ESAM Multi-function of the most secure embedded module

What is ESAM?
ESAM (Embedded Secure Access Module) is the Embedded security control Module.ESAM hardware has a sensor (voltage, clock, temperature, light, filter (prevent rush/burr), independent of the internal clock (CLK), (SFI) detection mechanism, passive and active shield, glue logic (difficult to reverse engineer circuit), handshaking circuits, high density multi-layer technology, with a metal shield protection layer, to detect internal data self-destruct after external attack, encryption, virtual address bus and the memory chip tamper-proof design, unique serial number and hardware error detection, random number generator, the silicon power analysis and so on security structure,With anti-detection, anti-attack, self-destruct and other hardware security features.ESAM chip operating system has the characteristics of secure file key storage, perfect security mechanism, standard encryption algorithm and so on.
The application of ESAM security module is related to a variety of special or general intelligent devices. For all the products and application systems requiring high data security requirements such as identity authentication, data encryption/decryption, safe storage, communication confidentiality and so on, ESAM embedded security control module can play its unique role in security control.It has two - way identity authentication, data encryption and decryption, decentralized key export, internal decentralized key, digital signature, electronic wallet, transmission line protection, data security storage and other functions.

Applications of the ESAM security module include:
1) Smart card meter: smart card electricity meter, water meter, gas meter, heat meter, etc.;
2) Communication equipment: encrypted Modem, encrypted fax machine, encrypted multiplexer;
3) Financial equipment: encryption password keyboard, financial POS machine, payment password, bank password box;
4) Tax-controlled equipment: tax-controlled taxi meter, tax-controlled refueling machine, tax-controlled cash register;
5) Traffic toll: parking meter, bus toll terminal, vehicle-mounted road and bridge toll terminal equipment;
6) Conditional reception: TV set-top box (STB), PC receiving card, add and de-disturb front end/terminal equipment;
7) Network security: LAN management, login, folder encryption, software protection;
8) Other equipment: smart card water dispensers, smart card charging air conditioners, Internet TV and other equipment.
Key feather

Implementation method
(FYI)
1, key installation
● Application software needs to install: authentication key SK (or decentralized key)
The application software should have DES and an algorithm for generating random numbers
● Installation in ESAM: authentication key SK '(or disperse key) or an important parameter for program execution
2. Software certification process
● Apply software to generate random numbers
● Send random number to ESAM for encryption and return the result X '=DES(SK',RND)
● The software calculates the authentication code X=DES(SK,RND) with its own decentralized key
● Software comparison
