Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example one

Referring to fig. 1, a message sending method provided in an embodiment of the present invention is applied to a message forwarding party, and the message sending method includes:

step S10, receiving a to-be-converted message published by a first message participant, and extracting a message topic and a message body in the to-be-converted message, where the to-be-converted message is a message published by the first message participant in a publish-subscribe mode, and the to-be-converted message is subscribed only by the message forwarder;

in the basic publish-subscribe model, publishers publish messages to different topics (or channels) through message queue middleware, and subscribers will receive all messages on their subscribed topics. Topics are customized by the publisher and can be understood as categories of messages. How a subscriber subscribes to a topic specifically differs according to the specifically adopted message queue middleware, for example, in zeroMQ, the subscriber acquires a message in the topic of interest published by a publisher by listening to a sending port of the publisher. ZeroMQ is a message queue-based multi-threaded network library that abstracts underlying details of socket type, connection handling, frames, and even routing, providing sockets across multiple transport protocols. In addition, message queue middleware also has RabbitMQ, RocketMQ, ActiveMQ, Kafka, MetaMq, and the like. In this embodiment, the message queue middleware is not limited to be specifically used. The publish-subscribe mode is generally applied to a scenario where a message is broadcast to multiple parties in one direction, and generally does not need to receive a reply from a subscriber when a publisher sends a message in the publish-subscribe mode.

Therefore, based on the characteristics of the publish-subscribe model, in many application scenarios, the publish-subscribe model needs to be employed for message communication between communicating parties, for example, in a trusted context based privacy computing scenario. However, in the basic publish-subscribe mode, because the messages published by the publishers can be received by the subscribers as long as the subscribers subscribe to the corresponding topics, in the privacy calculation scenario, it is necessary to deal with a scenario in which one sender sends messages to some specified subscribers, and at this time, there is a risk of message leakage by using the basic publish-subscribe mode.

For the technical problem, in this embodiment, a plurality of parties needing to communicate in a privacy computation scenario are all referred to as message participants, a role, that is, a message forwarding party, is added outside the message participants, and messages that each message participant needs to send to other message participants are filtered and forwarded by the message forwarding party.

Specifically, any message participant needing to send a message to other message participants in a publish-subscribe mode is referred to as a first message participant, and a message participant specified by the first message participant to receive the message is referred to as a second message participant; there may be multiple second message participants, i.e., the first message participant specifies that a message be sent to multiple second message participants. It should be noted that "first" and "second" are used merely for convenience of reference and distinction, and are not intended to classify message participants. It will be appreciated that one message participant may be either sending a message to a second message participant as a first message participant or receiving a message sent by the first message participant as a second message participant.

After determining the message body which needs to be sent to the second message participant, the first message participant acquires the identifier of the second message participant. Wherein, each message participant is provided with a unique identifier in advance to distinguish each message participant. The first message participant may pre-store the identifiers of other message participants, and after the first message participant determines the second message participant, the identifier of the second message participant is obtained.

The first message participant encapsulates the identity of the second message participant in the message subject, which may specifically be encapsulated according to a pre-set specification. Further, in one embodiment, in order to facilitate the second message participant or the message forwarding party to trace back the sender of the message, the first message participant may also package its own identifier together with the identifier of the second message participant in the message subject according to a preset specification. The specific package specifications are many and not limited in this embodiment. Illustratively, one message topic is: party _2& party _3@ party _1, representing that the sender is party _1, the receiver is party _2 and party _3, and party _1, party _2 and party _3 are participant identifications of three message participants.

The first message participant packages the acquired message body and the message theme into a message (hereinafter referred to as a to-be-forwarded message for distinguishing), and publishes the to-be-forwarded message to the message forwarder in a publish-subscribe mode. In order to avoid that other message participants can obtain the message to be forwarded, the message published by the first message participant in the publish-subscribe mode can be set to be subscribed by the message forwarder only. It should be noted that there are many ways to implement that the message published by the first message participant in the publish-subscribe mode is only subscribed by the message forwarder, which are different according to the specifically adopted message queue middleware, and the implementation is not limited in this embodiment. Illustratively, a message can be published through a first message participant through a fixed sending port, while the port number of the sending port is only preserved in advance in a message forwarder, and the message forwarder receives a pending message published in a publish-subscribe mode by the first message participant by monitoring the sending port.

And the message forwarding party receives the message to be forwarded published by the first message participant in a publish-subscribe mode, and extracts the message theme and the message body in the message to be forwarded. It should be noted that, the packaging manner and the extracting manner of the message subject and the message body can be defined in advance between each message participant and the message forwarding party.

Step S20, analyzing the message theme to obtain the identifier of the second message participant;

after extracting the message theme in the message to be transferred, the message transfer party analyzes the message theme to obtain the identifier of the second message participant. Specifically, the encapsulation mode of the message topic may be predefined between each message participant and the message forwarding party, and the message forwarding party parses the message topic according to the parsing mode corresponding to the predefined encapsulation mode, so as to obtain the identifier of the second message participant carried in the message topic.

Step S30, searching for and acquiring a receiving address of the second message participant from a preset configuration file based on the identifier of the second message participant;

after the message forwarding party obtains the identifier of the second message participant, the receiving address of the second message participant is searched and obtained in the configuration file based on the identifier of the second message participant. The configuration file is a file preset in the message forwarding party, and includes an identifier and a receiving address of the second message participant, and the identifier and the receiving address of the second message participant are associated with each other, so that the message forwarding party can find the receiving address of the second message participant through the identifier of the second message participant. It should be noted that, the configuration file may be preset to include the identifications and receiving addresses of all message participants that need to be the message recipients. The receiving address may include an IP address of the message participant and a port number of the receiving port. It should be noted that the receiving address of the message participant is not changed once set, or the synchronization is changed in the configuration file when changed.

Further, if the message forwarder does not find the identifier of the second message participant in the configuration file or does not find the receiving address of the second message participant, the error information may be returned to the first message participant.

Step S40, publishing the message body to the second message participant in a publish-subscribe mode according to the receiving address.

After finding the receiving address of the second message participant, the message forwarder may issue the message body to the second message participant in a publish-subscribe mode according to the receiving address of the second message participant. The message forwarding party issues the message body to the second message participant according to the receiving address of the second message participant, so that the message participants except the second message participant cannot receive the message body, and the first message participant sends the message body to the second message participant in a targeted manner in a publish-subscribe mode and cannot be leaked to the message participants except the second message participant. It should be noted that the message forwarding party may specifically publish the message body to the second message forwarding party only by publishing the message body to the second message participant, or publish the whole message to be forwarded to the second message participant.

In the embodiment, by additionally arranging the message forwarding party, the message to be forwarded which is published by the first message participant in a publish-subscribe mode is received, and the message to be forwarded is set to be subscribed only by the message forwarding party, so that the message to be forwarded which is sent by the first message participant to the message forwarding party can only be received by the message forwarding party; extracting a message theme and a message body in the message to be forwarded through the message forwarding party, analyzing the message theme to obtain an identifier of a second message participant, searching a receiving address of the second message participant in a preset configuration file based on the identifier of the second message participant, and publishing the message body to the second message participant in a publishing subscription mode according to the receiving address, so that the message body sent to the second message participant by the message forwarding party can only be received by the second message participant; the whole process realizes that the first message participant pertinently sends the message body to the second message participant in the publish-subscribe mode and does not leak to the message participants except the second message participant, and solves the technical problem of message leakage risk existing in the basic publish-subscribe mode when needing to correspond to the situation that one sender sends the message body to some appointed subscribers in the privacy calculation scene.

Further, in an embodiment, before the step S20, the method further includes:

step a, detecting whether the message theme accords with a preset message theme standard or not;

after receiving the message to be forwarded and extracting the message theme from the message to be forwarded, the message forwarding party can firstly detect whether the message theme meets the message theme specification. The message topic specification is a specification of encapsulating a message topic that is set in advance according to needs, for example, specifies how to organize the identifier of the second message participant and the identifier of the first message participant as a message topic. For example, the message forwarder detecting whether the message topic conforms to the message topic specification may include detecting whether the message topic includes an identification of the second message participant, whether the identification of the second message participant included in the message topic is complete, and so on.

B, if the message theme is in accordance with the message theme specification, executing the step of analyzing the message theme to obtain the identifier of a second message participant;

if the message forwarding party detects that the message topic accords with the message topic specification, the message forwarding party analyzes the message topic to obtain the identifier of the second message participant, then searches the receiving address of the second message participant according to the identifier of the second message participant, and issues a message main body to the second message participant in a publish-subscribe mode according to the receiving address of the second message participant.

And c, if the message subject specification is not met, returning error information to the first message participant.

And if the message forwarding party detects that the message theme does not accord with the message theme specification, returning error report information to the first message participant. After receiving the error information, the first message participant may re-encapsulate the message topic and re-transmit the message to be forwarded.

In the embodiment, after the message to be forwarded is extracted from the message to be forwarded by the message forwarding party, compliance detection is performed on the message topic, the message is forwarded according to the identifier of the second message participant carried in the message topic when compliance is performed, and error information is returned when the compliance is not performed, so that the message of the first message participant can be accurately issued to the second message participant.

Further, in an embodiment, after the step S20, the method further includes:

step S50, searching the configuration file for the second public key of the second message participant corresponding to the identifier of the second message participant;

after obtaining the identifier of the second message participant, the message forwarder may further search, in the configuration file, a public key of the second message participant (hereinafter, referred to as a second public key for distinction) corresponding to the identifier of the second message participant. Each message participant can generate its own public key and private key in advance according to a specified key generation method, the public key of each message participant can be stored in a configuration file of the message forwarding party in association with the identifier of the participant, and the private key is only stored locally in the message participant. Illustratively, when the message participants and the message forwarder publish messages using ZeroMQ, the public key of the message participants may use the public key of the curve protocol, which is a ZeroMQ channel-encrypted protocol.

The step S40 includes:

step S401, encrypting the plaintext message body by using the second public key, and publishing the encrypted message body to the second message participant in a publish-subscribe mode according to the receiving address, so that the second message participant decrypts by using a second private key corresponding to the second public key to obtain the plaintext message body.

After the message forwarding party obtains the second public key, the message body in the plaintext may be encrypted by using the second public key, so as to obtain the encrypted message body. And the message forwarding party publishes the encrypted message body to the second message participant in a publish-subscribe mode according to the receiving address of the second message participant. And after receiving the encrypted message body, the second message participant decrypts the encrypted message body by using a second private key which is locally stored and corresponds to the second public key to obtain a plaintext message body, wherein the second private key is a private key which is owned by the second message participant and corresponds to the second public key.

In this embodiment, the public key of each message participant is stored in the preset configuration file in the message forwarding party, the second public key of the second message participant is found in the configuration file according to the identifier of the second message participant obtained by parsing from the message topic, and the message body is encrypted by using the second public key and then issued to the second message participant, thereby ensuring the security of the message body in the process of forwarding the message body to the second message participant by the message forwarding party.

Further, in an embodiment, the step S10 includes:

step S101, receiving a message to be converted issued by a first message participant, and extracting a message subject and an encrypted message main body in the message to be converted, wherein the encrypted message main body is obtained by encrypting a message main body of a plaintext by the first message participant by using a first private key of the first message participant;

step S102, searching a first public key corresponding to the first private key from the configuration file, and decrypting the encrypted message body by adopting the first public key to obtain the message body in a plaintext;

the first message participant can also encrypt the message body by using a private key of the first message participant (hereinafter referred to as a first private key) after acquiring the message topic and the message body, then package the message body and the message topic together to obtain a message to be forwarded, and issue the message to be forwarded of the message body containing the ciphertext to the message forwarding party. The message forwarding party extracts the message body of the ciphertext from the received message to be forwarded, searches a public key (hereinafter referred to as a first public key) of a first message participant from the configuration file, and decrypts the message body of the ciphertext by using the first public key to obtain the message body of the plaintext. The message body is encrypted by the first message participant and then distributed to the message forwarding party, so that the safety of the message body is ensured in the process of forwarding the message body to the message forwarding party by the first message participant.

The step S40 includes:

step S402, publishing the plaintext message body to the second message participant in a publish-subscribe mode according to the receiving address.

After the message forwarding party obtains the plaintext message body, the message forwarding party may publish the plaintext message body to the second message participant in a publish-subscribe mode according to the receiving address of the second message participant, or may encrypt the plaintext message body by using a second public key of the second message participant and publish the encrypted plaintext message body to the second message participant.

Further, in an embodiment, the message sending method further includes:

step S60, starting a monitoring thread to monitor the update state of the configuration file;

when a message participant is added or deleted, the manager can add the participant information such as the identifier, the receiving address, the public key and the like of the message participant in the configuration file. The message forwarding party can start a monitoring thread to monitor the update state of the configuration file so as to adopt the latest configuration file to perform message forwarding service.

The step S30 includes:

step S301, searching for a receiving address of the second message participant corresponding to the identifier of the second message participant in the latest configuration file monitored by the monitoring thread.

After the message forwarding party obtains the identifier of the second message participant, the message forwarding party can search the receiving address of the second message participant corresponding to the identifier of the second message participant in the latest configuration file monitored by the monitoring thread.

In the embodiment, the information of the participants of each message participant is maintained through the configuration file in the message forwarding party, the monitoring thread is started through the message forwarding party to monitor the updating state of the configuration file, and the message forwarding service is performed by adopting the latest configuration file, so that the message participants are added and deleted only by updating the configuration file, the message participants and the message forwarding party do not need to be restarted, and meanwhile, the network complexity and the maintenance cost when the communication parties perform message communication in a subscription publishing mode are greatly reduced.

Example two

On the basis of the first embodiment, the message sending method in the foregoing embodiment may further include step S70, and the step of receiving the pending message issued by the first message participant in step S10 further includes step S103, which is described below. In this embodiment, the same or similar contents as those in the first embodiment may refer to the above description, and are not repeated herein.

Step S70, starting a fixed local receiving port;

step S103, monitoring the local terminal receiving port to receive the message to be transferred issued by the local terminal receiving port from the first message participation direction.

In the basic publish-subscribe mode, a subscriber can subscribe the message published to the topic by the publisher in a mode of monitoring the transmitting port of the publisher, and the message published by the publisher can be received as long as the subscriber knows the transmitting port of the publisher, so that when the publisher only needs to publish the message to some specified subscribers, the message can be leaked to other subscribers.

To solve the technical problem, in this embodiment, the message forwarder may activate at least one fixed receiving port (hereinafter referred to as a local receiving port, where the local refers to the message forwarder). And presetting the port number of the local receiving port in each message participant in advance.

And the first message participant publishes the message to be forwarded to the local receiving port in a publish-subscribe mode according to the port number of the local receiving port. The message forwarding party acquires the message to be forwarded issued by the first message participant by monitoring the receiving port of the home terminal. Because the first message participant is to publish the message to be forwarded to the local receiving port of the message forwarding party, the message participants except the message forwarding party cannot receive the message to be forwarded, so that the first message participant can send the message body to the second message participant in a publishing subscription mode in a targeted manner, and the message body cannot be leaked to the message participants except the second message participant.

EXAMPLE III

On the basis of the first embodiment, the step of receiving the pending message issued by the first message participant in step S10 of the message sending method in the above embodiment may further include step S104, which is described below. In this embodiment, the same or similar contents as those in the first embodiment may refer to the above description, and are not repeated herein.

Step S104, receiving the message to be forwarded issued by the first message participant to the domain name of the forwarding party.

Because all messages pass through the message forwarding party after the message forwarding party is added, the message forwarding party puts the messages into the memory in a queue mode, and thus, when the number of message participants is increased and the number of messages to be sent is increased, the machine memory for deploying the message forwarding party becomes a short board.

To solve this problem, in this embodiment, a plurality of message forwarders may be provided, the configuration files in the respective message forwarders are the same, and the plurality of message forwarders implement the same message forwarding service. When there are a plurality of message forwarders, IP addresses of the plurality of message forwarders may collectively bind a domain name (hereinafter, referred to as a forwarder domain name).

The first message participant can publish the message to be forwarded to the domain name of the forwarding party in a publish-subscribe mode, and since the message to be forwarded is published to the domain name of the forwarding party, the message published by the first message participant in the publish-subscribe mode can be subscribed only by the message forwarding party. Because the domain name of the forwarding party is bound with a plurality of IP addresses, the domain name service defaults to poll each IP address bound by the domain name of the forwarding party, so that the message to be forwarded is issued to the message forwarding party corresponding to the polled IP address, the message to be forwarded issued by each first message participant is dispersed to each message forwarding party for processing, the effect of shunting is achieved, and the message sending method supports large-scale message sending.

step B10, starting a fixed home terminal receiving port, and starting the fixed home terminal receiving port, wherein the home terminal receiving port is provided with a fixed port number;

step B20, receiving the message body published to the local terminal receiving port by the message forwarding party in the publish-subscribe mode based on the port number;

The second message participant may activate at least one fixed receive port (hereinafter referred to as a home receive port, the home referring to the second message participant). And configuring the port number of the local receiving port as a receiving address of a second message participant in a configuration file of a message forwarding party in advance.

After the message forwarding party acquires the identifier of the second message participant, searching a receiving address of the second message participant corresponding to the identifier of the second message participant in the configuration file, wherein the receiving address comprises the port number of the local receiving port. And the message forwarding party publishes a message body to the local terminal receiving port in a publish-subscribe mode according to the receiving address of the second message participant. And the second message participant acquires the message main body issued by the message forwarding party by monitoring the receiving port of the home terminal. Because the message forwarding party issues the message body to the local receiving port of the second message participant in a targeted manner, the message participants except the second message participant cannot receive the message body, so that the first message participant sends the message body to the second message participant in a targeted manner in a publish-subscribe mode, and the message body is not leaked to the message participants except the second message participant.
