A method is disclosed for managing access in a telecommunications network by utilizing a resource classification layer. The method involves receiving a request at a resource classification layer from a sender to obtain an access token for a receiver service. The sender is associated with a user role that has specific permissions and access rights corresponding to a data sensitivity threshold. The request includes a data payload. A classification value for the data payload is assigned using one or more resource classification models, which are trained on a log of past data payloads. A data sensitivity score is generated by comparing the classification value to a scale of classification values. The method then indicates whether the access token can be granted to the sender by comparing the data sensitivity score against the data sensitivity threshold to verify authorization.

A class of network packets can be labeled by inserting a token into a packet header field. Preferably the header field is available to intermediary devices in cleartext. A packet filter examines the packets, allowing packets with the token to pass while dropping others. For example, the token can indicate that the packet is part of a “trusted” class. The token can be calculated from a secret, shared between the sender and receiver, and a rotating value. In some embodiments, the token may be placed in all packets associated with a trusted sender or for some time before trust must be re-established. Alternatively, the token can be placed in an initial one or more packets of a particular flow, and the packet filter can look for such packet(s), deciding whether to allow or block them. The packet filter then treats subsequent packets in the same flow in the same way.

Procedures, methods, architectures, apparatuses, systems, devices, and computer program products for flexible transmissions in multipath sidelink relaying. A wireless transmit-receive unit, WTRU, may be configured with a bearer configured for multipath. Such a bearer may have a common, Uu, PDCP layer, but have two separate RLC entities associated with it—a Uu RLC entity for transmission / reception directly on Uu, and a SL RLC entity for transmission / reception via SL, to a WTRU to NW relay. Data on a multipath bearer can be transmitted via the Uu path, the SL path, or both, i.e., duplication. In the case the WTRU is configured for duplication, or decides to enable duplication for a multipath bearer (a duplication bearer), the WTRU may transmit PDCP PDUs both over the Uu path and the SL path.

This invention discloses a quantum-resistant method and system based on stateless signatures and execution isomorphism, belonging to the field of quantum-resistant cryptography. First, the sender generates an mKEM broadcast payload based on a modulus error rounding algorithm and signs it using a stateless hash signature algorithm. The receiver performs microsecond-level verification of the signature at the network card driver layer; if verification fails, the signature is silently discarded. After successful verification, a dedicated PQC hardware engine decapsulates the signature, implicitly outputting a pseudo-random scrap key if verification fails. The operating system executes an I / O-aware microarchitecture with isomorphic execution, forcing subsequent processes to maintain physical isomorphism in system calls, memory accesses, and peripheral bus activities, regardless of whether the key is real or scrap. This invention eliminates the risk of private key leakage caused by cloud-based state management through stateless signatures and completely eliminates distinguishable side-channel fingerprints across the entire link through physical-level execution isomorphism, achieving system-level quantum-resistant security in high-concurrency scenarios.
