OP-TEE: Boot Time Optimized and Performance

Product Description

OP-TEE is a small secure operating system which, after authentication and decryption, gets loaded in an secured area in the memory. A RichOS (for Xilinx Petalinunx) driver can request via a Secure Monitor Call the execution of an trusted application. As OP-Tee sits in on chip memory (OCM or TCM) which is additionally protected by Xilinx Memory Protection Units (XMPU) it is very hard to penetrate this HW wall to inject any malware or get access to keys. Missing Link Electronics took the effort to port OP-TEE to Xilinxs Zynq Ultrascale+ MPSoC Platform. Additionally the typical software implemented features like AES, RSA, SHA3 are replaced by the Hardware Features Of the Zynq Ultrascale+ MPSoC. For your convenience MLE Provides tree Versions of OP-TEE depending on your needs.
