Urbanisation and scientific rediscovery is increasing the demand for herbal products, whose overharvest threatens 30% of the traded species. Sustainable harvest traditions are eroding due to (a) poor prices paid to the raw drug gatherers, (b) competition between, (c) market insecurity, (d) many youth gatherers and (e) vehicular mobility to new collection areas. To revive traditions through equitable benefit sharing, Gram Mooligai (i.e. Village Herbs) Company Limited (GMCL) was established, with gatherer's groups as shareholders in Tamil Nadu state in Southern India. Sustainable Biometric experiments could not continue or help in predicting yield but participant observations and "memory harvesting" revealed that focal species have become rare amongst 25% of their earlier collection areas. Major pressures other than harvest indude (a) scarce or untimely rainfall, (b) habitat encroachments and (c) grazing. To earn more better price and sustained business demand, GMCL gatberers maximised not quantity but quality tbrougb tbumb rules ("do's and don'ts") of sustainable barvesting practices: (a) appropriate babitat area (b) maturity timing (c) less damaging methods (d) proper post-harvest treatment (e) user (buyer, co-harvester) agreements.

State Forest Departments (SFDs) of Andhra Pradesh , Karnataka , Kerala ,Tamil Nadu and Maharashtra , in consultation with FRLHT and the support of DANIIDA and UNDP have established 54 forest gene banks sites termed 'Medicinal Plant Conservation Areas (MPCA)'. The network of 54 MPCAs measuring 200 ha to 500 ha each established gradually since 1993 represents all forest types and large bio-climatic and soil regime variation. These gene banks harbour recorded populations of 45% of flowering and medicinal plants of Peninsular India , including 70% of the red listed. The intra-specific diversity i.e. germplasm conserved in the MPCA network can be used to provide authenticated quality planting material for commercial cultivation to meet rising demands of the herbal industry. MPCAs also constitute 'study sites' for threatened species recovery research. MPCAs have proved crucial in capacity building of forestry staff , local communities and researchers in the conservation of Medicinal Plants for sustainable use and equitable benefit sharing. This experience can help in implementing plans and programmes under the Biological Diversity Act 2002 , National Biodiversity Strategy and Action Plan (NBSAP) and Medicinal Plants Board.- Rediscovery of Hopea canarensis Hole (Dipterocarpaceae) - an Endemic and Little Known Species from the Western Ghats of Karnataka, India

Objective: The main intent of this research is to improve the quality-of-service in the Tor anonymous communication network by splitting the traffic and scheduling it according to the traffic load. Methods: In this manuscript, a Novel Traffic, Dividing and Scheduling (NTDS) mechanism is introduced for improving performance in the Tor anonymous communication network. The performance of the tor network is described by using various network metrics such as bandwidth, latency, jitter, loss etc. In this mechanism, the traffic load is disseminated across circuits depends on each circuit bandwidth capacity, congestion level, measured latency, throughput. Results: The Novel Traffic, Dividing and Scheduling (NTDS) mechanism show higher performance when compared to the existing router selection method. Throughput, congestion level, latency and available bandwidth are measured for the circuit and based on this the traffic is split and scheduled. If the number of nodes is 50, the packet delivery ratio is 70% in NTDS, the throughput in NTDS is 72% and end-to-end delay is 0.69. According to the comparison results, the proposed approach works better than the other existing systems with high quality-of-service. Conclusion: The findings demonstrate that the Novel Traffic, Dividing and Scheduling (NTDS) mechanism is presented and suggested that this method has high quality-of-service.Keywords

Tamil data, scripts, files needs to be preserved in computing. As there is a need for security in various computer networks fields, the paper mainly focus an algorithm in the field of secrecy , privacy, confidentiality of the documents in a computer system by the principle “ Cryptography “. Cryptography is defined as an art of security technique for computer networks. A computer user to preserve his documents, scripts needs to search for security oriented algorithms, packages, databases which arises an unfulfilled thirst. To quench the security thirst, a recent algorithm namely ‘Elliptic Curve Cryptography (ECC)’ is framed as it is an approach to public-key cryptography based on some algebraic structure of elliptic curves over finite fields. The creator keeps the knowledge of security key mechanisms such as private key, public keys. The keys which are generated best choose random-numbers that uses products of two large prime numbers as the key. Any user to preserve his documents picks two large random primes as his private key, and publishes the product as his public key. The public key based algorithm ‘Elliptic Curve Cryptography (ECC)’ is based on the creation of different keys that are difficult to solve without certain knowledge about how they were created. Elliptic curve cryptosystems is computationally efficient than the first generation public key systems such as RSA and Diffie-Hellman algorithms as the report says. As an added advantage the paper mainly focus on ECC based security algorithms for Tamil document privacy. The document related in Tamil words are analyzed commonly as a process which includes security mechanisms that emerges finally in the system as a preserved document.Keywords

As mobile networks expand their bandwidth, mobile phones, as with any other Internet device, become substantially exposed to Internet security vulnerabilities. Public key cryptography is a primary concept in implementing wireless device security. This paper describes the applicative use of PKI in current and future mobile phone applications, and shows how the standard-compliant implementation of cryptographic algorithms, enables wireless devices to become PKI-enabled. The Wireless Application Protocol is a leading technology for companies trying to unlock the value of the Mobile Internet. The WAP model introduces a Gateway that translates between WAP and Internet protocols. This Gateway is typically located at the site of the mobile operator, although sometimes it may be run by an application service provider or enterprise. WAP enables such capability via use of a crypto API, referred to as the WMLScript Crypto API. WMLScript is a simple script language that allows client-side processing, and instructs the client device to invoke application-level functions.Keywords

Security in digital communications nowadays depends on cryptography. Multiparty Key Access depends on algorithms for generating asymmetric keys. The present algorithmic rule in use is MKA that uses mathematical properties of prime numbers and therefore the quality of resolving giant numbers to come up with secure asymmetric keys. A more modern algorithmic rule that might be used is Elliptic Curve Cryptography (ECC). Elliptic Curves have mathematical properties in which specified uneven keys is generated which is stronger than those created by Existing strategies. To investigate the utilization of ECC for MKA, a basic ECC generator is used and it will generate live keys and coding durations. The comparative key strength of ECC and Existing strategies is taken into thought; ECC is orders of magnitude quicker than Existing strategies for a similar security. The problems preventing the adoption of ECC using MKA in Cryptography area for raising security unit mentioned. The properties rights of ECC are utilized in MKA, the biggest obstacle to ECC adoption are substitution the present MKA infrastructure that uses Existing strategies. It is expected that ECC in MKA can become customary by 2020.Keywords

Aiming to develop an e-market, need to consider not only technological, but also business issues that might affect their acceptance and profitability. By describing an example of an e-market application, this paper discusses these issues and shows that although technology may provide various different solutions for the development of an e-market, it cannot on its own lead to an e-market’s success. During the last decade e-commerce has quickly evolved through a succession of business models. The commercially operational business sites in eleven categories: e-shop, e-auction, e-procurement, e-mall, third party marketplace, virtual communities, value chain service provider, value chain integrator, collaboration platform, information brokerage and trust. However, that the Internet economy has divided the overall market space into three broader structures: Portals, Market Makers, and Product Service providers. A portal engages primarily in building a community of users seeking information about products and services. A market maker plays a similar role with that of a portal in building a community of buyers, customers. A community of suppliers of products and services. However, market makers differ from portals in that they provide, handle and facilitate the business transaction that takes place between the buyer and the supplier. Last but not least, the product, service providers are dealing directly with their customers when it ultimately comes to the business transaction. These three structures incorporate various business models or different definitions. For example, a market maker is similar to an e-mall, a third party marketplace, an e-marketplace or an e-market. For reasons of clarity, in this paper, define our application by using the term “e-market”. E-markets have evolved and become important elements in the Internet-age economy. The main functionality of an electronic market is to match seller offerings with buyer preferences.Keywords

A random search through a finite but large key space is not usually an acceptable cryptanalysis approach. The focus of this work is on the use of a genetic algorithm (GA) to conduct a directed search in a key space. The structure of Lucifer was significantly altered and since the design rationale was never made public and the secret key size was reduced from 128-bit to 56-bits this initially resulted in controversy, and some distrust among the public. In this paper, a new method has been developed for the first time to break DES like examples. These examples include both DES with eight rounds. The performance of the proposed method, as such, is considerably faster than exhaustive search and differential cryptanalysis. Therefore, it can be directly applied to a variety of DES like systems instead of the current techniques. Here, a Genetic Algorithm, GA, is proposed for the cryptanalysis is of DES like systems to find out the underlying key. The genetic algorithm approach is adopted, for obtaining the exact key by forming an initial population of keys that belong to the key subspace. In the proposed algorithms, the premature convergence could be avoided by dynamic variation of control parameters that can affect the fitness function. DES uses a 56-bit encryption key. The key size was apparently dictated by the memory and processing constraints imposed by a single-chip implementation of the algorithm for DES. The key itself is specified with 8 bytes, but one bit of each byte is used as a parity check.

In this paper, we first identify some unique design requirements in the aspects of security and TESLA for communication between different communication devices in vehicular ad hoc networks. We propose a Time-Efficient stream Loss -Tolerant Authentication broadcast authentication protocol based on Group signature and Identify (ID) based signature techniques. We demonstrate that the proposed protocol as an efficient protocol with communication and computation overhead, which scales to large number of receiver, and tolerate packet loss. TESLA protocol guarantee the requirements of security can provide the desired traceability of each vehicle in the case where the ID of the message sender has to be receiver by the authority of any dispute event Extensive simulation is conducted to verify the efficiency, effectiveness and applicability of the proposed protocol in various application scenarios under different road systems.Keywords

Hexavalent chromium is one the most important water pollutants. There are a number of available technologies used for the remediation of chromium, but none of them is applicable to all situations. In this study a hybrid method of coagulation-flocculation uses Moringa oleifera seed coagulant polymer and adsorption-fine filtration with composite of kaolinite clay and sand media for removing chromium ions present in aqueous systems. 98% of chromium ions were removed from the water by this novel technique of coagulation-flocculation and adsorption-filtration process.Keywords

Virtualized infrastructure in cloud computing has become an attractive target for cyber attackers to launch advanced attacks. This paper proposes a novel big data based security analytics approach to detecting advanced attacks in virtualized infrastructures. Network logs as well as user application logs collected periodically from the guest virtual machines (VMs) are stored in the Hadoop Distributed File System (HDFS). Then, extraction of attack features is performed through graph-based event correlation and Map Reduce parser based identification of potential attack paths. Next, determination of attack presence is performed through two-step machine learning, namely logistic regression is applied to calculate attack’s conditional probabilities with respect to the attributes, and belief propagation is applied to calculate the belief in existence of an attack based on them. Experiments are conducted to evaluate the proposed approach using well-known malware as well as in comparison with existing security techniques for virtualized infrastructure. The results show that our proposed approach is effective in detecting attacks with minimal performance overhead.Keywords
