A new block cipher for gray images is proposed in this paper which fully utilizes whole set of DNA complementary rules dynamically for encoding and decoding each pixel of a block. The most significant (MSB) part of each block is added under DNA addition operation with least significant (LSB) while LSB part itself get encrypted by chaotically selecting(More)
Radio frequency identification (RFID) is getting popularity among identification technologies owing to its low cost, light weight, reduced size and inexpensive maintenance. Due to the recognition of RFID in the area of manufacturing, retail, pharmaceuticals and logistics, it is now in consideration for use in many different areas like ubiquitous computing,(More)
In the existing agriculture, critical decisions related to irrigation, fertilization and pesticides management are often left to farmers' discretion. They use irrelevant fertilizers and pesticides, and perform improper irrigation, which may lead disastrous effects on their crops. Different approaches have been proposed to enhance the Eco-sustainable(More)
In this paper we have present the architecture and module for internet firewall. The central component is fuzzy controller while properties of packets are fuzzified as inputs. On the basis of proposed fuzzy security algorithm, we have figured out security level of each packet and adjust according to packets dynamic states. Internet firewall can respond to(More)
Presently employed Internet Protocol (IP) stack possesses number of architectural problems. The contemporary research direction for the improvement of present Internet architecture mainly focuses on the use of real identifiers instead of IP addresses for host identification in the network. However, the proposed architectures mostly discuss the(More)
A novel image encryption algorithm in streaming mode is proposed which exhaustively employs an entire set of DNA complementary rules alongwith one dimensional chaotic maps. The proposed algorithm is highly efficient due to encrypting the subset of digital image which contains 92.125 % of information. DNA addition operation is carried out on this MSB part.(More)
