Bypass defense method, device, electronic equipment and readable medium based on sike algorithm

Abstract

The invention discloses a bypass defense method, device, electronic equipment and readable medium based on the SIKE algorithm, including: the SIKE algorithm is used as the key encapsulation algorithm in the session key negotiation stage before the hardware platform performs secure communication; In the process of encrypting the session key, the homology relationship φ needs to be calculated. When calculating the homology relationship φ, the calculation of the kernel (kernel) will perform the operation ker(φ)= <p+dq>, where P and Q are points on the elliptic curve agreed in advance, d is the private key, and P+dQ is the addition operation of points on the elliptic curve; after the calculation of the homology relationship φ is completed, the session key negotiation phase is completed. The present invention is to ker(φ)= <p+dq>The calculation of has been improved, and the improved method conceals the SIKE algorithm in the execution of ker(φ)= <p+dq>Bypass leaks in the process. Common side-channel attack methods have good defense effects.< / p+dq>

Description

technical field [0001] The invention relates to the fields of cryptography bypass energy analysis and the like, in particular to a bypass defense method, device, electronic equipment and readable medium based on the SIKE algorithm. Background technique [0002] Since the Diffie-Hellman (DH) key exchange mechanism was proposed in 1976, the public key cryptosystem has developed rapidly, and public key cryptographic algorithms such as RSA and ECC have been widely used. However, in recent years, with the development of quantum computing technology and the in-depth application of quantum algorithms, people have found that the mathematical problems based on public key cryptography, such as large number decomposition problems, discrete logarithm problems, etc., will be cracked by quantum algorithms within a limited time . When quantum computers are actually implemented, such algorithms will become easy to break and thus become less secure. Therefore, it is very urgent to study cr...
