DS243 chip decryption

Chip decryption center, high-end chip decryption laboratory, providing DS2432 / DS2431 chip decryption service, welcome to inquire.
The following are the main features of the DS2432 chip:
DS2432 integrates 1024-bit EEPROM, 64-bit key, an 8-byte register/control page (which contains five user read/write sections), a 512-bit SHA-1 engine, and a full-featured 1-Wire interface in a single chip. Each DS2432 has its own factory-engraved 64-bit ROM registration code that ensures unique identification and absolute traceability. Data is transmitted in serial according to 1-Wire protocol, with only one data line and return ground wire. DS2432 has an auxiliary storage area called a register that acts as a buffer when writing data to the main memory or register or when installing a new key. The data is first stored in the scratchpad and can be read back from here. After verification, assuming DS2432 receives a matching 160-bit MAC, the Copy Scratchpad command data abbreviation DS2432 will transfer the data to the final storage unit. The computation of MAC involves the key and additional data stored in DS2432 (including device identity register). No MAC is needed when new keys are loaded. When reading a storage page or calculating a new key, the SHA-1 engine can also be activated to calculate a 160-bit MAC without loading it. Typical applications of DS2432 include intellectual property security testing, after-sales management of consumer goods and data loader certification.

MAXIM DS28E01 IC unlock combines 1024-bit EEPROM with a challenge-response security certification that complies with the ISO/IEC110118-3 secure hashing algorithm (SHA-1). In a single chip, 1024-bit EEPROM (divided into four pages, 256 bits per page), 64-bit key, one register page, 512-bit SHA-1 engine and 64-bit ROM sequence code are integrated. DS28E01 transmits data serially in accordance with 1-Wire protocol at a communication rate of 15.3 kbps (standard rate mode) or 125 kbps (high speed mode), requiring only one data line and one return ground wire, thus saving the occupancy of the controller I/O port to the maximum extent.

In the past few decades, DS28E01 decryption has evolved from prototype development tools to flexible solutions for consumer and industrial applications. As the complexity of DS28E01 decryption logic rises from thousands of gates to millions of gates, the DS28E01 decryption device can accommodate more critical system functions.
Today, DS28E01 is chosen to decrypt, and various technologies are used to protect the configuration data – OTP (anti-fuse, flash-based reprogrammable storage unit, and reprogrammable, SRAM-based configurable logic unit). Because the configuration data is stored on the DS28E01 decryption chip, and the chip has a mechanism to prevent the storage data from reading, flash-based solutions provide a relatively secure solution. In addition, unless very complex methods are used to invalidate security mechanisms, the likelihood of data corruption is very low.
To prevent the cost of the DS28E01 IC unlock system from soaring, designers must also continue to use encrypted DS28E01-based IC unlock. But they must find a way to protect IP and keep the cost of security measures at the lowest possible level, without having a significant impact on the production process. It is very important for the design to load hardware circuits for DS28E01 decryption security protection into the space allowed by the circuit board without increasing overall power consumption. Moreover, the impact of security on FPGA resources must be as small as possible.

Nowadays, more and more people are familiar with the decryption industry, engineers will pay more attention to the encryption of products, so many encryption chips on the market, such as ATSHA204 series, AT88 series, LKT4100 series, DS28E01 series, Korean ALPU series, TI BQ26100 Wait.
Our company focuses on the research of various encryption chips, the structure and assembly instructions of various singlechip, free disassembly, the successful cases of deciphering all kinds of encryption chips on the market. Recently, we have successfully IC unlock the DS28E01 chip, and welcome the customers to call for consultation.
A brief introduction to DS28E01:
DS28E01 communicate with MCU through 1 single buses. The single bus does not say much, and the time required is very strict, accurate to us level.
DS28E01 has four storage areas:
Data storage (EEPROM) (divided into 4 pages, 32 bytes per page).
Key memory (secret) (8 bytes)
Register pages containing specific functions and user bytes (register page)
Volatile register (scratchpad) (8 bytes)
MCU can read and write scratchpad only through single bus, but can not read and write other storage areas directly.
When writing data to the data memory, carrying the initial key or writing the data to the register page, the data is written to the register first, and then the IC unlock the data from the register to the destination address by the corresponding command.
Working principle:
There is a SHA-160 encryption module inside the chip, which participates in the data format of SHA algorithm in 55 byte format.
These data include 8 byte keys, 5 byte user specified random numbers, 32 byte EEPROM content, 7 byte ROMID, 2 byte fixed data (0xFF) and 1 byte EEPROM address TA1.
MCU can read the 20 byte hash value encrypted by the chip through SHA, and compare it with the hash value calculated by MCU itself through the same algorithm.
Since MCU wants to perform the same encryption operation, it must generate the 55 byte message exactly the same as the chip itself. How did it come from?
The 8 byte key is generated and written in itself. ->OK
The 5 byte random number is written to the register before the chip executes SHA. ->OK
The 32 byte EEPROM data will return the 32 byte content before the 20 byte hash value is read back. ->OK
7 bytes ROMID, you can read the ROMID. ->OK of the chip at any time.
2 bytes fixed value, see the handbook to know ->OK
1 bytes TA1, write it yourself. ->OK
Typical application process:
Process 1: initialize the DS28E01 key
The initialization key only operates in the factory before the product is produced, and only needs to be operated once.
Program flow:
1. read chip ROMID
2. generate a unique 64 bit key through a certain algorithm, ensuring that the keys generated by each motherboard are different.
3. write the key to the chip temporary storage area and read back to verify that the write is correct.
4. execute the chip loading key command, so that the chip saves the 64 bit key in the temporary storage area to the key storage area.
5. complete.
Process two: verify the DS28E01 key
The authentication key is carried out in the product application, and every time the product is started, it will verify the correctness of the DS28E01 key.
Validation is normal, and verification is incorrect, and the product is not working properly by certain means.
Program flow:
1. read chip ROMID
2. generate the 64 bit key through the same algorithm in the initialization process.
3. write 8 byte random numbers (only 5 bytes) to the chip temporary storage area, and read back the validation.
4. encrypting the authentication command to the chip, it can read back 32 byte EEPROM data and 20 byte hash value.
5. read data on top, generate 55 byte summary message, and perform SHA1 operations.
6. compare the calculated hash values with the hash values read from the chip.
