Survey, Analysis and Re-evaluation -- How Efficient and Secure a Mix Network Can Be
Found in: Computer and Information Technology, International Conference on
By Kun Peng
Issue Date:September 2011

The recent shuffling schemes usually claim strong security and much higher efficiency than their predecessors. In this paper, it is illustrated that some of them are not so secure as they claim. Some of them are incomplete in correctness and may fail even ...
Self-Calibration of Catadioptric Camera with Two Planar Mirrors from Silhouettes

By Xianghua Ying, Kun Peng, Yongbo Hou, Sheng Guan, Jing Kong, Hongbin Zha
Issue Date:May 2013
pp. 1206-1220
If an object is interreflected between two planar mirrors, we may take an image containing both the object and its multiple reflections, i.e., simultaneously imaging multiple views of an object by a single pinhole camera. This paper emphasizes the problem ...
Investigation and Survey of Secret Sharing in Verifiable Distributed Systems

By Kun Peng
Issue Date:October 2011
pp. 342-347
The two most recent PVSS (publicly verifiable secret sharing) schemes are illustrated to be vulnerable to a simple attack. Moreover, one of them has to deteriorate its efficiency greatly to meet practical security requirement. The attack makes the share ho...
Secure E-Commerce Based on Distributed Processing

Improving Applicability, Efficiency and Security of Non-Membership Proof
Found in: Data, Privacy, and E-Commerce, International Symposium on
By Kun Peng, Feng Bao
Issue Date:September 2010
pp. 39-44
Two new non-membership proof protocols are proposed in this paper, which prove that a committed message is not in a finite set. They are concrete proof protocols rather than abstract principles. The first is a completely general non-membership proof suitab...
Efficient Proof of Validity of Votes in Homomorphic E-Voting
Found in: Network and System Security, International Conference on
By Kun Peng, Feng Bao
Issue Date:September 2010
pp. 17-23
A special membership proof technique is applied to the efficiency bottleneck of homomorphic e-voting, vote validity check. Although the special membership proof technique has some limitations such that so far few appropriate applications have been found fo...
Single View Metrology Along Orthogonal Directions
Found in: Pattern Recognition, International Conference on
By Kun Peng, Lulu Hou, Ren Ren, Xianghua Ying, Hongbin Zha
Issue Date:August 2010
pp. 1658-1661
In this paper, we describe how 3D metric measurements can be determined from a single uncalibrated image, when only minimal geometric information are available in the image. The minimal information just is orthogonal vanishing points. Given such limited in...
An Efficient Range Proof Scheme

A Shuffling Scheme with Strict and Strong Security
Found in: Emerging Security Information, Systems, and Technologies, The International Conference on
By Kun Peng, Feng Bao
Issue Date:July 2010
pp. 201-206
In this paper, it is pointed out that security of no existing shuffling scheme is strong enough for their supposed applications. For example, some of them are not always correct. Especially, their soundness and privacy depend on hardness of certain mathema...
Geometric properties of multiple reflections in catadioptric camera with two planar mirrors
Found in: Computer Vision and Pattern Recognition, IEEE Computer Society Conference on
By Xianghua Ying, Kun Peng, Ren Ren, Hongbin Zha
Issue Date:June 2010
pp. 1126-1132
A catadioptric system consisting of a pinhole camera and two planar mirrors is deeply investigated in this paper. The two mirrors combine to form a corner and face-to-face with the pinhole. Their relative pose is unknown. An object will be reflected in the...
Achieving High Efficiency in Membership Proof without Compromising or Weakening any Security Property
Found in: Computer and Information Technology, International Conference on
By Kun Peng, Feng Bao
Issue Date:July 2010
pp. 1044-1049
Membership proof shows that a secret committed message is in a finite set. In this paper, a general, flexible, universally verifiable and efficient solution to membership proof is proposed. It overcomes the drawbacks of the existing membership proof scheme...
