Turnkey security for connected devices with cryptographic controller

November 30, 2016 // By Graham Prophet
Maxim Integrated’s MAXQ1061 is configured to reduce design time with a full security and cryptographic toolbox supporting TLS communication. Developers of Industrial IoT (IIoT) and connected embedded systems can design in an added level of trust with the DeepCover cryptographic controller.

Designed to meet Common Criteria EAL4+ requirements, the MAXQ1061 empowers engineers to quickly design security into their products and protect the endpoints of a network. The device integrates a cryptographic toolbox that provides support for a wide spectrum of security needs, ranging from key generation and storage, to digital signature and encryption up to SSL/TLS/DTLS. It can also support secure boot for most host processors. To withstand extreme industrial environments, the MAXQ1061 operates across the -40 to +109C temperature range—the widest compared to other similar products—and is available in TSSOP-14.

 

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 filesystem enabling custom security policy enforcement. Its cryptographic algorithms include 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 hardware AES engine over SPI, supporting AES-GCM and AES-ECB modes, and that can be used to off-load a host processor for fast stream encryption.

 

The device offers full security, and includes TLS/SSL host stack and comprehensive software support, as well as certificates distribution and management; easy to design strong protection into systems. It is a turnkey offering, with no firmware development required. An evaluation kit is available under NDA request: MAXQ1061-KIT#, with pricing starting at $100.00. The MAXQ1061’s unit pricing starts at $2.64 (1,000)
