Working Principle

The DS28E07+ memory device works on the principle of two-way cryptographic authentication between two devices, called the host and the DS28E07+. Together, the two devices establish a secure connection by exchanging mutually authenticated secret data.

The authentication mechanism employed by the DS28E07+ is based on an established cryptographic technique called the Elliptic Curve Digital Signature Algorithm (ECDSA). This technique requires both the host and the DS28E07+ to generate a set of secret data and then exchange cryptographically signed versions of that data. Once the two devices have mutually authenticated each other, the secure connection is established and data can be transmitted and received.

The DS28E07+ memory device also features a built-in random number generator (RNG) that is used to add an additional layer of security to the authentication process. Whenever the device is powered on, the RNG is used to generate a random number that is used to authenticate the communication between the host and the DS28E07+.

Conclusion

The DS28E07+ memory device offers a secure and reliable connection for a wide range of applications in the industrial, automotive, home automation and medical sectors. Its advanced cryptographic authentication mechanism, combined with its low power requirements, make it an ideal choice for secure and reliable data storage and transmission in demanding environments.
