A Constructive Perspective on Key Encapsulation [chapter]

Sandro Coretti, Ueli Maurer, Björn Tackmann
2013 Lecture Notes in Computer Science  
A key-encapsulation mechanism (KEM) is a cryptographic primitive that allows anyone in possession of some party's public key to securely transmit a key to that party.  ...  The goal of a KEM is to construct a resource that models a shared key available to the honest parties.  ...  Key-Encapsulation Mechanisms A key-encapsulation mechanism (KEM) with key space K is a triple of algorithms Π = (K, E, D).  ...

Efficient Certificateless Signcryption Tag-KEMs for Resource-constrained Devices [article]

Wenhao Liu, Maurizio Adriano Strangio, Shengbao Wang
2015 arXiv   pre-print
Efficient certificateless one-pass session key establishment protocols can be constructed from key encapsulation mechanisms (KEMs) by making use of tags and signcryption schemes.  ...  ., the second, named DKTUTS-CLSC-TKEM, is based on the direct key transport using a timestamp (DKTUTS) protocol first described by Zheng.  ...  In the CLC setting user private keys are constructed from two partial secrets: one generated by the KGC computed from the user's identity and a secret master key and a secret value chosen by the user itself  ...

Explication of object-oriented databases

Adair Dingle, David Umphress, Russ Moul
1998 Proceedings of the twenty-ninth SIGCSE technical symposium on Computer science education - SIGCSE '98  
. , Ambler defines three normal forms [l-3] . 1 ONE and 20NF promote the desired construction of objects in that they guarantee the encapsulation of attributes with related finctionality. 30NF restricts  ...  There, is no notion of uniqueness; nor is there any construct corresponding to the primary key.  ...  However, by looking at both types of databases from a software engineering perspective, the parallels quickly come to light.  ...

Jean-Frederic Levesque, Kim Sutherland
2020 BMC Health Services Research  
They reflect four performance perspectives (patient, population, delivery organisation and system).  ...  Internationally, healthcare systems and researchers have used a variety of terms to categorise indicators of healthcare performance, however few frameworks are based on a theoretically-based conceptual  ...  A previous iteration of the framework was published in BHI reports, when the authors were employed by that organisation.  ...

Building Better Signcryption Schemes with Tag-KEMs [chapter]

Tor E. Bjørstad, Alexander W. Dent
2006 Lecture Notes in Computer Science  
To prove the effectiveness of this construction, we will provide several examples of secure signcryption tag-KEMs, including a brand new construction based on the Chevallier-Mames signature scheme [8]  ...  Signcryption schemes aim to provide all of the advantages of simultaneously signing and encrypting a message.  ...  The usual construction paradigm, known as the KEM-DEM construction, consists of two parts: a key encapsulation mechanism (KEM) and a data encapsulation mechanism (DEM).  ...

Recent developments in multifunctional hybrid nanoparticles: opportunities and challenges in cancer therapy

Carolina, Salvador Morales
2012 Frontiers in Bioscience (Elite Edition)  
The result is quantum-dots encapsulated in a lipid envelope. A modification of this procedure can be implemented to encapsulate more than one imaging agent in a single construct.  ...  Quantum dot-lipid hybrid nanoparticles is another construct in which imaging agents are encapsulated inside a lipid.  ...

Construction and Exploration of Corporate Virtual Private Networks

Kai Peng
2012 Advanced Engineering Forum  
One solution is to use virtual private network when constructing enterprise information environment.  ...  From perspective of engineering, comparison between the construction of corporate VPN and tunneling protocol that realizes VPN is made.  ...  VPN based on IP simulates a private WAN to use IP mechanism, and is a technology that simulates a point-to-point line on the public data network through private tunnel technology.  ...

Verifiable Random Functions from Identity-Based Key Encapsulation [chapter]

Michel Abdalla, Dario Catalano, Dario Fiore
2009 Lecture Notes in Computer Science  
We propose a methodology to construct verifiable random functions from a class of identity based key encapsulation mechanisms (IB-KEM) that we call VRF suitable.  ...  Our construction is of interest both from a theoretical and a practical perspective.  ...  Our VRF construction relies on a special class of identity based key encapsulation mechanisms that we call VRF suitable.  ...

Externalisation and Internalization: A New Perspective on Agent Modularisation in Multi-Agent System Programming [chapter]

Alessandro Ricci, Michele Piunti, Mirko Viroli
2010 Lecture Notes in Computer Science  
Existing solutions typically propose some kinds of constructs -such as capabilities -to group and encapsulate in well-defined modules inside the agent different kinds of agent features, that depend on  ...  In this paper we introduce a further perspective, which can be considered complimentary to existing approaches, which accounts for externalizing some of such functionalities into the computational environment  ...  The artifact abstraction is a key concept on which is the contribution of this paper is based.  ...
