The conference was originally planned to take place in Vienna, Austria, and changed to an online event due to the COVID-19 pandemic. The 25 full and 3 short papers presented in these proceedings were carefully reviewed and selected from 85 submissions. They were organized in topical sections as follows: Encryption; signatures; cryptographic schemes and protocols; attacks and counter-measures; and attestation and verification. 410 0$aSecurity and Cryptology,$x2946-1863 ;$v13099 606 $aCryptography 606 $aData encryption (Computer science) 606 $aApplication software 606 $aSoftware engineering 606 $aComputer networks 606 $aComputer vision 606 $aCoding theory 606 $aInformation theory 606 $aCryptology 606 $aComputer and Information Systems Applications 606 $aSoftware Engineering 606 $aComputer Communication Networks 606 $aComputer Vision 606 $aCoding and Information Theory 615 0$aCryptography. 615 0$aData encryption (Computer science) 615 0$aApplication software. 615 0$aSoftware engineering. 615 0$aComputer networks. 615 0$aComputer vision. 615 0$aCoding theory. 615 0$aInformation theory. 615 14$aCryptology. 615 24$aComputer and Information Systems Applications. 615 24$aSoftware Engineering. 615 24$aComputer Communication Networks. 615 24$aComputer Vision. 615 24$aCoding and Information Theory. 676 $a005.824 702 $aStevens$b Marc 702 $aConti$b Mauro 702 $aKrenn$b Stephan 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910768472303321 996 $aCryptology and Network Security$92968064 997 $aUNINA
