Digital signatures are an important mechanism for ensuring data trustworthiness via source authenticity, integrity, and source nonrepudiation. However, their trustworthiness guarantee can be subverted in the real world by sophisticated attacks, which can obtain cryptographically legitimate digital signatures without actually compromising the private signing key. This problem cannot be adequately addressed by a purely cryptographic approach, by the revocation mechanism ...

A new approach to digital image signatures (watermarks) is proposed in this study. An image signature algorithm consists of two stages : signature casting and signature detection. In the first stage, small changes are embedded in the image which afterwards are identified in the second stage. After chosing certain pixel blocks from the image, a constraint is embedded among their ...

We consider the problem of broadcasting sensitive information to many low cost receivers when the authenticity and integrity of the received messages are the determining factors but secrecy is not important. Although several methods exist to authentify information, as a rule, they lack the asymmetry the transmission system itself exhibits. Therefore, we propose a highly non- symmetric algorithm to generate ...

Digital signatures are an important mechanism for ensuring data trustworthiness via source authenticity, integrity, and source nonrepudiation. However, their trustworthiness guarantee can be subverted in the real world by sophisticated attacks, which can obtain cryptographically legitimate digital signatures without actually compromising the private signing key. This problem cannot be adequately addressed by a purely cryptographic approach, by the revocation mechanism of Public Key Infrastructure (PKI) because it may take a long time to detect the compromise, or by using tamper-resistant hardware because the attacker does not need to compromise the hardware. This problem will become increasingly more important and evident because of stealthy malware (or Advanced Persistent Threats). In this paper, we propose a novel solution, dubbed Assured Digital Signing (ADS), to enhancing the data trustworthiness vouched by digital signatures. In order to minimize the modifications to the Trusted Computing Base (TCB), ADS simultaneously takes advantage of trusted computing and virtualization technologies. Specifically, ADS allows a signature verifier to examine not only a signature's cryptographic validity but also its system security validity that the private signing key and the signing function are secure, despite the powerful attack that the signing application program and the general-purpose Operating System (OS) kernel are malicious. The modular design of ADS makes it application- transparent (i.e., no need to modify the application source code in order to deploy it) and almost hypervisor-independent (i.e., it can be implemented with any Type I hypervisor). To demonstrate the feasibility of ADS, we report the implementation and analysis of an Xen-based ADS system.
A new approach to digital image signatures (watermarks) is proposed in this study. An image signature algorithm consists of two stages : signature casting and signature detection. In the first stage, small changes are embedded in the image which afterwards are identified in the second stage. After chosing certain pixel blocks from the image, a constraint is embedded among their Discrete Cosine Transform (DCT) coefficients. Two different embedding rules are proposed. The first one employs a linear type constraint among the selected DCT coefficients and the second assigns circular detection regions, similar to the vector quantization techniques. The resistance of the digital signature to JPEG compression and to filtering are analyzed.
Based on the elliptic curve logarithm problem, a (t, n) threshold digital signature scheme was proposed in this paper. In the key generation phase, each participant¿s public and private keys, and the group public key are negotiated among all the participants with no trusted party required. In the signature generation phase, no secure communication is needed between any two participants. This scheme provides the capability of detecting cheating and identifying the cheat that may be from the internal participants or the external attackers. At the same time, this scheme has the advantages of elliptic curve cryptography. The security of this scheme is based on the difficulty of solving the elliptic curve discrete logarithm problem. Analyses show that this scheme is a computationally secure and efficient scheme.
We consider the problem of broadcasting sensitive information to many low cost receivers when the authenticity and integrity of the received messages are the determining factors but secrecy is not important. Although several methods exist to authentify information, as a rule, they lack the asymmetry the transmission system itself exhibits. Therefore, we propose a highly non- symmetric algorithm to generate and verify digital signatures. The algorithm is based on the computation of square roots. Since valid messages have a definite structure, we address the question of choosing the factors to get around the difficulty caused by the quadratic nonresidues.<<ETX>>
To realize various applications for content distribution via networks, the unique content identifier (Content ID) is indispensable. It can be used for negotiating secondary content use, automatic royalty sharing, content search and exchange, and illegal use detection. In August 1999, responding to a call from Prof. Dr. Hiroshi Yasuda at Univ of Tokyo, the Content ID Forum (cIDf) was established in Japan and began to construct a framework for contents distribution promotion while protecting copyrights. This document overviews the cIDf specifications and its activities.
Many image authentication methods have been proposed, in recent years, to protect image authenticity and integrity, but most have ignored the dangers of counterfeit attack. In this paper, we propose a new image authentication method, using a vector projection technique, for safety and security in digital systems based on a PKI cryptographic framework. In this method, the vector projective square (VPS) pair of each block can be calculated by a vector projection technique, and we prove that an attacker cannot forge a counterfeit image with the same VPS pair as the original image. In addition to addressing counterfeit attacks, we also propose a new remedial algorithm which applying non-uniform B-spline to repair the modified image. This paper, therefore, has five goals: (1) to verify image authentication, (2) to verify the integrity of an image received, (3) to locate any parts that were illegally modified or counterfeited, (4) to provide security against counterfeit attacks and (5) to repair the illegally modified parts.
The irruption of cryptography in the world of telecommunications has meant an explosion of new services. One of the main developments that contributed to this expansion has been the technology of digital identity. The maturity of this technology and its advanced state of implementation has permitted to draw new ways of communication within the society. However, the application of these solutions in particular environments is not an easy task. In order to face these demands, it is fundamental to previously analyze the scope of application, and to carry through a study of the technical, human and organizational requirements that this kind of services needs. This project presents the experience of implementing a digital identity solution in a university environment, namely the Universitat de les Illes Balears.
In addition to robustness and fragility, security is quite an important issue in media authentication systems. This paper first examines the insecurity of several block-based authentication methods under counterfeit attacks. Then, we prove that the proposed digital signature, which is composed of structural information, is content-dependent and provides security against forgery attacks. Experimental results demonstrate the benefits of exploiting structural information in a media authentication system.
IPSec (IP security) and SSL (secure socket layer) have been the most robust and most potential tools available for securing communications over the Internet. Both IPSec and SSL have advantages and shortcomings. Yet no paper has been found comparing the two protocols in terms of characteristic and functionality. Our objective is to present an analysis of security and performance properties for IPSec and SSL.
