentication Protocol

The Computer Journal, 2003
Summary: Password-based authentication protocols are currently the conventional authentication protocols in many distributed systems. However, the security of these protocols is falling behind the times because more and more attacks can now break them.

A new family of authentication protocols

ACM SIGOPS Operating Systems Review, 1998
We present a related family of authentication and digital signature protocols based on symmetric cryptographic primitives which perform substantially better than previous constructions. Previously, one-time digital signatures based on hash functions involved hundreds of hash function computations for each signature; we show that given online access to ...

Designing an Authentication Protocol via Authentication Test

2007 IEEE Symposium on Computers and Communications, 2007
The proving process of protocol with authentication test suggests a design process of a proper authentication protocol. This paper inherits the idea of designing protocols via authentication test, and then describes the thought and procedure of designing protocols in terms of authentication test from protocol analyzing standpoint.

Authentication Primitives for Protocol Specifications

2003
We advocate here the use of two authentication primitives we recently propose in a calculus for distributed systems, as a further instrument for programmers interested in authentication. These primitives offer a way of abstracting from various specifications of authentication and obtaining idealized protocols “secure by construction”.

A Mutual Authentication Protocol for RFID

IT Professional, 2011
Designing a security protocol for RFID systems is difficult because RFID tags have limited power-consumption and memory capabilities. A mutual authentication protocol based on a hash function helps prevent attacks against RFID systems.

Authenticity by typing for security protocols

Proceedings. 14th IEEE Computer Security Foundations Workshop, 2001., 2005
Abstract: We propose a new method to check authenticity properties of cryptographic protocols. First, code up the protocol in the spi-calculus of Abadi and Gordon. Second, specify authenticity properties by annotating the code with correspondence assertions in the style of Woo and Lam.
