Handbook of SCADA/Control Systems Security

The provision and protection of many providers we depend upon—including water remedy, electrical energy, healthcare, transportation, and monetary transactions—are commonly positioned in danger by way of cyber threats. The instruction manual of SCADA/Control platforms safety is a primary define of defense suggestions, methodologies, and suitable details referring to the supervisory keep an eye on and knowledge acquisition (SCADA) structures and know-how that quietly function within the history of severe software and business amenities around the world.

Many QKD protocols [1, 2, 3] have been put forward constantly since Bennett and Brassard proposed BB84 protocol [4] in 1984. , the two legitimated parties first create a shared private key, and then use it to encrypt the transmitted messages. On the other hand, the nondeterministic property in the standard QKD scheme leads loss of lots of qubits since many qubits have to be discarded. As far as communication is concerned, this beforehand step and loss of many qubits undoubtedly reduce the efficiency of communication.

C) Copy the ImageInfo (First 54 byte) of the Header from Input 24-Bit Bmp file to a newly created BMP file and edit this Header by changing filesize, Bit Depth, Colors to confirm to 8-Bit BMP. d) Copy the ColorTable from a sample gray scale Image to this newly created BMP at 54th Byte place on words. 114*blueValue); 36 D. Bhattacharyya et al. 114*blueValue); grayValue = blueValue = greenValue = redValue; Write to new BMP file. Take 24-bit BMP color image as input. Then convert it to 8-bit Gray Scale image by following this algorithm.

She tells Bob which basis has been used for the measure¯ CB and |M |M ment. Then, Bob makes use of Alice’s basis to measure WB-sequence and CA¯ W B and |M ¯ CA . Finally, Alice and Bob sequence and gets the outcomes |M gather together to compare their measurement outcomes. If no eavesdropping exists, their measurement outcomes should satisfy the following conditions 2 2 ¯ W B , |M ¯ CA = |M ¯WA . ¯ CB = |M |M (9) In the message mode, Alice and Bob perform the proper d-dimensional BM to measure the particle pairs (DA-EB)-sequence (composed of DA-sequence and EB-sequence) and (DB-EA)-sequence (composed of DB-sequence and EAsequence) to exchange their secret messages as the proposed processes inthe Bidirectional Quantum Secure Direct Communication 47 message mode of the two-dimension system.
