Flaws in a Verifiably Multiplicative Secret Sharing Scheme from ICITS 2017
secret sharing multiplicative verifiability
2018/1/27
In this paper, we point out flaws in an existing verifiably multiplicative secret sharing (VMSS) scheme. Namely, we show that a scheme proposed by Yoshida and Obana presented at ICITS 2017 is insecure...

England’s Reserve Markets Eliminating
2015/9/18
New England’s wholesale electricity market has been in operation, since May 1, 1999. When the
market began it was understood that the rules were not perfect (Cramton and Wilson 1998). However, it

Non-destructive Evaluation Method for Far-side Corrosion Type Flaws in Oil Storage Tank Bottom Floors Using the Magnetic Flux Leakage Technique
Non-destructive testing Magnetic leakage field Oil storage tank
2009/7/24
A quantitative procedure based on the magnetic flux leakage technique was proposed to evaluate the size of metal-loss type flaws such as corrosion pits in oil storage tank bottom floors. The approach...
Flaws in Some Self-Healing Key Distribution Schemes with Revocation
self-healing key distribution lower bounds polynomial interpolation
2009/6/5
Dutta and Mukhopadhyay have recently proposed some very efficient self-
healing key distribution schemes with revocation. The parameters of these
schemes contradict some results (lower bounds) prese...
Security Flaws in Several Group Signatures Proposed by Popescu
group signature digital signature information security
2009/4/10
In resent years, Popescu proposed several group signature
schemes based on the Okamoto-Shiraishi assumption in [8{11], and claimed
his schemes are secure. However, this paper demonstrates that these...

Security Flaws Pairing-based Group Signature Scheme
2009/4/1
Deng and Zhao recently proposed a group signature scheme in [1].We find that the scheme cannot satisfy all of the requirements of a secure group signature.Keywords group signature scheme, bilinear pai...
Cryptanalytic Flaws in Oh et al.’s ID-Based Authenticated Key Agreement Protocol
Cryptanalytic Flaws ID-Based Authenticated Key Protocol
2008/5/23
A key agreement protocol is designed for two or more
entities to agree upon a shared secret key, which is used
to preserve confidentiality and data integrity over an open
network. In 2007, Oh et al...
