Matrix Affine CipherIn this cryptosystem, we have presented a novel technique for security of video data by using matrix affine cipher (MAC) combined with two-dimensional discrete wavelet transform (2D-DWT). Existing schemes for security of video data provides only one layer of security, but the...

I've got following code I want to execute the query first and then return result. How should I do it. I've also done it with simple for loop but does not work. I think you just need to call next() aft... what is the difference between \c and \\c?

Even the COPACOBANA (Cost-Optimized Parallel Code Breaker) machine can break such an algorithm in less than a day, and its computational power is up to 64 bits [26]. Jack, in [27], breaks down the Hill cipher for 𝑛=2n=2 with an IBM 650 machine, and finds it impractical and ...
