Abstract :

To Protect Cyber Security And Privacy, It Is Critical To Design Security And Practical Public Key Encryption Schemes. Today, Big Data And Cloud Computing Bring Not Only Unprecedented Opportunities But Also Fundamental Security Challenges, Big Data Faces Many Security Risks In The Collection, Storage And Use Of Data And Bring Serious Problem Regarding The Disclosure Of Private User Data. It Is Challenging To Achieve Security And Privacy Protection In The Big Data Environment. Thus, To Meet The Growing Demand Of Public Key Encryption In This Environment, We Proposed A Single-bit Public Key Encryption Schemes Based On A Variant Of LPN (Learning Parity With Noise) And Extended It To A Multi-bit Public Key Encryption Scheme. We Provide The Correctness And CPA (Chosen Plain Attack) Security Of The Proposed Method. Our Schemes Solved Encoding Error Rate Problem Of The Existing Public Key Schemes Based On LPN, And The Error Rate In Our Schemes In Negligible.
