   "abstract": "Age verification is increasingly mandated by law, especially in online services. In this paper, we present a proof-of-concept protocol for privacy-preserving age verification. Our approach allows users to prove compliance with age requirements without revealing their identity to the service provider. Furthermore, the website remains unaware of which authority issued the age certification, and the certification authority does not learn which website is making the request or the specific age being verified. This design ensures strong privacy guarantees for all parties involved. Its properties served as a baseline for part of the reference document published by the French regulator ARCOM.",

He recently acknowledged a bug in its security analysis for the adaptive case. We analyze the proof of the original paper and propose a simple patch of the scheme. More interestingly, we then modify it and present a more efficient commitment scheme secure in the UC framework, with the same level of security as Lindell's protocol: adaptive corruptions, with erasures. The security is proven in the standard model (with a Common Reference String) under the classical Decisional Diffie-Hellman assumption. Our proposal is the most efficient UC-secure commitment proposed to date (in terms of computational workload and communication complexity)."

   "abstract": "Traceable signatures schemes were introduced by Kiayias, Tsiounis and Yung in order to solve traceability issues in group signature schemes. They wanted to enable authorities to delegate some of their detection capabilities to tracing sub-authorities. Instead of opening every single signatures and then threatening privacy, tracing sub-authorities are able to know if a signature was emitted by specific users only. In 2008, Libert and Yung proposed the first traceable signature schemes proven secure in the standard model. We design another scheme in the standard model, with two instantiations based either on the SXDH or the DLin assumptions. Our construction is far more efficient, both in term of group elements for the signature, and pairing computation for the verification. Besides the \"step-in\" (confirmation) feature that allows a user to prove he was indeed the signer, our construction provides the \"step-out\" (disavowal) procedure that allows a user to prove he was not the signer. Since list signature schemes are closely related to this primitive, we consider them, and answer an open problem: list signature schemes are possible without random oracles."

   "abstract": "Partially-blind signatures find many applications in the area of anonymity, such as in e-cash or e-voting systems. They extend classical blind signatures, with a signed message composed of two parts: a public one (common to the user and the signer) and a private one (chosen by the user, and blindly signed). The signer cannot link later the message-signature to the initial interaction with the user, among other signatures on messages with the same public part. This paper presents a one-round partially-blind signature which achieves perfect blindness in the standard model using a Common Reference String, under classical assumptions: CDH and DLin assumptions in symmetric groups, and similar ones in asymmetric groups. This scheme is more efficient than the previous ones: reduced round complexity and communication complexity, but still weaker complexity assumptions. A great advantage is also to end up with a standard Waters signature, which is quite short. In addition, in all the previous schemes, the public part required a prior agreement between the parties on the public part of the message before running the blind signature protocol. Our protocol does not require such pre-processing: the public part can be chosen by the signer only. Our scheme even allows multiple messages provided from independent sources to be blindly signed. These messages can either be concatenated or aggregated by the signer, without learning any information about them, before returning the blind signature to the recipient. For the aggregation (addition of the messages), we provide a new result, of independent interest, about the Waters hash function over non binary-alphabets."

Their proof systems have found numerous applications, including group signature schemes, anonymous voting, and anonymous credentials. In this paper, we demonstrate that the notion of smooth projective hash functions can be useful to design round-optimal privacy-preserving interactive protocols. We show that this approach is suitable for designing schemes that rely on standard security assumptions in the standard model with a common-reference string and are more efficient than those obtained using the Groth-Sahai methodology. As an illustration of our design principle, we construct an efficient oblivious signature-based envelope scheme and a blind signature scheme, both round-optimal."

   "abstract": "Electronic cash (e-cash) refers to money exchanged electron- ically. The main features of traditional cash are usually considered also desirable in the context of e-cash. This is for example the case for on- line transferability, meaning the recipient of cash in a transaction can transfer received money in a later payment transaction to a third per- son without contacting a central authority. Among security properties, the anonymity of the payer in such transactions has been widely stud- ied. This paper proposes the first efficient and secure transferable e-cash scheme with the strongest achievable anonymity properties, as introduced at ACNS 2008. In particular, it should not be possible for adversaries who receive a coin to decide whether they have owned that coin before. Our proposal is based on two recent cryptographic primitives: the proof system by Groth and Sahai, whose randomizability enables the strongest notions of anonymity, and the commuting signatures by Fuchsbauer."

   "abstract": "Randomizable encryption allows anyone to transform a ciphertext into a fresh ciphertext of the same message. Analogously, a randomizable signature can be transformed into a new signature on the same message. We combine randomizable encryption and signatures to a new primitive as follows: given a signature on a ciphertext, anyone, knowing neither the signing key nor the encrypted message, can randomize the ciphertext and adapt the signature to the fresh encryption, thus maintaining public verifiability. Moreover, given the decryption key and a signature on a ciphertext, one can compute (\"extract\") a signature on the encrypted message. As adapting a signature to a randomized encryption contradicts the standard notion of unforgeability, we introduce a weaker notion stating that no adversary can, after querying signatures on ciphertexts of its choice, output a signature on an encryption of a new message. This is reasonable, since due to extractability a signature on an encrypted message can be interpreted as an encrypted signature on the message. Using Groth-Sahai proofs and Waters signatures, we give several instantiations of our primitive proven secure under classical assumptions in the standard model: the decision-linear assumption in symmetric bilinear groups. As an application, we show how to construct a non-interactive receipt-free universally verifiable e-voting scheme. Besides, our primitive also yields an efficient round-optimal blind signature scheme based on standard assumptions."

   "abstract": "In 2008, Groth and Sahai proposed a general methodology for constructing non-interactive zeroknowledge (and witness-indistinguishable) proofs in bilinear groups. While avoiding expensive NP-reductions, these proof systems are still inefficient due to a number of pairing computations required for verification. We apply recent techniques of batch verification to the Groth-Sahai proof systems and manage to improve significantly the complexity of proof veri.cation. We give explicit batch verification formulas for generic Groth-Sahai equations (whose cost is less than a tenth of the original) and also for specific popular protocols relying on their methodology (namely Groth's group signatures and Belenkiy-Chase-Kohlweiss-Lysyanskaya's P-signatures)."
