MAXQ1061

DeepCover cryptographic controller, MAXQ1061

DeepCover® embedded security solutions cloak sensitive data under multiple layers of advanced physical security to provide the most secure key storage possible. 

DeepCover cryptographic controller (MAXQ1061) protects the confidentiality, authenticity and integrity of software IP, communication and revenue models. It is ideal for connected embedded devices, industrial networking, PLC, and network appliances. 

The embedded, comprehensive cryptographic toolbox provides key generation and storage up to full SSL/TLS/DTLS support by offering a high level of abstraction. It can also serve as a secure bootloader for an external generic microcontroller. 

A flexible file system manages access rights for the objects. The device is controlled over an SPI or I²C interface. *

Cryptographic algorithms supported by the device include all main signature schemes and digest algorithms.  A separate hardware AES engine over SPI, allows it to function as a coprocessor for stream encryption.*

The advanced physical, environmental and logical protections, are designed to meet the stringent requirements of FIPS and Common Criteria EAL4+ certifications.
