Trusted Certified Auditor Using Cryptography for Secure Data Outsourcing and Privacy Preservation in Fog-Enabled VANETs

With the recent technological developments,massive vehicular ad hoc networks(VANETs)have been established,enabling numerous vehicles and their respective Road Side Unit(RSU)components to communicate with oneanother.The best way to enhance traffic flow for vehicles and traffic management departments is to share thedata they receive.There needs to be more protection for the VANET systems.An effective and safe methodof outsourcing is suggested,which reduces computation costs by achieving data security using a homomorphicmapping based on the conjugate operation of matrices.This research proposes a VANET-based data outsourcingsystem to fix the issues.To keep data outsourcing secure,the suggested model takes cryptography models intoaccount.Fog will keep the generated keys for the purpose of vehicle authentication.For controlling and overseeingthe outsourced data while preserving privacy,the suggested approach considers the Trusted Certified Auditor(TCA).Using the secret key,TCA can identify the genuine identity of VANETs when harmful messages aredetected.The proposed model develops a TCA-based unique static vehicle labeling system using cryptography(TCA-USVLC)for secure data outsourcing and privacy preservation in VANETs.The proposed model calculatesthe trust of vehicles in 16 ms for an average of 180 vehicles and achieves 98.6%accuracy for data encryption toprovide security.The proposedmodel achieved 98.5%accuracy in data outsourcing and 98.6%accuracy in privacypreservation in fog-enabled VANETs.Elliptical curve cryptography models can be applied in the future for betterencryption and decryption rates with lightweight cryptography operations.

Certifying assembly programs with trails

In this paper, we introduce a new way of certifying assembly programs. Unlike previous program logics, we extract the control-flow information from the code and generate an intermediate trail between the specification and the real code. Trails are auxiliary specifications and treated as modules in the certification process. We define a simple modular program logic called trail-based certified assembly programming （TCAP） to certify and link different parts of a program using the corresponding trails. Because the control flow information in trails is explicit, the rules are easier to design. We show that our logic is powerful enough to prove partial correctness of assembly programs with features including stack-based abstractions and self-modifying code. We also provide a semantics for TCAP and prove that the logic is sound with respect to the semantics.

A New Proxy Signature Scheme with Message Recovery Using Self-Certified Public Key

A proxy signature scheme with message recovery using self-certified public key is proposed, which withstands public key substitution attacks, active attacks, and forgery attacks. The proposed scheme accomplishes the tasks of public key verification, proxy signature verification, and message recovery in a logically single step. In addition, the proposed scheme satisfies all properties of strong proxy signature and does not use secure channel in the communication between the original signer and the proxy signature signer.

Determination of Hf–Sr–Nd isotopic ratios by MC-ICP-MS using rapid acid digestion after flux-free fusion in geological materials

In this study, we established a rapid acid digestion for determining Hf-Sr-Nd isotopic ratios of geological samples by using MC-ICP-MS. Conditions of 1600 ℃ for 1 min and 1400 ℃ for 1 min were adopted for fusing intrusive rocks and extrusive rocks, respectively. The rapid acid digestion technique is superior in digestion time compared with high-pressure PTFE bomb method. The procedural blanks of the method were also lower than that flux fusion. Replicate analyses of international certified reference materials （CRMs） indicate that isotopic ratios of ^176Hf/^177Hf, ^87Sr/^86Sr and 143Nd/144Nd agree well with previously published data. The external reproducibility （2SD, n = 5） of ten CRMs are ±0.000030 for ^87Sr/^86Sr, ± 0.000030 for ^143Nd/^144Nd, and ±0.000018 for ^176Hf/^177Hf.

Voluntary emission reduction market in China: development, management status and future supply

The voluntary emission reduction (VER) trading mechanism has played an important role in China’s seven pilot carbon markets. From a comprehensive review of the VER trading and offsetting mechanisms since 2013, this study analyses the quality management of the Chinese Certified Emission Reduction (CCER) in the pilot carbon markets, conducts a comparative analysis of the geographical and field distributions of proposed and registered projects and emission reductions and provides the CCER supply outlook for 2020 in the aspects of on record, project registration, emission reduction registration and emission reduction issuance. Results show that the potential number of CCER projects by 2020 will be 2,864, 1,047, 818, and 286 with the corresponding emission reductions amounting to 493, 212, 133, and 49 million tCO2e, respectively. Although considerable progress has been made, China remains confronted with many challenges in developing the VER trading system. Accordingly, policy stability and continuity and guarding against market risks should be maintained to enable the system to play a substantial role in promoting ecological progress and green low-carbon development in China.

Preparation and Certification of a New Salvianolic Acid A Reference Material for Food and Drug Research

Salvianolic acid A(Sal A),a water-soluble ingredient in Danshen,has various biological activities.Sal A and its impurities have similar physical and chemical properties,as well as strong reducibility;therefore,they are difficult to prepare and purify.In this study,high-purity Sal A was obtained by purification of sephadex chromatography and preparative chromatography.Furthermore,HPLC-DAD tandem ECD and HPLC-DAD tandem MS methods were used for non-volatile organic impurity analysis,ICP-MS method was used for non-volatile inorganic impurities and mass balance method and quantitative nuclear magnetic resonance were employed to certify the product.The structures of Sal A and its relative impurities were validated by nuclear magnetic resonance spectroscopy and mass spectrometry,and their contents were quantified as well.Following the principles of ISO Guides 34:2009 and 35:2005,a Sal A reference material was certified,covering homogeneity studies,stability studies,characterization,and uncertainty estimations.

Certification and uncertainty evaluation of flavonoids certified reference materials

Flavonoids are the most widely used in the field of the food, medicine, and cosmetic due to their pharmacological functions and biological activities, such as anti-tumor, anti-inflammatory and antioxidation. This work described the assignment of purity values to 3 flavonoids certified reference materials (CRMs) including baicalein, 5,7-dihydoxy flavones and naringenine which?were developed in this study according to the ISO Guides 34 and 35. The qualitative analysis was performed by liquid chromatography-mass spectrometry (LC-MS) and infrared spectroscopy (IR). The CRMs’ purity values were assigned based on the weighted average of quantitative nuclear magnetic resonance method and mass balance approach with high resolution liquid chromatography-VWD. All the three CRMs with following value mass fractions: baicalein at a certified purity P ± U (k = 2) of 98.8% ± 0.8%;5,7-dihydoxy flavones of 99.1% ± 0.7% and naringenine of 99.5% ± 1.0% respectively. The homogeneity of the CRMs was determined by an in-house validated liquid chromatographic method. Potential degradation during storage was also investigated and a shelf-life based on this value was established.

Incentive-Driven Approach for Misbehavior Avoidance in Vehicular Networks

For efficient and robust information exchange in the vehicular adhoc network,a secure and trusted incentive reward is needed to avoid and reduce the intensity of misbehaving nodes and congestion especially in the case where the periodic beacons exploit the channel.In addition,we cannot be sure that all vehicular nodes eagerly share their communication assets to the system for message dissemination without any rewards.Unfortunately,there may be some misbehaving nodes and due to their selfish and greedy approach,these nodes may not help others on the network.To deal with this challenge,trust-based misbehavior avoidance schemes are generally reflected as the capable resolution.In this paper,we employed a fair incentive mechanism for cooperation aware vehicular communication systems.In order to deploy a comprehensive credit based rewarding scheme,the proposed rewardbased scheme fully depends on secure and reliable cryptographic procedures.In order to achieve the security goals,we used the cryptographic scheme to generate a certified public key for the authenticity of every message exchange over the network.We evaluated the friction of misbehaving vehicles and the effect of rewarding schemes in context with honest messages dissemination over the network.

Theoretical and experimental assessment of a novel method to establish the complete measurement range of the calorimeter and its limit of detection and quantification

For determining the accuracy of a calorimeter over the instrument’s entire measuring range,a novel method has been established.For this new approach,(a)benzoic acid(C_(6)H_(5)CO_(2)H) as a certified reference material(CRM),(b)SiO_(2) and(c)a mixture of CRM benzoic acid and SiO_(2) have been used.To illustrate the essential difference between 1)the novel analytical method for control of the entire measurement range and 2)the calorimeter calibration,both applications of benzoic acid(BA)have been demonstrated.An experimental result showed that BA was successfully used to check the whole calorimeter measurement range.The results also showed that the same new method was successfully applied to determine the limit of detection and quantification.A new instrument testing process and a new measurement technique have thus been established.In this way,the cost of using CRM to control the accuracy of measuring the entire measuring range of the calorimeter,as shown in this paper,is minimized.The requirements of the ISO/IEC 17025:2017 standard are satisfied.ISO/IEC 17025:2017,together with ISO 9001:2015(quality management systems),ISO 14001:2015(relate to environmental protection)and ISO45001:2018(occupational safety),constitute an integrated quality system by which a testing laboratory may also accredit.

Objective:The aim of this study was to examine the relationship between moral distress that may affect patient safety,and the clinical practice model,assessing ethical decision-making skills of certified registered nurse anesthetists(CRNAs).Methods:A survey using the Ethical Stress Scale(ESS)and the Ethical Assessment Skills Survey(EASS)was conducted with 134 CRNAs.Results:Results indicated no significant effect of practice model on level of moral distress or perceived ethical assessment skill knowledge[Wilks's lambda=0.952,F(6,256)=1.068,P=0.382,n^(2)=0.02].A statistically significant positive correlation existed between importance and skill(r=0.275,P=0.001).CRNAs felt skilled to manage the actions or activities they deemed important.Conclusion:CRNAs who perceived a higher skill level in addressing ethical issues experienced lower levels of moral distress.Findings indicate content-specific curricula for the CRNAs need to be evaluated for ethical decision-making skill assessment content.

Preference for Wood and Plastic-Based Ceiling Panels by Homeowners in Ghana： Implications for Tropical Forests Conservation and Prospects for the Local Wood Industry

This study investigated the preference for wood and plastic-based ceiling panels by homeowners in Ghana, the implications for the conservation of tropical forests and prospects for the local wood processing industry. Questionnaire was used to solicit information from 758 homeowners sampled from three cities in Ghana. The results showed that even though wood-based panels continue to enjoy strong patronage among home owners plastic-based panels appear to be the future material for ceiling. The findings suggest that, by 2030, homeowners in Ghana will use more plastic-based ceiling panels than wood-based panels, ceteris paribus. Attractiveness, durability and pleasantness are the key attributes of plastics that influence homeowners＇ decision to patronize the material. Additionally, the concern about the depletion of forest resources in Ghana has shaped homeowners decision to patronize plastic-based ceiling panels. While the shift to the use of plastic-based panels has the potential to moderate the consumption levels of timber and therefore could contribute to the conservation of tropical forests, it has a negative implication on the development of local wood processing industry. One area where manufacturers of wood products such as wood panels can explore in order to increase or maintain the market share of wood-based panel products is sourcing raw timber from certified forests.

Yield and Profit from New and Old Wheat Varieties Using Certified and Farmer-Saved Seeds

Wheat is a strategic crop for food security in Pakistan with predominance of smallholder farmers. Farmer-saved seed （FSS） is used nearly by 75% of farmers for wheat production. Frequent variety or seed replacement is uncommon even among large-scale farmers, and certified seed （CS） is mostly bought to verify the value of new varieties. Replacing old and obsolete varieties by new high yielding disease resistant varieties is key to transferring new genetic gains to farmers. For the first time in Pakistan, on-farm factorial experiments involving seven new and five old wheat varieties and their corresponding CS and FSS were conducted. A total of 49 farmers representing major wheat cropping patterns throughout the country participated in these trials in the 2014 and 2015 wheat growing seasons. Analysis of variance revealed that there was highly significant difference between wheat varieties and between seed classes. New variety ＋ CS gave 33.8% more grain yield as well as higher marginal return over farmers＇ variety ＋ FSS. Grain yield and returns from new variety ＋ FSS and farmers＇ variety ＋ CS were at par. Scientific knowledge generated in this research demonstrated that use of CS ＆new wheat varieties is best option, while growing new varieties with FSS is a second choice for the advantages accruing from their built-in genetic traits of economic importance over growing CS of old and obsolete varieties. Having more flexible seed system will help accelerate the delivery of new genetic gains to farmers＇ fields.

Procedural Sedation and Analgesia in Children in Emergency Department—Role of Adjunct Therapies

Objective: To compare sedation efficacy and parent/consultant satisfaction between standard sedation, sedation with music listening, and sedation with Certified Child life Specialists (CCLS) in children undergoing procedural sedation in the Pediatric Emergency Department (PED). Methods: Eligible children, aged 3 - 18 years, were randomly allocated to one of 3 groups: 1) standard sedation;2) sedation with music listening;3) sedation with CCLS intervention. All 3 groups received intravenous ketamine. The child life group received age appropriate comforting measures, while the music group listened to music of their choice during the procedure. The primary outcome was sedation efficacy, measured by Ramsay Sedation scale, FACES-P scale and need for re-dosing. The secondary outcome was parent/consultant satisfaction. Results: Fifty nine patients were analyzed (standard sedation: 20;sedation with music listening: 20;and sedation with CCLS: 19). There was no significant difference in mean initial ketamine dosing (1.58 ± 0.44 vs. 1.68 ± 0.36 vs. 1.42 ± 0.47, p = 0.26). There was no significant difference in median Ramsay Sedation scores [6(IQR:4,6) vs. 6 (IQR:4,6) vs. 6 (IQR:5,6)], FACES-R pain score [0 (IQR:0.0) vs. 0 (IQR:0.0) vs. 0 (IQR:0.0)] and need for re-dosing [9/20 (45%) vs. 4/20 (20%) vs. 8/19 (42.1%)] amongst the 3 groups. Parent and consultant satisfaction was high in all 3 groups. Conclusion: Our pilot study did not demonstrate a difference in sedation efficacy or parent/consultant satisfaction when adjunct therapies were used during PSA. Further studies with a large sample size are needed to define the role for such adjunct therapies during procedural sedation in PED.
