        abstract = {This study presents a hierarchical key assignment scheme (HKAS) built on the closest vector problem in an inner product space (CVP-IPS). The proposed scheme delivers a scalable, flexible, cost-effective, and high-performance solution. Key features include a CVP-IPS-based construction, the use of two public keys, a unique basis set assigned to each class, a direct access mechanism for enhanced user convenience, and a thorough mathematical and algorithmic framework detailing all processes. Unlike traditional top-down approaches, this scheme avoids hierarchical dependencies, ensuring uniform basis set lengths and consistent key derivation costs across all classes. This design significantly reduces the overhead typically incurred by higher classes in conventional structures. With its ability to support both vertical and horizontal scalability through the use of access graphs, the scheme is proven to achieve strong key indistinguishability security (S-KI-security). This research marks a substantial advancement in HKAS systems, offering improved efficiency, robust security, and practical benefits for diverse applications.},
