Short message registration method and terminal

Abstract

The invention discloses a short message registration method and a terminal. The method comprises the steps that the location information of the terminal is acquired; a character string is generated, and the character string is encrypted by using the location information as an encryption key to generate an encrypted character string; an uplink short message is generated according to the encrypted character string, and the uplink short message is sent to a service terminal, wherein the uplink short message carries the identity information of the terminal; a downlink short message fed back by a server is received, wherein the downlink short message comprises the user registration information and a downlink encryption character string, and the user registration information is user information generated by the server which completes registration according to the identity information; the current location information of the terminal is acquired, and whether the downlink encryption character string is the same as the encrypted character string is judged according to the current position information; and if the downlink encryption character string is the same as the encrypted character string, the user registration information is saved. Since the location information of the user registration is random and unpredictable, security registration free of networkless connection can be completed by using the location information as the encryption key through uplink and downlink short messages.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a short message registration method and a terminal. Background technique [0002] At present, SMS registration is divided into uplink SMS registration and downlink SMS registration, but no matter which kind of SMS registration method needs the support of wireless network (such as WiFi or 4G network). For example, uplink SMS registration needs to obtain the content of the SMS to be sent from the server through the wireless network; downlink SMS registration needs to provide the mobile phone number to the server through the wireless network. However, in some remote places, underdeveloped areas, closed indoors and other places, there may be no wireless network, but at this time the ability to send and receive SMS is still reserved, and at this time the registration cannot be completed by using the existing uplink SMS registration or downlink SMS registration . There is a se...

Problems solved by technology

However, in some remote places, underdeveloped areas, closed indoors and other places, there may be no wireless network, but at this time the ability to send and receive SMS is still reserved, and at this time the registration cannot be completed by using the existing uplink SMS registration or downlink SMS registration

There is a security problem with SMS registration, because the content of plaintext SMS is easy to be stolen and tampered with
