Rethinking Secure FPGAs: Towards a Cryptography-friendly Configurable Cell Architecture and its Automated Design Flow
eFPGA ASIC
2018/8/8
This work proposes the first fine-grained configurable cell array specifically tailored for cryptographic implementations. The proposed architecture can be added to future FPGAs as an application-spec...
In this position paper, we initiate a systematic treatment of reaching consensus in a permissionless network. We prove several simple but hopefully insightful lower bounds that demonstrate exactly why...
Rethinking Privacy for Extended Sanitizable Signatures and a Black-Box Construction of Strongly Private Schemes
sanitizable signatures privacy unlinkability
2015/12/23
Sanitizable signatures, introduced by Ateniese et al. at ESORICS’05,
allow to issue a signature on a message where certain predefined
message blocks may later be changed (sanitized) by some dedicate...
Rethinking Definitions of Security for Session Key Agreement
Key Exchange Definitions Public Key Infrastructure
2013/4/18
We consider session key agreement (SKA) protocols operating in a public key infrastructure, with pre-specified peers, that take no session ID as input, and output only a session key. Despite much work...
Rethinking the security of some authenticated group key agreement schemes
Rethinking authenticated group key agreement schemes
2009/4/3
In this paper we analyse three improved authenticated group key agreement
schemes, all of which are based on the conference key distribution systems
proposed by Burmester and Desmedt. We show that a...
