“…In our proposal, multi-dimensional and multichannel optical encryption is realized by manipulating the light field with multiple DoFs, and an asymmetric encryption scheme is exploited, in which both security and capacity are well addressed. As proofs of principle, ciphertext-only attack (COA) 54 , 55 , and known-plaintext attack (KPA) 56 , 57 are employed to evaluate the security performance (detailed in Supplementary Note 7 ), of which the results show that the Stokes meta-hologram can effectively avoid brute force attack and the security level can be increasingly improved by polarization mask, carrier conversion, and eigenstate transformation.…”

Optical cryptography manifests itself a powerful platform for information security, which involves encrypting secret images into visual patterns. Recently, encryption schemes demonstrated on metasurface platform have revolutionized optical cryptography, as the versatile design concept allows for unrestrained creativity. Despite rapid progresses, most efforts focus on the functionalities of cryptography rather than addressing performance issues, such as deep security, information capacity, and reconstruction quality. Here, we develop an optical encryption scheme by integrating visual cryptography with metasurface-assisted pattern masking, referred to as Stokes meta-hologram. Based on spatially structured polarization pattern masking, Stokes meta-hologram allows multichannel vectorial encryption to mask multiple secret images into unrecognizable visual patterns, and retrieve them following Stokes vector analysis. Further, an asymmetric encryption scheme based on Stokes vector rotation transformation is proposed to settle the inherent problem of the need to share the key in symmetric encryption. Our results show that Stokes meta-hologram can achieve optical cryptography with effectively improved security, and thereby paves a promising pathway toward optical and quantum security, optical communications, and anticounterfeiting.

Further, an asymmetric encryption scheme based on Stokes vector rotation transformation is proposed to settle the inherent problem of the need to share the key in symmetric encryption. Our results show that Stokes meta-hologram can achieve highly secured optical cryptography architecture, and thereby paves a promising pathway toward optical and quantum security, optical communications, and anticounterfeiting.

In order to effectively realize the management of educational correction for problem teenagers, improve the security and reliability of encrypted storage of educational correction information for problem teenagers, and shorten the encrypted storage time of educational correction information for problem teenagers, educational correction management for problem teenagers based on information encryption storage method is proposed. Analyze the information encryption storage method and combine it with the necessary theoretical foundation of education and correction of issue teenagers to create an encryption and secure storage management method for education and correction of problem teenagers’ information. The CP-ABE algorithm is used to obtain the initial key of the system, express the encrypted cipher-text, specify the attributes of each user in the problematic youth education and correction user permission list, and obtain the problem youth education and correction user permission control structure. Using tent mapping and cat mapping methods, the key parameters are calculated, respectively, and the encrypted file is piecewise, linearly mapped. Then, XOR is the plaintext bytes and key bytes of the encrypted and safe storage of the problem youth’s education and correction information, completing the encrypted and safe storage of the data information in the problem youth’s education and correction management and realizing the problem youth’s education and correction management. The results of the experiments show that the proposed technology is secure and reliable and that it can efficiently reduce the encryption storage time of educational corrective material for troubled teenagers.
