Abstract: A method for re-provisioning a user equipment (UE, 140) after a first digital security certificate for the UE (140) has expired includes communicating content data to a controller (130) over a first secure communication channel after verification of a validity of a first digital security certificate. Once it is realized the first digital security certificate has expired, the UE (140) sends a certificate provisioning request message over an unsecure channel to the controller (130) as a request to the controller (130) to provision a second digital security certificate. The UE (140) signs the certificate provisioning request message with the private key for the now expired first digital security certificate. A second digital security certificate is signed by the rescue-secret private key at the controller (130) and sent to the UE (140), which verifies its authenticity with the corresponding rescue-secret public key.

Abstract: A non-transitory computer-readable storage medium, a secure application framework, a system, and a computer implemented method for enabling secure processing of data are disclosed. The method comprises steps performed within a secure application framework running in a trusted execution environment. The data encrypted using a first random key are received, the first random key is received in a secure way, and the encrypted data is decrypted using the first random key. The data are then input to the processing application, the processing application is executed to process the input data, and output data are received from the processing application. A second random key is generated, the output data are encrypted using the second random key, the second random key is encrypted using a public key of a storage device, and the encrypted output data and the encrypted second random key are sent to the storage device.

Abstract: A method (200) and an object analyzer (104) for analyzing objects in images captured by a monitoring camera (100) uses a first and a second sequence of image frames, wherein the first sequence of image frames covers a first image area (300) and has a first image resolution, and the second sequence of image frames covers a second image area (302) located within the first image area (300) and has a second image resolution higher than the first image resolution. A common set of object masks is provided wherein object masks of objects (304) that are identified as being present in both image areas are merged.

Abstract translation: 用于分析由监视摄像机（100）捕获的图像中的物体的方法（200）和物体分析器（104）使用第一和第二序列的图像帧，其中第一序列的图像帧覆盖第一图像区域（300 ）并且具有第一图像分辨率，并且所述第二图像帧序列覆盖位于所述第一图像区域（300）内的第二图像区域（302），并且具有高于所述第一图像分辨率的第二图像分辨率。 提供了一组共同​​的对象掩模，其中被识别为存在于两个图像区域中的对象（304）的对象掩模被合并。
