Abstract

A hypersphere-based multivariable public key encryption/decryption system may include an encryption module and a decryption module. The encryption module may include a processor and a public key transformation component for transforming plaintext into ciphertext. The decryption module may include a processor, a first affine transformation inversion component, a trapdoor component and a second affine transformation inversion component. The trapdoor component may include a linear equation system construction component and a linear equation system solving component. All components may execute corresponding operations, so that a set of data may be obtained finally, and the set of data may be stored and output as decrypted plaintext. If the decryption module does not produce data, the processor may output warning information about a decryption failure to a user.
