Maxim Integrated's DeepCover® solution uses two-way challenge-response SHA-256 authentication and encryption algorithms to protect embedded designs, peripherals, or sensors.
China, Beijing, September 24, 2013. Maxim Integrated Products, Inc. (NASDAQ: MXIM) introduced the DeepCover security certification device (DS28C22) to better provide IP protection. The DS28C22 highly secure encryption scheme is used for host controllers to authenticate peripherals or embedded designs. Providing encrypted communication is another advantage of the device.
The DeepCover embedded security solution effectively protects sensitive data through multiple layers of advanced physical mechanisms, and provides the most secure storage of authentication keys for the system. DS28C22 adopts SHA-256 authentication algorithm based on FIPS 180, integrates strong, password-protected two-way, challenge-response security authentication function, and small information encryption mechanism. Through two-way authentication, the host and peripherals verify each other to protect the peripheral IP from being modified by unauthorized hosts. DS28C22 can provide a high degree of security protection for a variety of applications, including: peripherals / consumables, sensors, network equipment, IP authorization, and programmable logic controller (PLC) and other industrial applications.
Main advantage
· Reliably and securely protect IP from the threat of counterfeit products and away from hacker attacks: the two-way security authentication model allows two-way authentication and encryption between the host system and the DS28C22 embedded slave, enhances chip-level protection, and implements authentication keys Safe storage.
· Simple and fully programmable: The internal 3Kb user memory has four user-programmable protection modes; the SHA-256 option enables the user to control the characteristics of the terminal product by setting security.
· Factory pre-programming effectively improves security: Maxim also provides DS28C22 pre-programming services to prevent supply chain manufacturers from modifying the program to ensure that keys are not exposed.
· Fast and safe encryption process: DS28C22 has a built-in dedicated hardware acceleration engine for SHA calculation.
Industry evaluation
· Scott Jones, executive director of Maxim Integrated, said: "We have more than 20 years of R & D experience to resist intrusion attacks. By using multiple layers of security mechanisms and SHA-256 algorithms, we can provide designers with peace of mind data security protection."
· Colin Barnden, principal analyst at Semicast Research, said: "Equipment manufacturers must protect their equipment and only open access to authorized users. Today's symmetric encryption algorithms are generally used for system protection to ensure that the security of symmetric encryption keys is specific The most critical part of the implementation process. "
Supply information
· Available in 8-lead TDFN package
· Operating temperature range from -40 ° C to + 85 ° C
The Friction Disc is a kind of Printer Accessories.
The cartridge is irradiated by laser beam to adsorb toner, and then the toner is hot pressed by fixing roller for printing. In this process, there will be part of toner residual, which can not be "granules returned to the warehouse"; Automatic cleaning function is not adsorbed new toner particles and directly print, will remain toner away, fully ensure the next printing effect. And the Plate-Grid plays an important role. When high voltage generator to a high voltage electrode, wire electrode with reseau formed between a strong electric field, and release the corona, wire electrode and the photosensitive drum ionizes the air between the air ions migrate to the drum surface, make the photoconductor (drum) surface is full of charge, so can spare toner "adsorption to warehouse", so as to save toner, The purpose of reducing environmental pollution.
