Implementing cryptographic schemes generally pursues two goals, both of which are equally important:

security and efficiency. The efficiency of implementation can be measured based on various properties such as the area required for implementation, speed, latency, and power consumption. Security targets are also defined based on countering physical attacks (especially lateral channel attacks). Implementation of cryptographic algorithms is inherently associated with information leakage about hidden system elements (such as keys). Information leakage takes the form of electromagnetic waves and power consumption and is commonly known as lateral channels. Due to the great importance of lateral channel attacks and also their practical application in breaking the implementation of cryptographic algorithms, the Cyberspace Research Institute of Shahid Beheshti University set up a security assessment of cryptographic algorithms implementation (SAPAR) in 2018. SAPAR Laboratory has two educational and research approaches and is equipped with advanced tools to apply lateral channel attacks to cryptographic algorithm implementations. Laboratory services are as following:

• Security assessment of cryptographic systems against electromagnetic attacks
• Security assessment of cryptographic systems against power attacks
• Strengthen cryptographic systems against lateral channel attacks
• Security assessment of software implementations against attacks based on CPU architecture
