Embodiment Construction

[0061] In the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and / or B, which can mean: A exists alone, A and B exist simultaneously, and B exists alone, where A, B can be singular or plural. The character " / " generally indicates that the contextual objects are an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items, including any combination of single item(s) or plural item(s). For example, at least one item (unit) of a, b or c can represent: a, b, c, a and b, a and c, b and c, or a, b and c, wherein a, b, c Can be single or multiple.

Abstract

The invention discloses methods of data sending and equipment, and relates to the technical field of terminals. The method includes: receiving, by the terminal, an equipment certificate signed and issued by CA, generating a first key pair, sending a first certificate registration request to a first certificate server, and then receiving a first certificate sent by the first certificate server, wherein the first certificate is different from the device certificate; generating a second key pair by the terminal for a first application; using a first private key by the terminal to sign and issue an application certificate for the first application, and sending the application certificate to a first application server corresponding to the first application; and using a second private key by theterminal to sign data to be sent to the first application server, and sending the signed data to the first application server. The technical solution facilitates an effect of improving reliability, non-repudiation and security of data transmission, and facilitates, at the same time, an effect of avoiding leakage of sensitive information of manufacturing cycles, productivity and the like of terminal products of equipment merchants to application providers.
