Cloud computing is a rapidly growing internet based computing that endeavors to be dynamic, reliable and available with guaranteed quality of service. This has become a sophisticated computing platform or technology for customers as well as organizations for its availability of resources such as software, storage and network with minimum cost. Using the business model like Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a service (IaaS) this environment have increased distribute computing capacity. Preserving confidentiality, integrity and availability are the vexing issues in cloud computing environment. This paper highlights cloud computing threats and proposes a distributed and efficient encryption algorithm to enhance the data security in cloud.

“…The schemes are usually based on bilinear pairing, which can be applied efficiently because of the property of linearity in both components. The ideas of the multi‐proxy signature schemes in were to let proxy signers have the right to sign a message with a warrant from the original signer so that such authentication can be performed even when the original signer is not available. However, this foundation does not apply to the signature in the AMI downlink transmission because the authenticate server (AS) is always available.…”

HIBaSS: hierarchical identity‐based signature scheme for AMI downlink transmission

The advanced metering infrastructure (AMI) is the key to demand‐side management system in smart grid. The communication over AMI consists of plenty important data, which have different security requirements. In this paper, we propose a hierarchical identity‐based signature scheme (HIBaSS) to enhance the sender authentication for downlink transmission of AMI. The downlink in AMI mainly distributes control messages such as price and tariff information to the smart meters. Unlike the metering data in the uplink transmission that requires confidentiality, most of the control messages in downlink only require data integrity and sender authentication. Moreover, since most of the control messages are valid for a relatively long time period (e.g., an hour), more complicated but stronger cryptographic schemes can be applied in downlink AMI. In our proposed HIBaSS, each smart meter does not trust a signature from a single data aggregate point (DAP) although it includes the original signature from the authentication server (AS), because a smart meter has no way to verify a message or a DAP directly with the AS. Instead, a smart meter receives a group signature created by all the DAPs with certificates from the AS that prevents the messages from forgery, manipulation and repudiation. The performance evaluation also shows that HIBaSS is efficient enough to be applied in the AMI downlink transmission. Copyright © 2015 John Wiley & Sons, Ltd.

Abstract. The notion of identity-based proxy signature with message recovery feature has been proposed to shorten identity-based proxy signatures and improve their communication overhead since signed messages are not transmitted with these kinds of signatures. There are a few schemes for this notion: Singh and Verma's scheme and Yoon et al.'s scheme. Unfortunately, Tian et al. by presenting two forgery attacks show that Singh and Verma's scheme is not secure, and also Yoon et al.'s scheme does not support provable security. The contributions of this paper are twofold. First, we review Yoon et al.'s scheme and discuss why it does not have message recovery property, and consequently it is not short. Second, we propose a short identity-based proxy signature scheme with the help of message recovery property, and show that it is secure under CDH assumption in the random oracle model. Furthermore, our scheme is more efficient than (as efficient as) previous identity-based proxy signatures.Keywords: identity-based signature, identity-based signature with message recovery, identity-based proxy signature, CDH assumption, random oracle model.
