This application provides a cloud service access method, device, and storage medium. In this embodiment, a terminal can display a cloud service access icon on the communication interface of the cloud service's instant messaging service group. In response to triggering the access icon, the terminal generates an access request to access the cloud service and accesses the cloud service based on the access request. This enables access to the cloud service through instant messaging software without needing to log in with the user's cloud service account and password, achieving login-free access to the cloud service. This enriches the cloud service access methods and helps improve the flexibility of cloud service access.

The present invention relates to a common entrance access control system for multi-family housing. By generating a dynamic pass-through key that combines unit number information and the speaker's unique voice fingerprint information, which are simultaneously extracted from the spoken voice through a single action in which a user verbally utters the unit number of their residence, and by ensuring that the entrance door opens only when it matches the voice fingerprint of the resident registered for the spoken unit number, the invention realizes completely contactless and media-free access without keypad input, card tagging, or smartphone operation. The present invention adopts a spatial-speaker combined authority verification mechanism in which the spoken unit number itself functions as a claim of residence authority and the voice fingerprint of the same utterance verifies the authenticity of that claim. This provides a reverse-binding effect that denies access to voices not registered for the speaking unit, even if those voices are registered for another unit. In addition, it comprehensively provides various technical measures specialized for the common entrance environment of multi-family housing, such as voice fingerprint registration for multiple residents per household, branching of access policies by resident type, automatic intercom call switching when a legitimate resident does not match, normalization of Korean apartment pronunciation variations, bidirectional correction of adjacent apartment misidentification based on voice fingerprint matching, processing of common entrance environment noise, speaker separation for multiple speakers, and defense against recording playback attacks through liveness detection.

This invention provides a fast disk persistence system and its control method based on AMP architecture. The system includes: a power monitoring unit; a master control domain and slave domains; a heterogeneous storage buffer; and a hardware arbitration locking unit. The hardware arbitration locking unit is signal-connected to the heterogeneous storage buffer and also to the master control domain, with its other end connected to the storage medium. The master control domain can control the access permissions of each domain to the storage medium through the hardware arbitration locking unit according to the corresponding instructions sent by the power monitoring unit. The hardware arbitration locking unit solves the problem of mutual exclusion of resources among multiple domains, and the master control domain arbitration mechanism achieves exclusive, contention-free access control of the storage medium, eliminating the problem of concurrent conflicts among multiple domains and solving the problem of storage device preemption when multiple operating systems are simultaneously persisted to disk under the AMP architecture.

The application discloses a wireless communication parameter generation method, system and device based on a dynamic security root, and belongs to the technical field of wireless communication. The core of the method is that: the two communication parties share a security key (K_sec) in advance, and independently obtain or evolve a consistent time-varying parameter (S) based on a predetermined mechanism; the two parties independently generate the same communication parameter (Param) through the same cryptographic function based on K_sec and S, and realize zero signaling collaboration. The predetermined mechanism is preferably a protocol security state machine based on a dynamic security root (DSF), and the DSF is composed of K_sec, an initial anchor point and a state transition rule (Rule_ID). Rule_ID defines three configurable rules: rule A uses broadcast timing, rule B is based on a hash chain, and rule C is based on a logical epoch, which are respectively suitable for short-time high robustness, continuous high performance and continuous high energy efficiency scenes. Based on this unified paradigm, the application further realizes security pilot bearing, scheduling-free access, zero signaling switching, high-precision positioning and synchronization recovery and the like, systematically solves the problems of large signaling overhead, poor synchronization robustness, disconnection between security and process in the traditional scheme, and provides a complete solution of endogenous security and full-stack zero signaling for the next generation of wireless communication systems.
