Abstract

The present application discloses an information processing method based on the RSA algorithm. The information processing method includes, when an information processing instruction is received, determining the target information m, the modulus n, the private key d, the first prime number p and The second prime number q; perform mask processing on the target information m to obtain mask information m', perform blind operation-based modular exponentiation on the mask information m' according to the first prime number p and the second prime number q to obtain the first processing result and the second processing result; when the power exponent of the first processing result and the second processing result is 0 or 1, perform a corresponding consistent processing operation so as to add random noise; according to the first processing result and the second processing result after adding random noise 2. Processing the result to generate a decryption result or a signature result of the target information. The method can effectively defend against side channel attacks and improve the security of the information processing process. The application also discloses an electronic device, which has the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an information processing method based on an RSA algorithm and an electronic device. Background technique [0002] The RSA public key encryption algorithm was developed by Ron Rivest, Adi Shamirh and Len Adleman in 1977. It is a safe and practical public key encryption algorithm. It can be used for both data encryption and digital signature. It is currently the most widely used Extensive public-key cryptographic algorithms. This algorithm has withstood many years of traditional mathematical cryptanalysis, but due to the development of computers and the rise of side-channel attacks, the application of security chips equipped with this algorithm in cryptographic devices is facing serious threats. [0003] At present, the side-channel attack methods for the RSA public key encryption algorithm include simple power analysis SPA, differential power analysis DPA, relative ...
