Sharing Notice: White The National Cryptographic Standards Executive Summary As per the mandate of the National Cybersecurity Authority (NCA) that was issued by the Royal Order number 6801, dated October 31, 2017, the NCA is mandated to draft the national cryptographic policies and standards, to ensure compliance with these standards and policies, and to review and update them periodically. From this perspective, the NCA has developed the National Cryptographic Standards (NCS –1:2020) to prescribe the minimum acceptable cryptographic requirements for civilian and commercial purposes to protect national data, systems and networks. This document highlights the details of the national cryptographic standards, which are composed of two strength levels: MODERATE and ADVANCED. This standards document prescribes the accepted symmetric and asymmetric primitives, symmetric and asymmetric schemes, some of the accepted common application protocols related to cryptography, Public Key Infrastructure (PKI) and Key Lifecycle Management (KLM). It further presents appendices that include some considerations regarding Pseudo Random Number Generation (PRNG), Post-Quantum Cryptography and Side-Channel Attacks. 8 Document Classification: Open
