AD‐ASGKA – authenticated dynamic protocols for asymmetric group key agreement

Security and Communication Networks, 2016
AbstractAsymmetric group key agreement is a cryptographic primitive allowing a group of users to negotiate a common public encryption key while each of them holds a different secret private decryption key. Anyone (including outsiders) with the public encryption key can send encrypted messages to the group members, and then the group members can decrypt

Blockchain-Based Asymmetric Group Key Agreement Protocol for Mobile Ad Hoc Network

International Symposium on Security and Privacy in Social Networks and Big Data, 2019
Group key agreement is one of the key technologies for ensuring information exchange security among group members. It is widely used in secure multiparty computation, resource security sharing, and distributed collaborative computing et al. The current group key agreement requires personal privacy protection, lightweight computing and more efficient ...

Integrate the hierarchical cluster elliptic curve key agreement with multiple secure data transfer modes into wireless sensor networks

Connection Science, 2022
Since sensor nodes in wireless sensor networks or Internet of things have limited resources, achieving secure data transmissions among nodes is a challenge. Hence, efficient key management schemes with lightweight ciphers are essential.

Novel 5G Authentication Protocol to Improve the Resistance Against Active Attacks and Malicious Serving Networks

IEEE Access, 2019
The security of mobile communication largely depends on the strength of the authentication key exchange protocol. The 3rd Generation Partnership Project (3GPP) Group has standardized the 5G AKA (Authentication and Key Agreement) protocol for the next ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
