The field of machine learning is moving towards a direction of increased security and efficiency, with a focus on addressing the challenges of data privacy and scalability. Researchers are exploring new techniques such as secure multi-party computation, federated learning, and meta-reinforcement learning to improve the security and efficiency of machine learning models. Notable papers in this area include one that proposes a novel framework for private inference using a helper-assisted malicious security dishonest majority model, which achieves state-of-the-art performance in terms of efficiency and accuracy. Another paper introduces a self-supervised learning enhanced hijacking attack framework for vertical federated learning, highlighting the potential vulnerabilities of this approach. Additionally, a paper on split learning and function secret sharing demonstrates the effectiveness of this approach in reducing communication and computational costs while maintaining high security guarantees.
