Summary: The wide use of internet-connected services leads to the collection of massive personal data without our consent by service providers. This poses serious risks to individual privacy, particularly when data breaches have become common. To address this, regulations such as the EU's general data protection regulation have been introduced, focusing on giving control of personal data back to owners and the right to be forgotten. In this article, a cryptographic solution called forward-secure attribute-based puncturable encryption (FS-DABPE) is presented for achieving these requirements in outsourced storage. A concrete FS-DABPE construction is provided and its security is proven, along with a prototype implementation and extensive experimental results showcasing its feasibility and practicability.

Summary: We introduce a new concept of accountable attribute-based authentication with fine-grained access control (AccABA), which provides fine-grained access control, anonymity, and public accountability. We also propose a crowdsourcing scheme on blockchain that is attribute-based, fair, anonymous, and publicly traceable, aiming to filter qualified workers, ensure fair competition, and balance anonymity and accountability.

Summary: This article discusses the certificate-based aggregate signature (CBAS) scheme in the Industrial Internet of Things (IIoT) and proposes a specific construction method that improves the security and privacy of data. The article points out the vulnerabilities in previous schemes and presents forgery attacks against existing constructions. The proposed scheme enhances security through an improved construction based on the hardness of the discrete logarithm problem, proving its security in a random oracle model with efficiency in computation and communication.

Summary: This paper focuses on zero round-trip time (0-RTT) key exchange protocols and introduces a new cryptographic primitive called puncturable identity-based matchmaking key encapsulation mechanism (PIB-MKEM). Based on PIB-MKEM, a generic 0-RTT key exchange protocol with forward secrecy, mutual authentication, and replay resistance is proposed. The implementation of PIB-MKEM is also provided with extensive evaluations.

Summary: Accountable identity-based encryption (A-IBE) was proposed to address the key escrow problem in the IBE system. Retrievable A-IBE (RA-IBE) enhances the security by providing retrievability to the master secret key. However, current RA-IBE schemes lack the ability to support traceability and retrievability on well-formed private keys only.

Summary: Attribute-based authentication is important for fine-grained access control in cloud-based services, but it raises privacy concerns. Privacy Attribute-Based Credentials (Privacy-ABCs) support pseudonym-based authentication while hiding user identity. However, they require selective disclosure of attribute values. Our proposed pseudonym-based signature scheme combines the benefits of Privacy-ABCs, Attribute-Based Signatures (ABS), and mesh signatures to enable unlinkable pseudonym self-generation with embedded attributes and verifiable attribute delegation.

Summary: The leakage of private state information through various attacks poses a serious threat to computer systems, and there is a common requirement for cryptographic schemes to withstand these attacks. However, existing leakage-resilient public-key encryption schemes have high computational costs and fixed leakage upper bounds. To address these issues, a generic method for designing leakage-amplified PKE schemes with leakage resilience and CCA security is proposed, allowing flexible adjustment of leakage parameters. This method introduces a new cryptographic primitive and utilizes generic constructions to enhance security.
