A High Level of Attack Resistance

Achieving PSA Certified Level 3 + Secure Element will enable chip vendors to demonstrate to their OEM customers a high level of protection from physical and software attacks to assets they care about the most – secret crypto keys and crypto functions.

Growing Applicability

Attack methods get more sophisticated every year as advances in hacking equipment come to market. OEMs who need to protect high value systems or protect their brand may want to consider chips that have achieved PSA Certified Level 3 + Secure Element.

Efficient Certification Through Composition – Certify the Trusted Subsystem First

PSA Certified Level 3 + Secure Element builds on a Secure Element (aka Secure Enclave when on chip) that has achieved a PSA Certified Level 4 iSE/SE certificate. The crypto and key storage security functions are tested in the laboratory at a higher Attack Potential (AP=25) and with higher assurance than PSA Certified Level 3.
