A resilient key predistribution scheme for multiphase wireless sensor networks [PDF]
, 2009 In wireless sensor networks, sensor nodes eventually die due to battery depletion. Wireless sensor networks (WSNs) in which new nodes are periodically redeployed with certain intervals, called generations, to replace the dead nodes are called multi-phase

A Blockchain-Based Authentication and Dynamic Group Key Agreement Protocol
Sensors, 2020 With the rapid development of mobile networks, there are more and more application scenarios that require group communication. For example, in mobile edge computing, group communication can be used to transmit messages to all group members with minimal ...

Using Backward Induction Techniques in (Timed) Security Protocols Verification [PDF]
, 2013 This paper shows a new way of automatic verification of properties of untimed and timed security protocols. To do this we use a modified version of previously introduced formal model based on a network of synchronized (timed) automata that expreses behaviour and distributed knowledge of users during protocol executions.

Uneven key pre-distribution scheme for multi-phase wireless sensor networks [PDF]
, 2013 In multi-phase Wireless Sensor Networks (WSNs), sensor nodes are redeployed periodically to replace nodes whose batteries are depleted. In order to keep the network resilient against node capture attacks across different deployment epochs, called ...

Bell's Theorem Versus Local Realism in a Quaternionic Model of Physical Space [PDF]
, 2019 In the context of EPR-Bohm type experiments and spin detections confined to spacelike hypersurfaces, a local, deterministic and realistic model within a Friedmann-Robertson-Walker spacetime with a constant spatial curvature (S^3 ) is presented that ...

Sensors, 2022 Because the majority of information in the industrial Internet of things (IIoT) is transmitted over an open and insecure channel, it is indispensable to design practical and secure authentication and key agreement protocols.

XDRBG: A Proposed Deterministic Random Bit Generator Based on Any XOF
IACR Transactions on Symmetric CryptologyA deterministic random bit generator (DRBG) generates pseudorandom bits from an unpredictable seed, i.e., a seed drawn from any random source with sufficient entropy.

DSTC: DNS-based Strict TLS Configurations
, 2018 Most TLS clients such as modern web browsers enforce coarse-grained TLS security configurations. They support legacy versions of the protocol that have known design weaknesses, and weak ciphersuites that provide fewer security guarantees (e.g.

A highly resilient and zone-based key predistribution protocol for multiphase wireless sensor networks [PDF]
, 2009 Pairwise key distribution among the sensor nodes is an essential problem for providing security in Wireless Sensor Networks (WSNs). The common approach for this problem is random key predistribution, which suffers from resiliency issues in case of node ...

Attribute-based revocable collaborative access control scheme
Tongxin xuebao, 2021 To solve the dynamic update of access rights in attribute-based collaborative access control, a novel scheme was proposed with the revocation of attribute, user and collaborative policy.A formal definition and a security model were presented, the group ...
