s9: the first communication interface 2 receives the instruction of the first scheme, and the diagnostic device 1 executes the content of the first scheme according to the instruction so as to complete the calling of the internal system of the diagnostic device 1.
In the above embodiment, the diagnostic device 1 may implement multiple functions, where the multiple functions include, but are not limited to, screen capturing, ROOT acquisition, system time setting, network address black and white list adding, floating window control, memory card data formatting, user certificate installing, USB device uninstalling, Email account configuration, and system language modification, each function supports at least one protocol, and the protocol may be used for transmitting instructions of the functions through the first channel interface 2 and the second channel interface 4, a first function of the present application is exemplified as a screen capturing function, and according to a user's requirement, multiple schemes are designed for the screen capturing function in an internal system of the diagnostic device 1, including a screen capturing shape and a screen capturing form, and for the screen capturing shape, a square screen capturing, a rectangular screen capturing, a circular screen capturing, or any shape screen capturing can be selected; the forms of the screen capture include screen capture by double clicking the diagnostic device by using a finger joint, screen capture by shaking the diagnostic device, pulling down the system menu interface to select a conventional screen capture, and screen capture by aligning any gesture with the screen and keeping the one-second stop.
According to the screen capture function and the multiple screen capture scheme that display screen 5 shows, after the user selected the screen capture scheme, for example, first scheme is circular screen capture scheme, can trigger the instruction of circular screen capture scheme, management and control APP 3 passes through the instruction of the circular screen capture scheme of second communication interface 4 transmission extremely first communication interface 2, the instruction of circular screen capture scheme is received to first communication interface 2, diagnostic equipment 1 discernment instruction after discerning circular screen capture scheme, implements the content of circular screen capture scheme through the procedure, can obtain circular screen capture picture, sends the screen capture picture to display screen 5 and shows through the display screen. This application is interacted with diagnostic equipment 1 through management and control APP 3, calls the function of diagnostic equipment 1 internal system to satisfy user's demand, extend the expansion to the function that diagnostic equipment 1 has, improve user's experience and feel.
Since the governing APP 3 and the diagnostic apparatus 1 are two different processes, and the user wants to invoke the function inside the diagnostic apparatus 1, the authority of the internal system of the diagnostic apparatus 1 must be changed, but it is unsafe to modify the authority of the internal system, so a communication link needs to be established between the governing APP 3 and the diagnostic apparatus 1 to obtain a scheme corresponding to each function.
As shown in fig. 2, the APP management and control method of the present application further includes:
s10: setting a certificate on the diagnostic device 1;
s11: sending the certificate to a second communication interface 4 of the management and control APP 3 through the first communication interface 2;
s12: the second communication interface 4 of the management and control APP 3 receives the certificate;
s13: and the management and control APP 3 fuses the certificates.
Further, the diagnostic apparatus 1 uses RSA algorithm to make the certificate, which includes the following steps:
the diagnostic device 1 generates a security certificate by using a key slot tool, wherein the key slot tool is a keytool;
and/or the diagnostic device 1 generates a security certificate by using an Open source software tool, wherein the Open source software is Open SSL.
In the above embodiments, a certificate is a digitally signed statement that binds the value of a public key to the identity of the person, device or service holding the corresponding private key.
keytool is a key and certificate management tool. Keytool can generate public and private keys and help users manage their own public/private key pairs and associated certificates for self-authentication (by digital signature) (a user authenticates himself to another user/service) or data integrity and authentication services. Allowing users to store the public keys (in the form of certificates) of their communication peers.
keytools may create and manage key entries of a key repository, each key entry containing a private key and an associated certificate chain. The first certificate in the certificate chain contains a public key corresponding to the private key. When the key is first generated, the certificate chain contains only one element, namely the self-signed certificate.
Self-signed certificate: the issuer is the same as the principal, wherein the issuer is the signer and the principal is the entity to which the public key authenticated by the certificate belongs. When the call-key command is invoked to generate a new public/private key pair, the public key is also packaged into the self-signed certificate. When the certificate signing request is sent to a Certificate Authority (CA) after a certificate signing request is generated into a certificate request file by a CSR file, the CA generates a certificate, the certificate is imported into a keytool, and a certificate chain of the certificate generated by the CA replaces a self-signed certificate. At the bottom of the certificate chain is the certificate issued by the CA that certifies the subject public key. The next certificate in the certificate chain is the certificate used to authenticate the CA public key.
In many cases, this is a self-signed certificate, i.e. a certificate from the CA that certifies its own public key and is the last certificate in the certificate chain. In other cases, the CA may return a chain of certificates. The certificate at the bottom of the returned certificate chain is the same, i.e., a certificate signed by the CA, and the public key of the key item can be authenticated. But the second certificate in the certificate chain is signed by a different CA and is generated by other means, for example, a certificate request file generated by sending to a CSR file, a certificate authenticated by the public key of the CA. The next certificate in the certificate chain will be the certificate that authenticates the public key of the second CA, and so on until the self-signed "root" certificate is reached. Thus, each certificate in the certificate chain (from the first onward) authenticates the public key of the signer of the preceding certificate in the certificate chain, ensuring the security of the certificates.
In addition, the Open SSL used in the application is an Open secure socket layer protocol and is also a secure socket layer password library, which contains a password algorithm, a common secret key and certificate packaging management function and an SSL protocol and provides rich application programs for testing or other purposes. Of the components of Open SSL, the most important is the application of Open SSL, because the application of Open SSL provides relatively comprehensive functions, and the application of Open SSL mainly includes key generation, certificate management, format conversion, data encryption and signature, SSL testing, and other auxiliary configuration functions. Open SSL used in the application can generate a key, and the encryption algorithm, communication key negotiation and server authentication work are completed before application layer protocol communication through an SSL protocol. After that, the data transmitted by the application layer protocol is encrypted, so that the communication privacy can be ensured.
After generating the security certificate, the method verifies the security certificate, and the verification method comprises the following steps:
storing a file format of the security certificate using a CER file;
verifying the security certificate using a digital signature mapping public key with a public certificate in the CER file;
and if the security certificate is correct, fusing the security certificate and the management and control APP.
In the above embodiment, the secret keys are divided into a symmetric secret key and an asymmetric secret key, and the asymmetric secret key encryption technology uses a pair of matched secret keys for encryption and decryption, and has two secret keys, one is a public key and the other is a private key.
Files encrypted with a public key can only be decrypted with the private key, while files encrypted with the private key can only be decrypted with the public key. The public key is made public by its owner, while the private key must be kept secret. To send a secure message, the sender must encrypt the data using the recipient's public key, and once encrypted, only the recipient can decrypt it using its private key. Conversely, the user can also process the data with his own private key. In other words, the operation of the key pair is optionally directional. This provides the basis for a "digital signature" that a user can process data using his private key, if the user is to process the data using his own public key. Since only the owner himself knows the private key, the processed message forms an electronic signature: a document that cannot be generated by an unauthorized person, a digital certificate, which contains public key information to confirm the identity of the user who owns the key pair.
Digital signature (also called public key digital signature, electronic signature) is a common physical signature similar to that written on paper, but is implemented by using the technology in the field of public key encryption, and is used as a method for identifying digital information. A set of digital signatures typically defines two complementary operations, one for signing and the other for verification.
In the above embodiment, the process of verifying the security certificate is as follows: if the generated first certificate is the first certificate, the diagnostic equipment 1 generates a first abstract by using a segment of text information or a string of numbers by using a HASH function, and encrypts the first abstract by using a private key to generate a digital signature;
attaching the digital signature to a first certificate and sending the digital signature to the management APP;
the management and control APP 3 receives the first certificate attached with the digital signature and stores a file format of a public key certificate by using a CER file;
the management and control APP 3 decrypts the digital signature by using the public key to obtain a second abstract, wherein the content of the second abstract is a segment of text information or a string of numbers;
and decrypting the second digest through the HASH function to obtain a second certificate, if the first digest is consistent with the second digest and the first certificate is consistent with the second certificate, proving that the second certificate received by the management and control APP 3 is sent by the diagnostic device 1, and after the proving is successful, the first certificate and the second certificate are collectively called as a security certificate.
In addition, the managing APP 3 fusing the certificate includes the following steps:
storing the security certificate in a file directory of the management and control APP 3;
compiling the security certificate in the management and control APP 3 to generate a second APK, wherein the APK is in an application file format of an android system and is also called as an installation package;
if the management and control APP 3 does not have the first APK, directly saving a second APK in a file directory of the management and control APP 3, and completing fusion of the management and control APP 3 and the security certificate;
if management and control APP 3 includes first APK, then use second APK to replace first APK, accomplish management and control APP 3 with the integration of security certificate.
In the above embodiment, in order to ensure the security of the internal system of the diagnostic device 1, the keytool and the Open SSL tool are used to generate a secure certificate in the present application, the secure certificate is fused into the management and control APP 3, the certificate in the management and control APP 3 is compiled, and a second APK is generated, wherein the APK is stored in the file directory of the management and control APP 3, so that it can be ensured that the authority of the internal system of the diagnostic device 1 is not modified when the management and control APP 3 calls the scheme of the internal system of the diagnostic device 1, and under the security guarantee, the internal systems of the management and control APP 3 and the diagnostic device 1 can be used for data interaction, a plurality of functions of the internal system of the diagnostic device 1 are called, and a plurality of schemes corresponding to the functions are obtained.
Finally, when the first communication interface 2 and the second communication interface 4 transmit information, the management and control APP 3 and the diagnostic device 1 realize data interaction through Binder communication.
In the above embodiment, the Binder is an Android cross-process communication mode, and is a bridge for connecting the Service Manager to various managers (e.g., Window Manager, Activity Manager, etc.). The Binder communication provides data exchange among processes and is also suitable for data exchange among the same process. The process of the management and control APP 3 and the process of the diagnostic equipment 1 are different, and data interaction can be realized through Binder communication, so that data transmission between the two is rapid and efficient.
