Description

technical field [0001] The invention relates to a method for generating energy consumption information of an instruction-level cryptographic device, which is used to generate the energy trace (energy consumption value curve) of the host cryptographic device based on a cryptographic algorithm, and the energy trace is used to evaluate the defense of the cryptographic algorithm against energy analysis attacks Capabilities belong to the field of information security technology. Background technique [0002] Side-Channel Attacks (Side-Channel Attacks) refer to the attack method that the attacker cracks the implementation of the cryptographic algorithm through the leakage of additional information generated during the execution of the cryptographic algorithm. In recent years, side-channel attack, as a new type of cryptanalysis method, has attracted extensive attention from the industry and academia, and has developed rapidly. Traditional cryptanalysis regards cipher implementatio...

Problems solved by technology

The traditional evaluation of actual cryptographic devices is quite expensive, because designers cannot evaluate the effectiveness of anti-defense countermeasures during the design process, and insecure defense countermeasures are likely to lead to the re-implementation of the entire development cycle; in the simulation tool With the support, energy analysis attack security detection can penetrate into the design of all levels, which can significantly reduce the development cycle and cost

[0005] However, up to now, there is no energy consumption information generation method suitable for energy analysis attacks, especially the lack of simulation tools with the ability to adapt to multiple energy models and the ability to describe different noise levels

SimplePower and JouleTrack are two typical energy consumption simulators at present. The application objects of the former are compilation optimization and architecture optimization, and do not meet the requirements of energy analysis attacks in terms of noise simulation; the latter claims to provide clock levels for various architectures. energy consumption information, but only C source files can be used as input, and energy consumption information cannot be generated in combination with the architecture of a specific microprocessor
