Internet of Things (IoT) is an emergent and evolving technology, interconnecting the cyber
and physical worlds. IoT technology finds applications in a broad spectrum of areas such as …

We improve the attack of Durak and Vaudenay (CRYPTO'17) on NIST Format-Preserving
Encryption standard FF3, reducing the running time from O (N^ 5) O (N 5) to O (N^ 17/6) O …

Small block sizes may lead to the information leakage of plaintext due to the cipher block
repetition in the block cipher! s ECB or CBC mode. This paper presents an innovative block …

Concealing a message in the APPn markers of a JPEG image not only protects the security
of the message but also induces no change to the quality of the image. However, from the …

In this paper, we present a generic framework for decomposing block cipher structure with
secret components. The generic framework is based on the zero-correlation linear …

The standard view of cryptography is that secure systems should be built by implementing
known primitives whose theoretical security guarantees are well understood. In this work we …

Cryptography studies secure communications. In symmetric-key cryptography, the
communicating parties have a shared secret key which allows both to encrypt and decrypt …
