KP+ : Fixing Availability Issues on KP Ownership Transfer Protocols
RFID cryptanalysis privacy
2016/12/8
Ownership Transfer Protocols for RFID allow transferring the rights over a tag from a current owner to a new owner in a secure and private way. Recently, Kapoor and Piramuthu have proposed two schemes...
Cryptographic Solutions for Credibility and Liability Issues of Genomic Data
homomorphic signatures aggregate signatures genomic privacy
2016/5/20
In this work, we consider a scenario that includes an individual sharing his genomic data (or results obtained from his genomic data) with a service provider. In this scenario, (i) the service provide...
Another Look at Tightness II: Practical Issues in Cryptography
tightness complexity leveraging HMAC
2016/4/12
How to deal with large tightness gaps in security proofs is a vexing issue in
cryptography. Even when analyzing protocols that are of practical importance, leading
researchers often fail to treat th...
The most widely used secure Internet communication standard TLS (Transport Layer Security) has an optional client certificate authentication feature that in theory has significant security advantages ...
A Study of Goldbach's conjecture and Polignac's conjecture equivalence issues
Goldbach's conjecture Polignac's conjecture Equivalent
2013/12/19
The famous Goldbach's conjecture and Polignac's conjecture are two of all unsolved problems in the field of number theory today. As well known, the Goldbach's conjecture and the Polignac's conjecture ...
Definitional Issues in Functional Encryption
Definitional Issues Functional Encryption security notions
2010/11/1
We formalize the emergent notion of ``functional encryption,'' as well as introduce various security notions for it, and study relations among the latter. In particular, we show that indistinguishabil...
The paper briefly examines some issues arising with respect to the economic sanctions imposed on Iraq, particularly their objectives, targets, and effects. It suggests that the sanctions are failing, ...
Within the next year, travelers from dozens of nations
may be carrying a new form of passport in response to a
mandate by the United States government. The e-passport,
as it is sometimes called, re...
