    摘要： The disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates than 4G communication systems such as LTE systems. According to an embodiment, a method for operating a user equipment (UE) for a mutual authentication operation in an access stratum (AS) section comprises transmitting a first message including a first random value to a base station, receiving, from the base station, a second message including a second random value and a base station certificate for the base station, in response to the first message, and identifying information included in the base station certificate and verifying validity of the base station certificate, when the base station certificate is valid according to a result of the verification of the base station certificate.

    摘要： Technologies are disclosed for performing imaging operations via a direct secure wireless connection to an imaging device. An imaging device, such as a printer or scanner, obtains a signed certificate defining a security policy from an identity and access management (“IAM”) service. A computing device, such as a laptop or smartphone, obtains a signed certificate from the IAM service that defines access rights associated with the computing device. The imaging device and the computing device exchange the signed certificates. The imaging device approves or denies a request from the computing device to perform imaging operations by way of a direct secure wireless communication channel between the imaging device and the computing device based on the security policy and the access rights.

    摘要： A wireless communication, a station (STA) device, and an access point (AP) device are disclosed. The method includes: sending, by the STA device, a first frame by a randomized media access control MAC address that is encrypted or signed to the AP device. The first frame is configured to carry a first sequence number, the first sequence number is configured to obtain a MAC address identity recognition key of the STA device by the AP device, and the MAC address identity recognition key is configured to verify the randomized MAC address. Alternatively, the method includes: sending, by a STA device, a first message to an AP device. The first message includes a list of candidate MAC addresses encrypted by a public key of the AP device, and the list of candidate MAC addresses includes at least one randomized MAC address generated by the STA device.

    摘要： Methods, systems, and devices for wireless communications are described. In some examples, a wireless device may modify a cyclic redundancy check (CRC) generation and attachment operation based on a secret key to support enhanced security. In some examples, a first device may identify a set of data to transmit to a second device and prior to transmitting the set of data, the first device and the second device may obtain a set of key bits for data protection. The first device may generate a bit vector based on a subset of the set of key bits and a cyclic redundancy check polynomial. The transmitting device may then generate an encoded codeword based on the bit vector and transmit the encoded codeword to the second wireless device. The second device may decode the encoded codeword and obtain the set of data based on the set of key bits.

    摘要： This application provides a communication method and apparatus, to resolve a problem that security is low when a tag is triggered to perform random access in a communication network. The method includes: receiving first signaling, and determining, based on the first signaling, a second mask stored at a first storage location; and performing random access when a first mask matches the second mask. The first signaling indicates the first storage location and the first mask, the first signaling carries a first mask identifier, and the first mask identifier identifies the first storage location and/or the first mask. In embodiments of this application, a correspondence between a mask identifier and a storage location and/or a correspondence between the mask identifier and a mask are/is negotiated in advance, so that a part or all of masks and storage locations can be implicitly indicated by using a mask identifier.
