Cryptographic-equipment-oriented energy leakage acquisition method and system

Abstract

The invention discloses a cryptographic-equipment-oriented energy leakage acquisition method and system, belonging to the technical field of information security. The method disclosed by the invention comprises the following steps that: (1) a sampling client-side resolves inputted command information to generate a sampling command sequence and sends the sampling command sequence to a sampling server; (2) the sampling server resolves the sampling command sequence to generate control information and sends the control information to an oscillograph or a cryptographic chip; (3) the cryptographic chip executes the received control information and generates a trigger signal, then, sends the executed result to the sampling server, and sends the trigger signal to the oscillograph; (4) the oscillograph executes the received control information, and carries out energy trace information acquisition on the cryptographic chip according to the trigger signal; and (5) the oscillograph sends acquired energy traces to the sampling client-side through the sampling server. The system disclosed by the invention comprises target equipment, the sampling client-side, the sampling server and the oscillograph. The cryptographic-equipment-oriented energy leakage acquisition method and the cryptographic-equipment-oriented energy leakage acquisition system contribute to the fast, accurate and effective evaluation of the energy analysis attack resistance of a cryptographic algorithm in the physics realization of embedded microprocessing.

Description

technical field [0001] The invention relates to a cryptographic device-oriented energy leakage collection method and system, belonging to the technical field of information security. Background technique [0002] The essence of information security is to protect information resources in information systems or information networks from various types of threats, interference and destruction, that is, to ensure the security of information. According to the definition of the International Organization for Standardization, the meaning of information security mainly refers to the integrity, availability, confidentiality and reliability of information. The foundation of modern information security is cryptography, and cryptographic algorithms are the cornerstone of building modern information security. [0003] According to Kirchhoff's principle, the security of a cryptographic algorithm depends only on the key and has nothing to do with the encryption algorithm itself, so protect...
