DesignWare XSC OTP NVM IP for Secure Encryption Keys

High-definition digital content is driving the need for higher security in the system-on-chip (SoC) devices used to transfer content between consumer devices. The number and types of these devices that store and play video and audio content is skyrocketing.

Digital Content Protection (DCP) is a mechanism for the use of copyrighted content such as movies and music by authorized (licensed) personnel while blocking the use of this content by unauthorized persons. One example of DCP is High-Bandwidth Digital Content Protection (HDCP) for controlling the flow of high-definition video (and audio) from source to display. The HDCP protocol for this transfer comprises authentication of receiving devices, encryption of the content, and procedures to revoke authorization for equipment no longer licensed to receive the HDCP content. Typically, HDCP encryption key storage requirements are just a few kilobytes, but the storage technology has to be low cost, highly secure, field-updatable, non-volatile and very reliable.

In addition to media storage and transfer, secure encryption keys are found in devices such as encrypted flash memory drives, hard disk drives, and electronic point of sale systems.

DesignWare XSC OTP NVM offers the industry’s most secure anti-fuse OTP for security engines and roots-of-trust. With built-in cell level redundancy and uniform power distribution, the OTP in 8 Kbit to 32 Kbit densities offers a robust solution for secure encryption keys.
