DeepCover solution looks to provide enhanced protection for electronic devices

New from Maxim Integrated the DeepCover Secure Authenticator (DS28C22) is a highly secure cryptographic solution for a host controller to authenticate peripherals or embedded designs, and it offers encrypted communication as an added benefit. DeepCover has been designed to help embedded security solutions protect sensitive data with multiple layers of advanced physical security and provide highly secure storage of the authentication secret keys.

Using the FIPS 180 based SHA-256 authentication algorithm, the DS28C22 combines crypto-strong, bidirectional, secure challenge-and-response authentication with small message encryption. Through bidirectional authentication, the host and the peripheral authenticate one another, protecting the IP in the peripheral from a non-authentic host trying to modify operation of the peripheral.

The DS28C22 enables an improved level of security for many applications, including peripherals/disposables, sensors, network equipment, IP licensing, and industrial applications like programmable logic controllers (PLCs).

A bidirectional security model enables two-way authentication and encryption between a host system and slave-embedded DS28C22. Strong die-level protection securely stores the authentication key.

DeepCover has been designed to be both simple and totally programmable. It Includes 3K bits of user memory with four user-programmable modes of protection; an SHA-256 option enables customers to securely control end-product features through data settings.

Maxim is able to offer an optional DS28C22 preprogramming service that prevents supply chain vendors from compromising a solution and ensures no exposure of cryptographic keys.

The DS28C22 also includes a dedicated hardware-accelerated engine for SHA computations.
