No peeking: privacy-preserving demand response system in smart grids

Depeng Li, Zeyar Aung, John R. Williams, Abel Sanchez
2013 International Journal of Parallel, Emergent and Distributed Systems  
Without a well-designed privacy preservation mechanism, adversaries can capture, model and divulge customers' behaviour and activities.  ...  Unfortunately, privacy violation becomes a pressing challenge that drastically affects the DR programs. Power usage and operational data can be abused to infer personal information of customers.  ...  From an adversary's perspective, we practically illustrate privacy threats with the aid of corresponding examples.  ...

eSKAMI: Efficient and Scalable Multi-group Key Management for Advanced Metering Infrastructure in Smart Grid

Mourad Benmalek, Yacine Challal
2015 2015 IEEE Trustcom/BigDataSE/ISPA  
It is a key management scheme that can support unicast, multicast and broadcast communications based on an efficient Multi-group Key graph technique.  ...  AMI is an enabling technology for Smart Grid (SG) and hence represents a privileged target for security attacks with potentially great damage against infrastructures and privacy.  ...  An automatic verification of security with an automated validation tool like AVISPA is also in our perspectives.  ...

Predistribution and local collaboration-based group rekeying for wireless sensor networks

Wensheng Zhang, Sencun Zhu, Guohong Cao
2009 Ad hoc networks  
To address this problem, we propose a family of predistribution and local collaboration-based group rekeying (PCGR) schemes, which update the compromised group keys to prevent the compromised nodes from  ...  To the best of our knowledge, our schemes are the first set of distributed group rekeying schemes for sensor networks without involving online key servers.  ...  We also compare the performance of the proposed schemes with several existing group rekeying schemes.  ...

Impacts of S1 and X2 Interfaces on eMBMS Handover Failure: Solution and Performance Analysis

Yi Ren, Jyh-Cheng Chen, Jui-Chih Chin
2018 IEEE Transactions on Vehicular Technology  
In this paper, we point out a new handover failure problem in eMBMS due to the miss of rekeying information. We first take a close look at the new handover scenarios.  ...  Moreover, we propose a solution to combat against the handover failure.  ...  When a member joins/leaves the group, a group key needs to be updated to add/revoke the member. The process is referred to as rekeying.  ...

On replacing cryptographic keys in hierarchical key management systems

Anne V.D.M. Kayem, Selim G. Akl, Patrick Martin
2008 Journal of Computer Security  
Each group is assigned a single cryptographic key that is used for encryption/decryption.  ...  Data re-encryption is time-consuming, so, rekeying creates delays that impede performance.  ...  Results for each case are obtained from averages of over 10 runs, with random numbers of rekey requests expressed as proportions of a user group with a maximum of 100 members and files (versions of the  ...

In other words, unlike in our setting, HUTN provides a fixed concrete syntax with fixed scoping rules. TMDIFF allows languages to have custom syntax, and custom binding semantics.  ...  First the machine is extended with a locked state in Doors 2 (Fig. 4a ). Second, Doors 3 (Fig. 4b ), shows a grouping feature of the language: the locked state is part of the locking group.  ...

A Formal Analysis of IEEE 802.11's WPA2: Countering the Kracks Caused by Cracking the Counters

Cas Cremers, Benjamin Kiesl, Niklas Medinger
2020 USENIX Security Symposium  
In particular, it involves various mechanisms that interact with each other in subtle ways, which offers little hope for modular reasoning.  ...  Our model is the first that is detailed enough to detect the KRACK attacks; it includes mechanisms such as the four-way handshake, the group-key handshake, WNM sleep mode, the dataconfidentiality protocol  ...  A rekey of the group temporal key can involve a new iteration of the four-way handshake with one supplicant (the one who initiated the rekey) and socalled group-key handshakes with the other supplicants  ...

Key Management Systems for Smart Grid Advanced Metering Infrastructure: A Survey [article]

Amrita Ghosal, Mauro Conti
2018 arXiv   pre-print
We also provide a classification of the existing works in literature that deal with secure key management system in AMI. Finally, we identify possible future research directions of KMS in AMI.  ...  Thus, AMI plays a significant role in the smooth functioning of smart grids. AMI is a privileged target for security attacks as it is made up of systems that are highly vulnerable to such attacks.  ...  The scheme is based on a multi-group key graph structure that supports the management of multiple demand response projects concurrently for every customer.  ...
