With the continuous development of electronic communication technology, the status of communication security is also gradually rising. More and more enterprises and individuals are paying attention to whether the information related to themselves is secure, whether normal communication activities can ensure the "non disclosure of business data and personal privacy", and avoid being used by "intentional people"; Can daily communication activities ensure that relevant information can be transmitted to the corresponding recipient in a timely manner to avoid information loss. At this point, communication security has become an indispensable part of the entire communication service.
As is well known, communication consists of three basic elements: equipment, network, and information. Therefore, communication security refers to the safety production, safety construction, and safety management issues of equipment, network, and information. The so-called communication devices refer to the relevant devices used to send and receive communication information content, namely communication modules and communication cards (SIM cards). The communication module determines the access and transmission method of information and is the processor of communication information, while the SIM card is the authentication device of the communication channel. Only when the communication module uses SIM cards that can be authenticated by the communication operator can the communication device 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 built-in the normal network access certificate licensed by the communication operator, and to constantly control the normal operation status of the communication equipment during the communication transmission process. In order to meet this condition, a very small storage space will be left in the SIM card to run the network access certificate, meeting the communication security and operator screening needs of customers.
The communication network refers to the public network used for communication. Currently, the communication market in China is firmly occupied by three communication operators, namely China Mobile, China Unicom, and China Telecom. The infrastructure used to maintain communication network security is built, maintained, and operated by China Iron Tower Co., Ltd. jointly funded by the three major communication operators. Under the protection of the state-owned system, users often focus on the issue of which communication operator's public network to use, as well as concerns about the impact of major natural disasters and network fluctuations on basic communication facilities. Information security of communication networks is clearly important, but it is easy to overlook.
As the security protection system of the Internet becomes so fragile today, under the rampant dark network of hackers or criminals, invisible security vulnerabilities are repeatedly breached at the touch. Compared to mature Internet architecture, the fragile security of the Internet of Things, which is still in its infancy, appears even more immature. For example, at the beginning of last year, the smart toys of Spiral Toys, a foreign company, were hacked, resulting in the leakage of voice and account information for 2 million parents and children, posing serious social risks; It has also been revealed that 175000 IoT security cameras manufactured by a company in Shenzhen may be vulnerable to hacker attacks, and these security cameras can provide monitoring and multiple security solutions, including network cameras, sensors, and alarms. The severity of the consequences can be imagined. According to statistics, more than 71 million IoT devices with security risks have been exposed worldwide, including various types of devices such as routers, cameras, firewalls, printers, VPNs, etc. This is enough to demonstrate the increasingly prominent security needs of IoT devices.
The security vulnerabilities of general IoT products that integrate sensors and basic communication functions are even more worrying. On such a low-cost device, there are too many types of network environments, operator systems, and operators using a common system, which is enough to demonstrate the weakness of IoT network security. How to ensure the confidentiality, integrity, and availability of communication information in the context of IoT information dissemination and reception, To achieve the purpose of communication security.
In order to ensure the security of communication, the linkage protection between communication equipment and communication network has become a relatively effective type of communication security solution at present. The main approach of this type of communication security solution is to carry out corresponding security management arrangements on communication equipment and communication management pipelines, and manage and ensure the security of communication information online through the management platform.
Communication equipment monitoring network stability
On one side of the communication equipment, the stability of the communication network is mainly monitored through communication modules to ensure that communication information is not missing or changed during the transmission process of the communication network. The corresponding monitoring results are always returned to the communication management platform. Once a problem occurs, an alarm is immediately triggered and a corresponding fault reporting and troubleshooting process is formed to maintain information integrity and reliability.
Intelligent deployment of communication management platform
On one side of the communication management platform, intelligent allocation is used to automatically initiate, confirm, terminate, and check each communication process. The first thing to ensure is the confidentiality of information. Through the management platform and the use of technologies such as information encryption, authorization authentication, access control, and secure communication protocols, the communication information sent by each communication device should be processed accordingly to prevent the illegal leakage of communication information to unrelated personnel, so that useful information can only be obtained by authorized objects.
Secondly, it is necessary to ensure the effectiveness of information and ensure that authorized users' information acquisition is effective at all times under normal circumstances. For information acquisition under abnormal circumstances, communication information can be re collected, and there is a secondary acquisition mechanism in case of significant fluctuations in the network, so that the information collection process can reply to normal in a timely manner.
Furthermore, the management platform should intelligently control the timing of information transmission and 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 storage to avoid channel congestion during information transmission and improve information management efficiency. Finally, the communication management platform should appropriately store the obtained information and confirm that the source of the corresponding information is a reliable and authenticated source, verify that the information is valid, and screen for invalid information.
From this, it can be seen that in the linkage protection of information security, the communication management platform still plays the main role. Even in some security management schemes that include communication cards, SDKs are written into the communication cards, allowing the SIM card itself to provide sufficient feedback to the communication management platform. SIM cards not only play a role in communication authentication, but also add to the entire security management system, further strengthening the connection between the platform, devices, and SIM cards, allowing the communication management platform to better implement corresponding security measures.
Subsequently, with the continuous development of this technology, new technologies such as writing cards in the air and multiple numbers on one card emerged. Communication management platforms were able to adjust and convert SIM card communication operators based on the strength of communication signals through the SDK in the SIM card, automatically switching to better signal communication operators, and utilizing the platform's own effective information acquisition mechanism to achieve real-time communication and never dropping the line. This technology largely solves the signal strength problem caused by different communication operators due to base station deployment, and can play an extremely important role in the application of mobile devices and cross-border equipment trade.
By relying on this communication management model, communication equipment, communication network, and communication information can be combined together, greatly improving data security and reliability, reducing the risk of data loss and leakage, and safeguarding electronic communication. The Liuxin · eSIM series chips under Liuxin Technology integrate main functions such as communication network adaptation, device authentication, encryption firmware, and global communication IMSI configuration, greatly improving the online rate of devices, communication services, and device security protection.
