Abstract:The multicast authentication protocol namely MABS including two schemes MABS-B and MABS-E. The basic scheme (MABS-B) eliminates packet loss and also efficient in terms of latency computation and communication overhead due to effective cryptographic primitive called batch signature which authenticates any number of packets simultaneously. This paper deals with the enhanced scheme (MABS-E) which combines the basic scheme with a packet filtering mechanism to alleviate DOS impact. The file list is displayed in both sender and the receiver but the file content is present in the sender only. The receiver request the file content by sending the file name then the sender verify the request if the receiver is authentic. Then sender splits the file content into packets and signs each packet by generating the key then encrypts the packets and sends to the receiver. The receiver verifies the packets and then decrypts the message using sender's public key.

Abstract:This paper proposes to study the alternatives for the rural population of the southern Brazil, in these beginning of the XXI century. When forestry is implemented we can observe the degradation of quality of life indicators (health, education and income). The multi activity of the small producer is replaced for the so called culture of abandonment. The issues addressed in this study are (i) is forestry an activity that leads to the impoverishment of the region? (ii) does the traditional economic activity causes the region's wealth? and (iii) will the southern Brazil be "reached" by forestry? To answer these questions the hypotheses formulated are (i) there is an inverse relationship between the HDI and forestry, (ii) There is a direct relationship between traditional economic activity and forestry, and (iii) Forestry is replacing the traditional economic activity. Data analysis showed is not possible to study the production in an aggregated manner.
Keywords: Economic activity, alternatives to forestry, smallholders.

Abstract:Market Basket Analysis is the general name for understanding product purchase patterns at the customer level in the super market. This paper focuses on clustering similar and frequent item sets using an integrated approach of SOM and K-Means clustering techniques. The proposed algorithm finds the number of clusters using Artificial Neural Network (SOM) and then groups the similar item sets into the respective clusters using the k-means to improve the marketing campaign.
Keywords: Clustering; k-means; SOM
