In recent years, electronic devices such as laptops, computers, smart mobile phones and other smart electronic devices have greatly increased, and all these electronic devices use one or more processors inside them, which according to the type of architecture of each processor may have different vulnerabilities. In this paper Investigation and evaluation of side channel vulnerabilities based on the vulnerabilities of Intel and ARM processors has been done based on the hierarchical analysis method. Based on the existing vulnerabilities, the attacks have been divided into 6 general categories, which have been evaluated based on indicators such as time, possibility, effectiveness, and cost. Among the 6 attacks investigated, 3 time-based attack, power side channel attack with software measurement and cache-based attack have respectively assigned the most points based on the evaluation criteria and the power side-channel with hardware measurement attack has the lowest score, where the overall mismatch rate is 0.06, which is acceptable. Also, 3 sub-criteria of key (password) recovery percentage, access level and covert channel ability have had the greatest impact on decision options. Finally, in addition to the overall ranking, these options are also scored based on each of the criteria. From the time point of view, the time-based attack and the power side channel attack with hardware measurement have the highest and the lowest priority, respectively, and from the possibility point of view, the time-based attack and the power side channel attack with software measurement have the highest and lowest priority, respectively. Also, from the effectiveness point of view, time-based attack and side-channel power attack with hardware measurement have higher and lower priority, respectively, and from the cost point of view, time-based attack and micro-architecture-based attack have the highest and lowest points and priority, respectively. Next, the risk level of these 6 strategies was scored and ranked using the CVSS parameter. The results of this evaluation show that 3 time-based attacks, micro-architecture-based attacks, and cache-based attacks, respectively, are more dangerous for the victim and will cause the most damage.
