Hierarchial Secret Sharing in Ad Hoc Networks through Birkhoff Interpolation
نویسندگان
چکیده
Securing ad hoc networks represents a challenging issue, related to their very characteristics of decentralized architecture, low-complexity, and multiple hops communications. Even if several methods are available, this paper presents a novel approach to allow secret sharing of information at lower levels of the node protocol stack. In fact, secret sharing schemes provide a natural way of addressing security issues in ad hoc networks. To this aim, a flexible framework for secure end-to-end transmission of confidential information is proposed which exploits multipath source routing and hierarchical shares distribution. Such a goal is achieved by designing an ideal, perfect, and eventually verifiable secret sharing scheme based on Birkhoff polynomial interpolation and by establishing suitable hierarchies among independent paths.

متن کاملDynamic and Verifiable Hierarchical Secret Sharing
In this work we provide a framework for dynamic secret sharing and present the first dynamic and verifiable hierarchical secret sharing scheme based on Birkhoff interpolation. Since the scheme is dynamic it allows, without reconstructing the message distributed, to add and remove shareholders, to renew shares, and to modify the conditions for accessing the message. Furthermore, each shareholder...
متن کاملIdeal social secret sharing using Birkhoff interpolation method
The concept of social secret sharing was introduced in 2010 by Nojoumian et al. In Nojoumian et al.’s scheme (called SSS), the number of shares allocated to each party depends on the player’s reputation and the way he interacts with other parties. In other words, weights of the players are periodically adjusted such that cooperative participants receive more shares compared to non-cooperative p...
