Maxim releases cryptographic controller, toolbox for connected systems

Maxim Integrated has released the MAXQ1061 DeepCover, a cryptographic controller designed to meet Common Criteria EAL4+ requirements, allowing engineers to design security into their products and protect the network endpoints. The MAXQ1061 is delivered with what the company calls a “cryptographic toolbox,” which enables features such as key generation, secure storage, digital signatures, and SSL/TLS/DTLS encryption. The MAXQ1061 also supports secure boot for most host processors, and no firmware development is required.

The MAXQ1061 embeds 32 kB of user-programmable secure EEPROM for storing certificates, public keys, private and secret keys, and arbitrary user data. The EEPROM is managed through a flexible file system that enables custom security policy enforcement. The device supports cryptographic algorithms including ECC (up to NIST P-521), ECDSA signature generation and verification, SHA-2 (up to SHA-512) secure hash, AES-128/-256 with support for ECB, CBC, and CCM modes, and MAC digest. The MAXQ1061 also provides a separate AES hardware engine over the SPI interface to enable AES-GCM and AES-ECB modes, which can be used to offload encryption functions from a host processor.

“The MAXQ1061 provides a hardware root of trust; its comprehensive set of cryptographic functions fulfill the key security requirements of the embedded systems of tomorrow,” said Christophe Tremlet, Executive Business Manager, Embedded Security, Maxim Integrated. “With the MAXQ1061, our customers have a trusted device that will not only guarantee the integrity and authenticity of the system, but also secure communications.”

The MAXQ1061 operates across the -40° to +109° C temperature range and is available in TSSOP-14. For more information, visit
