Background/Objectives: Security features are an essential part of recent smart metering systems. Smart meters are considered an important facility that must be protected by applying the latest security technologies.Methods/Statistical analysis: Security context determines the rules for applying/verifying security. DLMS/COSEM have Security suite to set of cryptographic algorithms. This is based on symmetric key based cryptographic communication. The high level security requires public key based cryptographic communication and digital signature.The security specification references the key scheme of DLMS-COSEM, which is based on a single set of unique symmetric keys per meter.Findings: we have studied a sequence for distributing security keys required by DLMS / COSEM.Our smart metering key distribution system can provide a security key management system such as key generation / distribution between AMI components. This is a PKI-based authentication using public key method (ECC), and a DLMS standard key distribution method after generating a session key using a public key. This system can also provide a key management scheme between DLMS clients not defined in the DLMS standard.Improvements/Applications: we analyze security requirements of DLMS/COSEM for secure smart metering and design key distribution/management method.

Current research in secure messaging for Vehicular Ad hoc Networks (VANETs) focuses on employing a digital certificate-based Public Key Cryptosystem (PKC) to support security. However, the security overhead of such a scheme creates a transmission delay and introduces a time-consuming verification process to VANET communications. This paper proposes a non-certificate-based public key management for VANETs. A comprehensive evaluation of performance and scalability of the proposed public key management regime is presented, which is compared with a certificate-based PKC by employing a number of quantified analyses and simulations. In this paper, the authors demonstrate that the proposal can maintain security and assert that it can improve overall performance and scalability at a lower cost, compared with certificate-based PKC. The proposed scheme adds a new dimension to key management and verification services for VANETs.

Most HEIs have piecemeal partially linked QMS (Quality Management System) or mechanisms to manage the data, statistics and documents heavy quality management of its academic aspirations disjointed from the planning dimension. The integrated eIQA structured in 9 e-modules are aimed at integrating the quality-information-planning trilogy into a paperless online real-time era of quality-information-planning management working in full tandem in conjunctions with each other holistically to support the key management and institution performance management and informed decision making. The linkages are establlished via the key reports, statistics, documents and action plans and projects required of quality management and accreditation across the QMS-PMS (Planning Management System) duo, as supported by a data warehouse and its applications data marts that interlinks the 9 e-modules in in eIQA.
