SummaryCAIAF2011D. E. SimosPrivate-KeyCryptosystemsCryptanalysisConclusionHighlights1 We constructed private-key block ciphers from combinatorialdesigns (Hadamard matrices and Plotkin arrays).2 We presented a cryptanalysis for Hadamard and Plotkin cipherswhich showed that the ciphers are secure against cryptographicattacks in most cases.3 We conducted a simulation of brute-force attacks for KroneckerPlotkin ciphers, proving the security of these ciphers.Future WorkDevelop a public-key cryptosystem based on similar properties ofcombinatorial designsConsider more types of cryptographic attacksImplement the Hadamard and Plotkin ciphers for hardware-usedcryptography purposes (i.e. Military, Intelligence Services)24 / 26
