Stream ciphers are an important class of symmetric cryptographic algorithms. The eSTREAM project contributed significantly to the recent increase of activity in this field. In this paper, we present a survey of the eSTREAM project. We also review recent time/memory/data and time/memory/key trade-offs relevant for the generic attacks on stream ciphers.

Developments in data streams, coupled with the growth in mobile and pervasive devices, have led to the emergence of Ubiquitous Data Mining (UDM). UDM aims to perform data stream mining in a ubiquitous environment with resourceconstrained and/or mobile devices. Over the past few years, stream mining techniques have attracted the attention of the data mining community. However these techniques ha...

Privacy-preserving estimation of counts items in streaming data finds applications several real-world scenarios including word auto-correction and traffic management applications. Recent works RAPPOR [1] Apple's count-mean sketch (CMS) algorithm [2] propose privacy preserving mechanisms for count large volumes using probabilistic structures like counting Bloom filter CMS. H...

in this paper, river regime equations through developing of unit stream power equation and based on data of sistan and karaj rivers were derived. at the first step, methods and out-comes of former researchers are classified. on the next step, based on dimensional analysis, unit stream power as a function of river flow parameters including suspended sediment load and specific gravity of particle...

commonly used environmental flow evaluation techniques range in complexity. some requires stream flow records alone, and some accounts for the habitat requirements of individual species life-stages and physical characteristics of the stream. hydrological based methods for environmental flow assessment are the first step in planning for environmental allocation in developing countries. for deter...

assiganga stream is an important tributary of bhagirathi river in central himalaya (india). the stream is characterized by heterogeneity in habitat and substratum features harboring diverse fish fauna. at present this stream is facing threat of being fragmented by the construction of two hydro-electric projects. present study aimed to study fish diversity and their habitat use in assiganga stre...
