METHOD OF XOR HOMOMORPHIC ENCRYPTION AND SECURE CALCULATION OF A HAMMING DISTANCEThe invention concerns a method for encrypting a binary data item characterised in that it comprises the steps consisting of: —generating a public key and a private key, the public key being a sparse matrix ...
We settled on an answer based on another crypto 101 concept: The unicity distance. This is the minimum number of ciphertext characters such that the expected number of possible plaintexts is exactly 1; we simply plugged in the given ciphertext length and solved for the key length instead. ...
Distance algorithm that used in flight numbers similarity calculation on the basis of Levenshtein Distance which used in text similarity quantitative comparison.It proved that this method is feasible by the actual data calculation of Beijing control area.And then we calculate the average similarity of ...
The error correction capacity is not reduced in the scheme of Fu et al., but the secret image is recovered by directly aligning the two shadows to perform the calculation, so when an offset, damage or other noise occurs, robustness will be very poor. The robustness aspect was not mentioned...
The operators\(X_i^{(\alpha )}\)satisfy some useful properties. Firstly, they are self-adjoint by construction with eigenvalues\(\pm 1\). From this, or from direct calculation, it follows that $$\begin{aligned} \left( X_i^{(\alpha )}\right) ^2&= \left( Q_i^{(\alpha )}\rig...

The mathematical formula for the calculation of information entropy is: $$\begin{aligned} H(m)=\sum _{i=0}^{2^{N}-1} p\left( m_{i}\right) \log \frac{1}{p\left( m_{i}.\right) } \end{aligned}$$ (15) where \(p(m_i)\) represents the probability of \(m_i\). and...
