Often the S-boxes are the only nonlinear components in a block cipher and as such play an
important role in ensuring its resistance to cryptanalysis. Cryptographic properties and …

For engineering applications that are based on nonlinear phenomena, novel information
processing systems require new methodologies and design principles. This perspective is …

Abstract The Russian Federation's standardization agency has recently published a hash
function called Streebog and a 128-bit block cipher called Kuznyechik. Both of these …

The goal of this paper is to improve the efficiency and applicability of straightline extraction
techniques in the random oracle model. Straightline extraction in the random oracle model …

This paper describes the state of the art for cryptographic hash functions. Different definitions
are compared, and the few theoretical results on hash functions are discussed. A brief …

The question if there exist nonnormal bent functions was an open question for several years.
A Boolean function in n variables is called normal if there exists an affine subspace of …

Among those cryptographic hash function which are not based on block ciphers, MD4 and
Snefru seemed initially quite attractive for applications requiring fast software hashing …

User authentication is a critical aspect of any information exchange system which verifies the
identities of individuals seeking access to sensitive information. Conventionally, this …

Elliptic curve cryptography (ECC) is a relatively newer form of public key cryptography that
provides more security per bit than other forms of cryptography still being used today. We …
