Abstract
An information security protection method includes: repeatedly substituting a plaintext into an encryption algorithm to obtain a plurality of ciphertexts, and determining whether the ciphertexts are all the same h the processor core. Each time the processor core substitutes the plaintext into the encryption algorithm, the encryption algorithm outputs a ciphertext. When the processor core determines that the ciphertexts are not all the same, the processor core outputs a hacker attack message, which means that an encryption process has suffered a hacker attack.
Claims8
An information security protection system, comprising:
- a processor core, configured to repeatedly substitute a plaintext into an encryption algorithm to obtain a plurality of ciphertexts, and to determine whether the ciphertexts are all the same;
- wherein each time the processor core substitutes the plaintext into the encryption algorithm, the encryption algorithm outputs a ciphertext;
- wherein when the processor core determines that the ciphertexts are not all the same, the processor core outputs a hacker attack message, which means that an encryption process has suffered a hacker attack;
- wherein the number of times that the processor core repeatedly substitutes the plaintext into the encryption algorithm is greater than or equal to two;
- when the processor core determines that the ciphertexts are all the same, the processor core outputs a normal operation message, and the normal operation message represents the normal operation of the encryption process.
