Abstract: A method for importing and exporting configurations includes: generating a public key and a private key of a manufacturer; generating a certificate of the manufacturer; storing the certificate of the manufacturer in each of products; and signing a public key by using the private key of the manufacturer to generate a signature of the manufacturer; wherein the products receive the certificate of the manufacturer, at least one configuration and a signature of a customer which is generated by signing the at least one configuration by using a private key of the customer, as well as each products verifies the signature of the manufacturer in accordance with the stored certificate of the manufacturer, verifies the signature of the customer in accordance with the certificate of the manufacturer, and applies the at least one configuration when authenticated. A system for importing and exporting configurations is also provided.

Abstract: A verification code generation method is performed in an electronic device which is for performing encoding to generate a video/audio stream having multiple data segments. The verification code generation method includes the following steps. Each time one of the data segments is generated by the encoding, a first-level checksum associated with the data segment is generated, and the first-level checksum is recorded in an accompanying verification file. At an interval of every N data segments of the data segments, a second-level checksum is generated for W consecutive first-level checksums, and the second-level checksum is recorded in the accompanying verification file, such that a subsequent verification method can quickly verify integrity of a part of data according to the accompanying verification file. Wherein, W is a positive integer greater than or equal to 2, N is a positive integer greater than 0 and smaller or equal to W.
