Abstract. Based on chaotic biological cryptography and computer-generated holography, a symmetric–asymmetric hybrid encryption and decryption system was proposed. This method has multiple keys, in which two decryption keys are different from the encryption keys. The encryption and decryption system possesses both symmetric and asymmetric key cryptography features. The biometric code is unique and unchangeable, not easy to be stolen or lost, which further enhances the security of the system. Chaos technology can reduce the amount of information, when combined with the advantages of the digitization of computer-generated holography, which can be conducive to the preservation and the transmission of encrypted information. The numerical simulation results show that this scheme is feasible and has better security and higher robustness.

基于混沌虹膜相位掩模和计算机全息的对称-非对称混合加解密系统

摘要。基于混沌生物密码学和计算机生成全息术，提出了一种对称-非对称混合加解密系统。该方法有多个密钥，其中两个解密密钥与加密密钥不同。加解密系统同时具有对称和非对称密钥密码学特征。生物识别码唯一且不可更改，不易被盗或丢失，进一步增强了系统的安全性。混沌技术可以减少信息量，结合计算机全息数字化的优点，有利于加密信息的保存和传输。数值仿真结果表明，该方案是可行的，具有较好的安全性和较高的鲁棒性。
