A formally verified decentralized key management architecture for wireless sensor networks [PDF]
, 2003 We present a decentralized key management architecture for wireless sensor networks, covering the aspects of key deployment, key refreshment and key establishment. Our architecture is based on a clear set of assumptions and guidelines.

Advancing Cryptographic Security With a New Delannoy-Derived Chaotic S-Box
IEEE AccessThe S-Box (Substitution Box) plays a crucial role in cryptographic security by introducing non-linearity and confusion into the encryption process. It enhances the resistance against cryptanalytic attacks, such as differential and linear cryptanalysis ...

A Secure and Efficient Authentication Mechanism Applied to Cognitive Radio Networks
IEEE Access, 2017 Cognitive radio (CR) has been introduced to accommodate the steady increment in the spectrum demand. Wireless security in CR network (CRN) is a challenging technical area due to the dynamic and unique characteristics of CRNs.

Symmetric extension in two-way quantum key distribution
, 2009 We introduce symmetric extensions of bipartite quantum states as a tool for analyzing protocols that distill secret key from quantum correlations. Whether the correlations are coming from a prepare-and-measure quantum key distribution scheme or from an ...

Tree Parity Machine Rekeying Architectures [PDF]
, 2005 The necessity to secure the communication between hardware components in embedded systems becomes increasingly important with regard to the secrecy of data and particularly its commercial use. We suggest a low-cost (i.e.

Symmetric Key Encryption Based on Rotation-Translation Equation
Symmetry, 2020 In this paper, an improved encryption algorithm based on numerical methods and rotation–translation equation is proposed. We develop the new encryption-decryption algorithm by using the concept of symmetric key instead of public key.

Owner Specified Excessive Access Control for Attribute Based Encryption
IEEE Access, 2016 Attribute-based encryption (ABE) has emerged as a promising solution for access control to diverse set of users in cloud computing systems. Policy can just specify whether (or not) any specific user should be given access to data, but it lacks to provide

3D CUBE Algorithm for the Key Generation Method: Applying Deep Neural Network Learning-Based
IEEE Access, 2020 Current encryption systems are run with a hybrid mode in which symmetric and asymmetric key methods are mixed. This hybrid mode is devised to employ the fast processing speed of the symmetric key while circumventing the difficulty of providing services ...

Enhanced RC5 Algorithm using Parallel Computing for Communication Networks
Ingeniería y Ciencia, 2019 One of the main disadvantages of symmetric key algorithms in comparison with asymmetric key ones is their lower security level due to their shorter key length.

Strong wavefront lemma and counting lattice points in sectors
, 2007 We compute the asymptotics of the number of integral quadratic forms with prescribed orthogonal decompositions and, more generally, the asymptotics of the number of lattice points lying in sectors of affine symmetric spaces.
