Abstract
The invention discloses an early warming emergency linkage mechanism implementation frame based on a CAP (Common Alerting protocol), which provides supports of system communication, data exchange and information aggregation based on distributed multi-channel early warning information issuing. On the base of CAP1.0 (Common Alerting protocol 01), the frame defines a data exchange format, a data communication encryption and decryption mode and a data collection and aggregation mode, provides conversion support for multiple early warning information content formats by adopting a converged communication gateway technology and realizes automatic conversion of information formats required by multiple issuing channels; due to adoption of a message queue technology, all information can be safely and reliably transmitted, and information issuing and monitoring measures can be provided. The usability, the monitorability and the manageability of all parts of an emergency linkage platform can be ensured trough a tcp/ip long connection mode; the communication security is guaranteed through a digital certificate encryption and decryption mode. The frame provides early warning support guarantee for weather, earthquake, public health and various other emergent events.
Description
Technical field
The present invention relates to areas of information technology, particularly a kind of emergency cooperative of early warning based on CAMEL Application Part mechanism implementation framework.
Background technology
Reply and dispose various types of Emergent Public Events be a trans-sectoral business, trans-regional, involve a wide range of knowledge, the system engineering of comprehensive strong, multi-level multidisciplinary intersection.The collection of Emergent Public Events early warning information and issue, be the key link in the contingency management operating mechanism, directly has influence on governments at all levels, all departments emergency disposal to Emergent Public Events.Accident occurs, and, if lack emergency mechanism, there is no unobstructed information channel, the measure of public order not being safeguarded, will cause that The rumors flew, produces psychosocial fear, civil order is chaotic, and even some unprincipled fellows also can seize the opportunity the enforcement illegal activity.As the early stage that SARS spreads, the shortage due to relevant information and the transmission of prevention knowledge, cause rumor to rise from all around, cause public psychology to put upon the full stretch, so that it is panic to produce local psychology, and minority opportunist utilizes the masses' Psychological phobia to seek private interests, and upsets the public, makes extreme event.
Guangdong Province not yet builds the unified Emergent Public Events early warning information distribution platform of the whole province at present, although the issue of Guangdong Province's burst early warning information has obtained certain achievement, various public pre-warning information issuing systems in the whole province various places, have tentatively been set up for various Emergent Public Events, comprise Mobile Phone Short Message Service, landline telephone service, rural area typhon subsystem, the means such as electronic display subsystem and Public meteorology television channel, but the various means of services also do not form the unified mechanism of coordinating each other, lack interlock, can not reallocate resources well, the problem of solution information seamless coverage, must affect to quality and the efficiency of whole society's issue public contingent even early warning information.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of emergency cooperative of early warning based on CAMEL Application Part mechanism implementation framework, realizes following target:
(1) construction object of early warning information release management platform subsystem comprises unified receive, process natural calamity, accident, public health event, the large class Emergent Public Events information of social security events four, in time issue early warning information, make relevant department and the public in time obtain early warning information, take corresponding measure, thereby ensure life property safety of people to greatest extent.
(2) early warning information release management platform is used for supporting various issue means subsystems by multiple means of communication and communication media; adopt TV, radio broadcasting, the Internet, SMS, electronic display synchronously to broadcast mode; propagate fast, in time, exactly to various circles of society and broad masses of the people, for Emergent Public Events emergency disposal, society prevent and reduce natural disasters, protect people's life and property safety, provide science and technology support and decision-making foundation.
(3) set up the distribution platform of unified Emergent Public Events early warning information, different early warning information is adopted different issue template, prediction scheme; Various early warning information published methods and channel are managed, can issue collection typing, the information of information and carry out stock management.
(4) provide unified information gateway function, flexible adaptive much information publication channel, realize the much information format conversion, docking much information publication channel system, the function of the unified input interface of realization, multiple output interface.
(5) the Emergent Public Events emergency advance warning situation of coming into force is carried out objective and accurate assessment, guarantee that the early warning information issue can obtain ideal effect.Utilize space displaying, the analysis ability of GIS platform, select the distribution effect of the different channels of Overlapping display by the figure layer, facilitate the manager to check intuitively coverage and efficiency that information is issued.
For achieving the above object, the invention provides a kind of communication system based on public CAMEL Application Part, comprise the CAMEL Application Part definition, communication modes and encryption and decryption mode;
Described CAMEL Application Part is used for: border relation and relevant interface standard between clear and definite provincial early warning information release management platform and publication channel platform, realize the unified issue of early warning information and to the effective monitoring of publication channel platform;
Described encryption and decryption mode is used for: ensure each side in the situation that trust and safe communicating.
Digital certificate mechanism is a kind of security mechanism that is widely adopted at present, and the PKI System Framework that standard will be adopted in provincial early warning information publishing center ca authentication center, adopt X.509 certificate format.
PKI provides a technological frame (having comprised agreement, service, standard etc.),, by adopting X.509 certificate and public-key technology, can provide comprehensive, enough safety to support to application (particularly E-Bus iness application): the user authenticates, data confidentiality, data integrity, non-repudiation, key management etc.Therefore advise both sides' system when communicating, should adopt the digital certificate cipher mode based on the PKI system.
When both sides' system adopted the digital certificate cipher mode to communicate, provincial management platform should be the publication channel platform following content is provided:
Publication channel platform private key;
Provincial management platform PKI;
The API module that comprises digital signature, encryption and decryption functions.
When using authenticated encryption mode based on digital certificate to communicate, concrete flow process is as follows.
1) source is signed to initial data: source is by own private key certificate, generation＜signature〉nodal information, and add＜signature in node at＜message nodal information.
2) source is encrypted initial data and signature together: the public key certificate that source provides by destination end, to whole＜message〉node is encrypted.(to the encryption of inclusion information)
3) source sends to destination end with enciphered message: source sends to destination end with packet (inclusion after packet header+encryption).
4) destination end data decryption: destination end is decrypted the packet that receives by the private key certificate of oneself.
5) legitimacy of destination end certifying signature: the public key certificate that destination end provides by source, right＜signature〉the nodal information legitimate verification of signing.
