DeepCover Secure Authenticator with

1-Wire ECDSA and 1Kb User EEPROM

General Description

DeepCover embedded security solutions cloak sensitive

data under multiple layers of advanced physical security

to provide the most secure key storage possible.

The DeepCover Secure Authenticator (DS28E35) pro-

vides a highly secure solution for a host controller to

authenticate peripherals based on the industry stan-

dard (FIPS 186) public-key based Elliptic Curve Digital

Signature Algorithm (ECDSA). The ECDSA engine com-

putes keys and signatures using a pseudorandom curve

over a prime field according to the “Standards for Efficient

Cryptography (SEC)”. The private and public key can

be computed by the device or installed by the user and

optionally locked. Separate memory space is set aside to

store and lock a public-key certificate as it is needed to

verify authenticity. In addition to ECDSA-related memory,

the device has 1024 bits of user memory that is organized

as four pages of 256 bits. Page protection modes include

write protection, read protection, and one-time-program-

mable (OTP) memory emulation modes. The DS28E35

also features a one-time settable, nonvolatile 17-bit dec-

rement-on-command counter, which can be used to keep

track of the lifetime of the object to which the DS28E35

is attached. Each device has its own guaranteed unique

64-bit ROM identification number (ROM ID) that is fac-

tory 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. The DS28E35 communicates over
