The Internet of Things is good, but its overall connectivity also provides opportunities for unintentional or malicious data corruption and contamination, but these vulnerabilities can be solved using encryption methods.
At present, we are linking everything and the Internet of Things (IoT) is born. Once this overall connection is completed, the overall results it brings will enable us to embark on a series of exciting new systems. However, this has produced a large amount of data that must be trusted and processed.
With the Internet of Things, access to information is almost at your fingertips.
However, as people have said: "Buyers should be careful." The Internet of Things is good, but its overall connectivity also provides opportunities for unintentional or malicious data corruption and contamination, but these vulnerabilities can be solved using encryption methods. One of the choices faced by the system designer is whether to choose a software-based or hardware-based security solution. Both technologies protect against data being read or modified without authorization; however, it is necessary for us to further examine its different features before final selection.
Software-based security
The software security system makes use of existing system resources and takes the lead in the market. These solutions are relatively inexpensive because they share resources with other programs in the system to protect and protect the data. Another function implemented by software is the ability to modify and upgrade security as threats and vulnerabilities evolve.
Software security systems increase the workload of the host processor and may therefore affect the efficiency of the entire system. In addition to these concerns, the software approach is a weak link in the system's security architecture. Secrets are still easy to find, and algorithms often run on general-purpose, non-secure hardware, with the same risk of being attacked.
In summary, software-based security is cost-effective, and it can effectively prevent unauthorized system access in a physical security environment.
Hardware-based security
Hardware-based security uses application-specific integrated circuits (ICs) or processors with dedicated security hardware—they are designed to provide cryptographic capabilities and defense against attacks. Security operations such as encryption and decryption and identity authentication occur at the level of the IC hardware optimized for the performance of cryptographic algorithms. In addition, sensitive information such as key and terminal application key parameters are protected within the electrical boundaries of the cryptographic hardware.
The security IC includes circuit blocks such as a math accelerator, a random number generator, a non-volatile memory, a tamper detection, and a physical non-imitation function (PUF). The PUF module is particularly interesting - it has unique features that allow sensitive data, such as keys, to be protected from intrusion or reverse engineering. The Maxim DS28E38 is an example of a PUF-integrated security IC that can both generate keys and prevent intrusive security attacks.
Tampering with the chip is both difficult and expensive, so cybercriminals can't attack hardware-based security. In addition, when attacked, the security IC can shut down operations and destroy sensitive data before it is compromised. This solution may be slightly more expensive, but it can greatly reduce the risk of unauthorized access to embedded devices, peripherals, and systems.
Hardware-based security is very effective for all application environments, especially those environments where terminal devices are exposed and physically accessible to the bad guys.
Fasten your seat belts
In short, security is a complex subject. However, in order to prevent unfavorable conditions on end products such as Internet of Things devices, we must directly face and solve this problem. Software-based security is a choice, but hardware security solutions are the path to complete, reliable security.
