The Application Of Quantum Encryption Technology In Audio Information Security

Audio information security refers to the state,and the personal information space,information resources and information carrier that is not affected by various forms,dangerous and threaten,damage,misleading,external mode and internal body.For information security,audio as an important part of information security,the encryption,although the academia has done a lot of research,but most schemes are a misunderstanding,such as encryption of high computational complexity and anti attack ability is weak,the low sensitivity of the key.Audio data encryption is the main component of information security,and the high requirement for encryption of audio data has become the first problem to be solved.Quantum mechanics is a new concept,which has been paid attention and explored by people at present.The encryption process of multimedia information has also been extended to the quantum category.Quantum mechanics is a new method of calculation.Quantum computing uses the superposition and entanglement of quantum mechanics to deal with and convey data information.In this paper,we are going to combine the double random phase encryption method using quantum computation and MP3 coding,because quantum has the unique essence in physics,so it can remedy the deficiency of classical encryption scheme.In this paper,we mainly use the quantum cryptographic algorithm in the digital audio field.The main research results are as follows: we have made a research on the quantum digital audio encryption scheme.Based on MP3 coding and DRPE technology,this paper researches quantum audio encryption algorithm,and introduces parameters suitable for maintaining audio information security in this algorithm,so as to achieve the purpose of ensuring information security.In this paper,the quantum encryption process is as follows: first data processing using MP3 encoding and DRPE issued the audio information security simulation file information,to represent data using quantum states in physics,then encrypted using two keys,its purpose is to process audio data in time domain and frequency domain in the leaves of Fu Li.Finally,the encrypted audio data is obtained.In this paper,the audio information is decrypted using the reversibility of quantum.Finally,the performance analysis of the quantum encryption for audio information security is carried out.First,the simulation experiment is carried out on the encryption scheme in this paper,and then its key sensitivity is analyzed.The key sensitivity of the quantum audio encryption based on MP3 coding is very high.Secondly,the robustness analysis and statistical analysis of the quantum audio encryption and DRPE are carried out respectively.In contrast,the DRPE technology is insufficient and verified.The encryption scheme of this paper has better encryption efficiency and security than DRPE encryption scheme.
