Safety operation method and system based on white box encryption

Abstract

The invention provides a safety operation method and system based on white box encryption. The corresponding encryption algorithm and the decryption algorithm are matched by employing a series of static data as fixed input, lightweight safety operation can be realized, the volume of the static data is small, the operation efficiency is high, and relatively high encryption security can be obtained in a white box attack environment with limited calculating resources.

Description

technical field [0001] The invention relates to the field of network security, in particular to a safe operation method and system based on white-box encryption. Background technique [0002] With the development of technologies such as the Internet of Things and mobile computing, there are more and more scenarios where programs may run in unsafe environments, such as smart phones and tablets picked up or stolen by attackers, captured sensor network nodes, etc. in an unsafe operating environment. The security of cryptographic algorithms and protocols is crucial to ensuring the overall security of information systems. The attack models of traditional cryptographic systems, such as chosen plaintext attack and chosen ciphertext attack, are based on a common assumption that cryptographic algorithms run on secure terminals. Side channel attacks allow attackers to obtain certain leaked information, but are still constrained by a given leak function. In the aforementioned insecu...
