CLP-620: Security Protocol Accelerator - LTE

The Security Protocol Accelerator – Long Term Evolution (SPAcc-LTE) is a proven, high-performance, cost-efficient security engine targeted at the 3rd Generation (3G) and 4th Generation (4G) wireless broadband 3GPP/LTE/LTE-Advanced technologies.

The SPAcc-LTE is highly configurable and it allows Elliptic’s customers to tailor their designs to address the complex security requirements for mobile networks, platforms and devices.

Secure environments like ARM TrustZone® are a solid foundation for security solutions in Embedded Systems. Elliptic provides versatile embedded hardware and software security solutions, designed for ARM TrustZone users, which range from hardware protocol accelerators and co-processors to platform security, DRM and content protection. The CLP-620 SPAcc is an ideal fit for the ARM TrustZone architecture as it provides a reliable protection mechanism for sensitive data and transactions, and it can be shared simultaneously with secure and application processors.

The wireless broadband market is expanding at an incredible rate. Mobile networks and platforms must support the explosion of wireless devices and applications, and bring all mobility benefits to a huge group of end-users. New technologies like 4G LTE-Advanced (Release 10 and beyond) are being developed to address these challenges. 3G LTE technologies governed by 3rd Generation Partnership Project (3GPP) specifications defined in Releases 7, 8 and 9 are also still applicable to global mobile phone systems and networks.

The CLP-620: SPAcc-LTE engine has been specifically designed to address the security needs for the current and next generation of mobile broadband telecommunications. The security engine reduces the bus traffic and offers increased throughput by supporting efficient data sequencing as well as parallel processing of cryptographic operations (authentication and encryption/decryption).
