Summary: This study proposes a secure two-party euclidean distance computation (SEDC) scheme based on Paillier encryption under a covert adversarial model. The scheme computes the secure two-party Euclidean distance using technologies such as Paillier encryption, and verifies the computation results to ensure data authenticity and no cheating during parameter interaction. The scheme is shown to be correct, confidential, and unforgeable under chosen-plaintext attack. Scheme comparison and efficiency analysis demonstrate that the scheme achieves a balance in the security model and is highly applicable due to its low communication and time complexity.

Summary: The proposed privacy-preserving indoor localization scheme uses received signal strength measurements from WiFi access points and secure two-party computation with cryptographic primitives to protect privacy. Optimizations reduce computation and communication overheads, and a proof-of-concept implementation on Android smartphones demonstrates practical feasibility for certain indoor localization applications.

Summary: This paper presents a secure privacy-preserving offloading scheme based on modified secret sharing for multi-party computation in IoT. The scheme is capable of fair computation offloading, privacy protection, result verification, and low overhead. Incentive and trust models are also developed to encourage honesty, willingness, and discourage delay among workers.

Summary: The paper discusses the importance of oblivious transfer in cryptography and proposes a generic construction based on asymmetric homomorphic encryption for building simple and efficient oblivious transfer protocols. The construction is instantiated with well-known homomorphic encryption schemes such as RSA, Paillier, and NTRU, and its security is further proven in the universal composable framework.

Summary: This research suggests a searchable encryption and deep hashing-based secure image retrieval technique that extracts more expressive image features and constructs a secure, searchable encryption scheme. Experimental results demonstrate the system's robust security and precise retrieval, improving retrieval accuracy by at least 37% compared to traditional hashing schemes and saving retrieval time by at least 9.7% compared to the latest deep hashing schemes.

Summary: This paper proposes an efficient privacy-preserving authentication scheme (PEPA) based on the Paillier cryptosystem to address the security and privacy issues in VANETs. The proposed scheme supports batch verification and allows users to interact without revealing sensitive information. Multiple authorities are used to reveal the identities of malicious users. System analysis and simulation show that PEPA achieves strong privacy-preserving authentication.

Summary: In this paper, a novel secure two-party quantum scalar product (S2QSP) protocol based on Fourier entangled states is proposed to achieve higher efficiency. The definition of unconditional security under malicious models is given, and an honesty verification method called Entanglement Bondage is proposed, which is used in conjunction with the modular summation gate to resist malicious attacks. The property of Fourier entangled states is used to calculate the scalar product with polynomial complexity. The unconditional security of our protocol is proved, which guarantees the privacy of all parties. Additionally, a privacy-preserving quantum matrix multiplication protocol based on S2QSP protocol is designed.
