Login method, registration method and login device as well as login and refrigeration system

Abstract

The invention discloses a login method, a registration method and a login device as well as a login and refrigeration system. The login method comprises the following steps: receiving a login request sent by a client, wherein the login request carries user identification information and private key information provided by a user; encrypting a verification quest into a ciphertext by use of a public key corresponding to the user identification information in the login request and returning the ciphertext to the client to allow the client to decrypt the ciphertext by use of a pre-stored private key, and obtaining the verification question and an answer to be verified of the user to the verification question; receiving the answer to be verified sent by the client and determining whether the answer to be verified is correct; if the answer to be verified is correct, logging in by use of the user identification information. According to the login method, a plurality of authentication manners such as the public key, the private key, the private key password and the verification question are combined to achieve higher safety.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a login method, a registration method, a login device, and a login and registration system. Background technique [0002] Network account registration and login is a basic and important task on the Internet.

Problems solved by technology

[0004] The above methods have their own advantages and disadvantages. For example, the use of passwords or passphrases is cheap and easy to operate, but it is easy to be intercepted or cracked by a third party; the method of using keys and tokens, such as USB certificates, can improve security. robustness, but has high distribution and maintenance costs and can also be lost
