Embodiment Construction

[0043] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0044] see figure 1 and figure 2 As shown, the security method for the mobile terminal to access the cloud storage server in the embodiment of the present invention comprises the following steps:

[0045] S1: When the MP (smart phone terminal) needs to access the CS (cloud storage server), the MP sends access request packet information to the CS. The request packet information includes MPID (identity information of MP) and N 1 (the first random number selected by the MP), go to step S2.

[0046] S2: CS returns the access response packet information to MP, and the access response packet information includes N 1 , N 2 (random number selected by CS), CHelp (ciphertext auxiliary information) of K (session key) selected by CS for communication with MP. CS uses K to derive IK (integrity verification key), and CS uses IK to MIC 1 (First Integ...

Abstract

The invention discloses a safety method for accessing a mobile phone terminal to visit a cloud storage server, and relates to the field of mobile phone information safety. The safety method comprises the following steps: 1) when MP needs to access CS, sending access request for grouping to SC by the MP; 2) sending access to the MP by the CS to respond to the grouping; 3) guiding out an encryption key and an integrity checking key by MP, verifying grouping effectiveness and sending operation request for grouping to the CS; 4) checking the grouping effectiveness by receiving a calculating and checking code through CS, and constructing operation responding to grouping and sending the operation to MP; 5) judging the correctness of a random number and calculating and checking the grouping effectiveness by the MP, wherein the data access operation is successfully after the random number is judged to be correct. In an authentication process, the authentication of the cloud server is not needed, so that the security authentication and key negotiation needs between the mobile phone terminal and the cloud server can be met, not only can the communication expense be saved, but also the calculating performances can be remarkably improved on the condition of guaranteeing the safety.

Description

technical field [0001] The invention relates to the field of mobile terminal information security, in particular to a security method for a mobile terminal to access a cloud storage server. Background technique [0002] With the development of wireless network technology and embedded technology, mobile smart phone terminals have become an indispensable part of people's daily life; with the development of network convergence technology and the increase of network bandwidth, mobile smart phone terminals have gradually grown into people's consumption digital The main tool for content, storage, and processing of daily data. Therefore, the digital content industry based on mobile smart phone terminals has a wide development space and application prospects. [0003] For user data stored on smartphone terminals, the following two problems are usually faced: [0004] (1) Limitations of storage capacity and processing power [0005] Although the smart phone terminal provides stora...
