Expanded into two volumes, the Second Edition of Springer's Encyclopedia of Cryptography
and Security brings the latest and most comprehensive coverage of the topic: Definitive …

Recently it was observed that for a particular nonzero input difference to an S-Box, some bits
in all the corresponding output differences may remain invariant. These specific invariant …

Printed documents are still relevant in our daily life and information in it must be protected
from threats and attacks such as forgery, falsification or unauthorized modification. Such …

Noncryptographic hash functions have an immense number of important practical
applications owing to their powerful search properties. However, those properties critically …

Abstract In 1994, Peter Shor published a quantum algorithm capable of factoring large
integers and computing discrete logarithms in Abelian groups in polynomial time. Since …

Dealing with digital medical images is raising many new security problems with legal and
ethical complexities for local archiving and distant medical services. These include image …

We present a method to iteratively construct new bent functions of n+ 2 variables from a bent
function of n variables and its cyclic shift permutations using minterms of n variables and …

We give some attacks on the DBL hash modes MDC-4 and MJH. Our preimage attack on the
MDC-4 hash function requires the time complexity O (2 3n/2) for the block length n of the …

We first give a proof of an isomorphism between the group of affine equivalent maps and the
automorphism group of Sylvester Hada-mard matrices. Secondly, we prove the existence of …

Collect and analyse threat models to the Bitcoin ecosystem and its software. The create
misuse case, attack trees, and sequence diagrams of the threats. Create a malicious client …
