Secure communication is essential in modern embedded systems, particularly in distributed and IoT applications. This article presents a practical implementation of encrypted message exchange between ...

Starts with an initial keyword. Extends the decryption key by appending each successfully decrypted letter. Decrypts letters by performing modulo arithmetic on their positions in the alphabet. Uses ...

Background: Quantum image processing is rapidly developing in the field of quantum computing, and it can be successfully implemented on the Noisy Intermediate-Scale Quantum (NISQ) device. Quantum ...

Abstract: This paper studies the security of a recently-proposed 3D chaotic self-synchronization stream cipher. Ac­cording to the chosen-ciphertext attack, a single key decipher algorithm is further ...

Abstract: Ciphertext retrieval under heterogeneous data sets is a critical concern in the cloud-assisted Internet of Things (IoT). Previous ciphertext retrieval schemes eliminate computation burden ...

The Espressif ESP8266 chipset makes three-dollar ‘Internet of Things’ development boards an economic reality. According to the popular automatic firmware-building site nodeMCU-builds, in the last 60 ...
