Utilization of secret sharing technology for secure communication: a state-of-the-art review

Secret Sharing-Based IoT Text Data Outsourcing: A Secure and Efficient Scheme

“…Different from text data outsourcing, applications with massive amounts of images have faced memory space issues with Shamir's scecret sharing scheme due to the N times of share size (of the images) required. For efficiency consideration, another secret sharing scheme, called ramp secret sharing (or multi-secret sharing) has therefore been utilized to replace Shamir's secret sharing scheme for outsourcing image datasets [20], [21]. More precisely, as compared with Shamir's (k, N )threshold secret sharing scheme, an ( , k, N ) ramp secret sharing scheme reduces the share size by 1 times at the sacrifice of security level though (which can be improved by incorporating an additional security solution such as permutation, stenography, matrix projection, etc..) [21].…”

Cognitive Covert Traffic Synthesis Method Based on Generative Adversarial Network

“…In recent years, the use of traffic camouflage, channel invisibility, and other means of covert communication has become a hot spot of network countermeasures. Network covert communication refers to the violation of communication restriction rules in the network environment [1,2], which makes some network resources in the network protocol that are not used for communication have the ability to transfer information [3], so as to avoid review and supervision. The existing network covert communication is based on the prisoner's dilemma model in narrow sense, and the related research can be divided into three aspects, namely, symbol design [4,5], channel coding [6][7][8], and channel optimization [9].…”

“…(1) At the model level, the traditional covert communication only focuses on the machine detection rules, without the cognitive modeling of human sensory abnormalities, which is difficult to resist the cognitive review of "human in the system." This is a blank in the model of covert communication (2) At the algorithm level, the information carrying of traditional covert communication is the explicit intervention and modulation of symbols, so it is necessary to write a fixed covert algorithm, which leads to poor diversity of covert channel and weak antianalysis ability…”

“…(1) The paper proposes a "cognitive deception" method, improves the narrow-sense prisoner model, establishes a cognitive game framework of covert confrontation, and realizes a new paradigm of covert communication game (2) In this paper, a Wasserstein Generative Adversarial Network of Covert Channel (WCCGAN) model is proposed. By defining the activity loss function of traffic and the application loss function of protocol, the cognitive equivalent mechanism is established to effectively constrain the prediction space of the model, and the adaptive generation of covert traffic is realized The rest of this paper is organized as follows: Section 2 introduces the related work.…”
