With the continuous development of electronic communication technology, the status of communication security is gradually rising, and more and more companies and individuals are beginning to pay attention to whether the information related to themselves is safe, and whether normal communication activities can ensure business data and personal privacy. "The law does not spread to the six ears", to avoid being used by "wishful people"; can daily communication activities ensure that relevant information can be transmitted to the corresponding information receiver in time to avoid information loss. At this time, communication security has become a link that cannot be ignored in the entire communication service.
As we all know, communication is composed of the three most basic elements of equipment, network, and information. Therefore, communication security refers to the safety production, safety construction and safety management of equipment, network, and information. The so-called communication equipment refers to the related equipment used to send and receive communication information content, that is, the communication module and the communication card (SIM card). The communication module determines the access and transmission mode of information, and is the processor of the communication information, while the SIM card is the authentication device for the communication channel. Only when the communication module uses a SIM card that can be authenticated by the communication operator, the communication device can use the public network specified by the communication operator for normal network communication activities.
The main function of the SIM card provided by the communication operator is to build in the normal network access certificate approved by the communication operator, and to control the normal operation status of the communication equipment at all times during the communication transmission process. In order to meet this condition, a very small storage space will be reserved in the SIM card to run the network access certificate to meet the customer's communication security and operator identification requirements.
Communication network refers to the public network used for communication. At present, my country's communication market is firmly occupied by the three communication operators of China Mobile, China Unicom, and China Telecom. The infrastructure used to maintain the security of the communication network is operated by the three major communication operators. The construction, maintenance and operation of China Tower Co., Ltd., jointly funded by the firms. Under the protection of the state-owned system, users often focus on the issue of which communication operator’s public network to use, and worry about network fluctuations caused by special natural disasters affecting basic communication facilities. The information security of communication networks is obviously very important. But it is most easily overlooked.
When the Internet's security protection system has become so vulnerable today, under the dark web where hackers or criminals are rampant, invisible security vulnerabilities are repeatedly broken. Compared with the mature Internet architecture, it is still at a disadvantage. In the budding stage of the Internet of Things, its fragile security appears to be more immature. For example, at the beginning of last year, a foreign Spiral Toys company's smart toys were attacked by hackers, resulting in the disclosure of the voice information and account information of 2 million parents and children, which caused serious social risks. It also broke a company in Shenzhen. The explosion of the 175,000 IoT security cameras manufactured may be attacked by hackers, and these security cameras can provide surveillance and multiple security solutions, including web cameras, sensors, and alarms. The seriousness of the consequences can be imagined. According to statistics, more than 71 million IoT devices with security risks have been exposed worldwide. These devices include routers, cameras, firewalls, printers, VPNs and other types of devices, which is enough to show that the security needs of IoT devices are becoming more prominent.
The general Internet of Things products that integrate sensors and basic communication functions are even more worrying. On such a low-cost device, too many types of network environments, operator systems, and operators use a common system, which is enough to see The weakness of the Internet of Things network security, in the case of Internet of Things information dissemination and reception, how to ensure the confidentiality, integrity and availability of communication information to achieve the purpose of communication security.
In order to ensure the security of communication, the linkage protection of communication equipment and communication network has become a more effective type of communication security solution. The main approach of this type of communication security plan is to carry out corresponding security management arrangements on communication equipment and communication management pipelines, and to manage and ensure the security of communication information online through the management platform.
Communication equipment monitors network stability
The communication equipment side mainly monitors the stability of the communication network through the communication module to ensure that the communication information is not missing or changed during the transmission of the communication network, and the corresponding monitoring results are always returned to the communication management platform. If there is a problem, it will be alerted immediately, and a corresponding troubleshooting process will be formed to maintain the integrity and reliability of the information.
Intelligent deployment of communication management platform
On the side of the communication management platform, through intelligent deployment, the initiation, confirmation, termination and inspection of each communication process are automatically completed. The first thing to ensure is the confidentiality of information. Through the management platform, and using information encryption, authorization authentication, access control, secure communication protocols and other technologies, the communication information sent by each communication device is processed accordingly to prevent communication information. It is illegally leaked to unrelated persons, so that useful information can only be obtained by authorized objects.
Secondly, it is necessary to satisfy the validity of the information and ensure that the information acquisition of authorized users under normal conditions is valid at all times. For information acquisition under abnormal conditions, it can reach the re-collection of communication information, and it can have secondary acquisition when the network is subject to major fluctuations. The mechanism to enable the information collection process to return to normal in a timely manner.
Furthermore, the management platform should intelligently control the timing of information transmission and information storage. In daily information collection, network congestion is a very common network problem. The communication management platform should reasonably allocate the corresponding time for information transmission and information storage to avoid Channel congestion occurs in the process of information transmission, which improves the efficiency of information management. Finally, the communication management platform should appropriately store the acquired information, and confirm that the source of the corresponding information is a reliable source that has been authenticated, verify that the information is all valid information, and screen out invalid information.
It can be seen that the communication management platform plays a major role in the linkage protection of information security. Even in some security management solutions that include communication cards, SDK is written into the communication card, so that the SIM card itself can feed back enough information to the communication management platform. The SIM card not only plays a role in communication authentication, but also It has also joined the entire security management system to further strengthen the connection between the platform, equipment, and SIM card. The communication management platform can better carry out corresponding security measures.
Later, with the continuous development of this technology, new technologies such as writing cards in the air and multiple numbers with one card appeared. The communication management platform can communicate with the SIM card through the SDK in the SIM card according to the strength of the communication signal. Operators make corresponding adjustments and conversions, automatically switch to communication operators with better signals, and use the platform's own effective information supplementation mechanism to achieve real-time communication and never drop the line. This technology, to a large extent, solves the problem of signal strength caused by the deployment of base stations by different communication operators, and can play an extremely important role in the use of mobile equipment and cross-border equipment trade.
Relying on this communication management model, the three elements of communication equipment, communication network, and communication information can be combined together, which greatly improves data security and data reliability, reduces the risk of data loss and data leakage, and protects electronic communications. The core eSIM series of chips under the GIZ Technology Group integrates the main functions of communication network adaptation, device authentication, encrypted firmware, global communication IMSI configuration, etc., which greatly improves the online rate of equipment, and the security of communication services and equipment. .
