Abstract

A chameleon-hash function is a hash function that involves a trapdoor the knowledge of which allows one to find arbitrary collisions in the domain of the function. In this paper, we introduce the notion of chameleon-hash functions with ephemeral trapdoors. Such hash functions feature additional, i.e., ephemeral, trapdoors which are chosen by the party computing a hash value. The holder of the main trapdoor is then unable to find a second pre-image of a hash value unless also provided with the ephemeral trapdoor used to compute the hash value. We present a formal security model for this new primitive as well as provably secure instantiations. The first instantiation is a generic black-box construction from any secure chameleon-hash function. We further provide three direct constructions based on standard assumptions. Our new primitive has some appealing use-cases, including a solution to the long-standing open problem of invisible sanitizable signatures, which we also present.

Abstract

Sanitizable signatures allow for controlled modification of signed data. The essential security requirements are accountability, privacy and unlinkability. Unlinkability is a strong notion of privacy. Namely, it makes it hard to link two sanitized messages that were derived from the same message-signature pair. In this work, we strengthen the standard unlinkability definition by Brzuska et al. at PKC ’10, making it robust against malicious or buggy signers. While state-of-the art schemes deploy costly group signatures to achieve unlinkability, our construction uses standard digital signatures, which makes them compatible with existing infrastructure.

27. Redactable Signature Schemes for Trees with Signer-Controlled Non-Leaf-Redactions

Abstract

Redactable signature schemes (\(\mathsf{RSS }\)) permit to remove parts from signed documents, while the signature remains valid. Some \(\mathsf{RSS }\)s for trees allow to redact non-leaves. Then, new edges have to be added to the tree to preserve it’s structure. This alters the position of the nodes’ children and may alter the semantic meaning encoded into the tree’s structure. We propose an extended security model, where the signer explicitly controls among which nodes new edges can be added. We present a provably secure construction based on accumulators with the enhanced notions of indistinguishability and strong one-wayness.

Abstract

Malleable signatures allow the signer to control alterations to a signed document. The signer limits alterations to certain parties and to certain parts defined during signature generation. Admissible alterations do not invalidate the signature and do not involve the signer. These properties make them a versatile tool for several application domains, like e-business and health care. We implemented one secure redactable and three secure sanitizable signature schemes on secure, but computationally bounded, smart card. This allows for a secure and practically usable key management and meets legal standards of EU legislation. To gain speed we securely divided the computing tasks between the powerful host and the card; and we devise a new accumulator to yield a useable redactable scheme. The performance analysis of the four schemes shows only a small performance hit by the use of an off-the-shelf card.

29. Contingency Revisited: Secure Construction and Legal Implications of Verifiably Weak Integrity

Abstract

Digital signatures are by far the most prominent mechanisms to detect violations of integrity. When signing rights are delegated, the integrity protection is gradually weaker as the delegatee’s actions are not considered integrity violations. Taken to an extreme, delegating the right to undetectably change everything to everyone will achieve a property called contingency. Contingency was introduced as the “dual of integrity” in 2009 by Rost and Pfitzmann in German [26] and later translated into English in 2011 [4]. Contingency describes the exact opposite of integrity: the provable absence of integrity. Following this line of privacy research, this paper gives the first rigorous definition of contingency and presents a cryptographic protocol build upon a transparent sanitizable signature scheme. Hence, contingency is a verifiable statement that the signer explicitly desired that the integrity status of data is not verifiable. We analyze legal implications and applications of contingent information.

Abstract

Sanitizable signatures enable a designated party to modify signed documents in a controlled way, while the derived signature still verifies. In this paper, we introduce the notion of non-interactive and public accountability. It allows a third party to determine whether a message-signature pair was issued by the signer or the sanitizer. The original notion of accountability does not satisfy European legal standards, while non-interactive public accountability does. A contradictory security goal is the indistinguishability of message-signature pairs from the signer and the sanitizer, a.k.a. transparency. As state-of-the-art schemes often satisfy transparency, they can only achieve a weaker notion of accountability. We show that non-interactive public accountability does not contradict privacy by proving that an existing scheme by Brzuska et al. BIOSIG '09 satisfies both notions. We then extend the scheme to also satisfy blockwise public accountability. Overall, for e-business applications within the EU, opting for non-interactive public accountability can be preferable over transparency.

Abstract

In this paper, we present a provably secure redactable signature scheme allowing to independently redact structure and content. We identify the problems when structure is not separated from content, resulting in an attack on the scheme proposed at VLDB '08 by Kundu and Bertino. The attack allows for changing the semantic meaning of a given tree. We introduce a rigid security model, including consecutive redaction control, to formalize the required behaviour of our scheme. Moreover, we present first performance evaluations of our implementation to demonstrate the practical use of the presented scheme.

Abstract

In this paper, we present new attacks on the redactable signature scheme introduced by Kundu and Bertino at VLDB '08. This extends the work done by Brzuska et al. at ACNS '10 and Samelin et al. at ISPEC '12. The attacks address unforgeability, transparency and privacy. Based on the ideas of Kundu and Bertino, we introduce a new provably secure construction. The corresponding security model is more flexible than the one introduced by Brzuska et al. Moreover, we have implemented the schemes introduced by Brzuska et al. and Kundu and Bertino. The practical evaluation shows that schemes with a quadratic complexity become unuseable very fast.

Abstract

We analyse the legal requirements that digital signature schemes have to fulfil to achieve the Statutory Trust granted by the EU electronic signature laws ("legally equivalent to hand-written signatures"). Legally, we found that the possibility to detect subsequent changes is important for the Statutory Trust. However, detectability was neither adequately nor precisely enough defined in the technical and legal definitions of the term "Data Integrity". The existing definition on integrity lack a precise notion of which changes should not invalidate a corresponding digital signature and also lack notions to distinguish levels of detection. We give a new definition for Data Integrity including two notions: Authorized changes, these are changes which do not compromise the data's integrity; and their level of detection. Especially, the technical term "Transparency" introduced as a security property for sanitizable signature schemes has an opposite meaning in the legal context. Technically, cryptography can allow authorized changes and keep them unrecognisably hidden. Legally, keeping them invisible removes the Statutory Trust. This work shows how to gain the Statutory Trust for a chameleon hash based sanitizable signature scheme.

Abstract

We present the performance measures of our Java Cryptography Architecture (JCA) implementation that integrates sanitizable signature schemes into the XML Signature Specification. Our implementation shows mostly negligible performance impacts when using the Ateniese scheme with four different chameleon hashes and the Miyazaki scheme in XML Signatures. Thus, sanitizable signatures can be added to the XML Security Toolbox. Applying the new tools we show how to combine different hash algorithms over different document parts adding and removing certain properties of the sanitizable signature scheme; this mixing comes very natural in XML Signatures. Finally, we motivate that existing definitions for the property of Transparency are counterintuitive in these combinations. Our conclusion is that the document-level Transparency property is independent of the sub-document properties Weak and Strong Transparency.

Abstract

We have identified the following three problems for the processing of aggregated personal information with respect to privacy preferences: Unverifiable proof of consent, unverifiable proof of consent for aggregated personal data, and no verification if the consent is still established. We constructed a solution based on a hash tree structure and digitally signed only the hash tree's root value. Thus, a verifiable signature can be retained even if data items are omitted and a valid signature serves as signal of consent. To re-assure that no change of consent has taken place we propose the use of certificate revocation mechanisms. As a side-effect these mechanisms allow to maintain a record of personal data usage and thus creates a win-win situation for both parties involved.

Abstract

Smartcards are being used as secure endpoints in computer transactions. Recently, the connectivity of smartcards has increased and future smartcards will be able to communicate over the TCP/IP protocol. In this work, we explore options for using a smartcard as an active node in a communication network rather than as an endpoint. We envision in particular a proxy firewall running on a smartcard and combining the best of both worlds: the smartcard as a secure environment, and the proxy firewall for securing the network. Facilitating the various security options smartcards offer, we show how to design a secure network firewall on a smartcard. We illustrate the usefulness of such a device in several scenarios.
