ABRIDGED DATA SHEET
DS28E15
DeepCover Secure Authenticator with
1-Wire SHA-256 and 512-Bit User EEPROM
General Description
DeepCover™ embedded security solutions cloak sensi-
tive data under multiple layers of advanced physical
security to provide the most secure key storage possible.
The DeepCover Secure Authenticator (DS28E15) com-
bines crypto-strong bidirectional secure challenge-and-
response authentication functionality with an imple-
mentation based on the FIPS 180-3-specified Secure
Hash Algorithm (SHA-256). A 512-bit user-program-
mable EEPROM array provides nonvolatile storage of
application data. Additional protected memory holds a
read-protected secret for SHA-256 operations and set-
tings for memory protection control. Each device has
its own guaranteed unique 64-bit ROM identification
number (ROM ID) that is factory programmed into the
chip. This unique ROM ID is used as a fundamental input
parameter for cryptographic operations and also serves
as an electronic serial number within the application. A
bidirectional security model enables two-way authen-
tication between a host system and slave-embedded
DS28E15. Slave-to-host authentication is used by a host
system to securely validate that an attached or embed-
ded DS28E15 is authentic. Host-to-slave authentication is
used to protect DS28E15 user memory from being modi-
fied by a unauthentic host. The DS28E15 communicates
over the single-contact 1-WireM bus at overdrive speed.
The communication follows the 1-Wire protocol with the
ROM ID acting as node address in the case of a multi-
device 1-Wire network.
