Physical Unclonable Functions(PUFs)can be seen as kind of hardware one-way functions,who are easily fabricated but difficult to clone,duplicate or ***,PUFs with unclonable and unpredictable properties are welcome to be applied in designing lightweight cryptography *** this paper,a Basic key Distribution Scheme(Basic-kDS)based on PUFs is firstly ***,by employing different deployment modes,a Random Deployment key Distribution Scheme(RD-kDS)and a Grouping Deployment key Distribution Scheme(GD-kDS)are further proposed based on the Basic-kDS for large scale wireless sensor *** our proposals,a sensor is not pre-distributed with any keys but will generate one by the embedded PUF when receiving a challenge from the gateway,which provides perfect resilience against sensor capture ***,the unclonable and unpredictable properties of PUF guarantee the key uniqueness and two-way *** and experiment results show that our proposals have better performances in improving the resilience,secure-connectivity,and efficiency as compared to other schemes.

In Shamir’s(t,n) threshold of the secret sharing scheme, a secret is divided into n shares by a dealer and is shared among n shareholders in such a way that (a) the secret can be reconstructed when there are t or more than t shares;and (b) the secret cannot be obtained when there are fewer than t shares. In the secret reconstruction, participating users can be either legitimate shareholders or attackers. Shamir’s scheme only considers the situation when all participating users are legitimate shareholders. In this paper, we show that when there are more than t users participating and shares are released asynchronously in the secret reconstruction, an attacker can always release his share last. In such a way, after knowing t valid shares of legitimate shareholders, the attacker can obtain the secret and therefore, can successfully impersonate to be a legitimate shareholder without being detected. We propose a simple modification of Shamir’s scheme to fix this security problem. Threshold cryptography is a research of group-oriented applications based on the secret sharing scheme. We show that a similar security problem also exists in threshold cryptographic applications. We propose a modified scheme to fix this security problem as well.

加拿大农业的历史只有３００多年，随着农业技术的进步和生产的发展，环境退化问题如土壤侵蚀、压实、盐渍化、有机质下降、水质污染等已引起了极大的关注。８０年代中期直至９０年代，农业的重点开始向持续性转移，持续农业是以确保农业生产高产和安全的同时以满足经济、社会以及环境的需求为目标。重点论述了加拿大农业生产中，尤其是半干旱草原地区土壤的环境问题，以及有关的农业持续性发展对策。

Unconditionally Secure Multi-Secret Sharing Scheme

以科研成果促进测绘实践教学升级的探索与实践

2012 IEEE International Conference on Computer Science and Automation Engineering（CSAE 2012）

作者： lein Harn Department of Computer Science Electrical Engineering University of Missouri-kansas City

In Shamir’s（t,n）secret sharing（SS）scheme,a master secret s is divided into n shares by a dealer and is shared among n shareholders in such a way that any t or more than t shares can reconstruct this master secret;but fewer than t shares cannot obtain any information about the master secret *** Shamir’s scheme is unconditionally secure,it unfortunately requires a large data expansion（i.e.,t shares are needed to reclaim one secret）.Therefore,Shamir’s scheme is inefficient as a conveyor of ***-secret sharing（MSS）scheme,which allows multiple master secrets to be shared among shareholders,has been proposed to improve the efficiency of Shamir’s ***,all existing MSS schemes are computationally *** this paper,we propose an unconditionally secure MSS scheme based on Shamir’s *** proposed MSS scheme allows each shareholder to keep only one private share and uses it to share t master secrets.
