Advanced metering infrastructure (AMI) is a key part of the smart grid; thus, one of the most important concerns is to offer a secure mutual authentication.  This study focuses on communication between a smart meter and a server on the utility side. Hence, a mutual authentication mechanism in AMI is presented based on the elliptic curve cryptography (ECC) and one time signature (OTS) consists o...

identification, authentication and quality control are essential to ensure safety, therapeutic potency, efficacy and reproducible quality of herbal medicines. The aim of this study is to use taxonomic method for authentication of traditional herbal drugs which are commonly sold in herbal shops in Iran. In this regard, twenty-seven cases of herbal drugs suspected to be adulterated were investiga...

The purpose of this paper is to present the design for providing security and higher authentication scheme for executing secure data transaction in an Organization field over Internet. There has been incessant change in technology day by day, so security mechanisms like authentication schemes are also required to be updated. Authentication schemes that involve more than single level for authent...

This exposition paper suggests a new low-bandwidth publickey encryption paradigm. The construction turns a weak form of key privacy into message privacy as follows: let E be a public-key encryption algorithm. We observe that if the distributions E(pk0, •) and E(pk1, •) are indistinguishable for two public keys pk0, pk1, then a message bit b ∈ {0, 1} can be embedded in the choice of pkb. As the ...

Current secure multiparty protocols have the following deficiency. The public transcript of the communication can be used as an involuntary commitment of the parties to their inputs and outputs. Thus parties can be later coerced by some authority to reveal their private data. Previous work that has pointed this interesting problem out contained only partial treatment. In this work we present th...
