We propose a fully functional identity-based encryption scheme (IBE). The scheme has chosen ciphertext security in the random oracle model assuming an elliptic curve variant of the computational Diffi...
Hierarchical Identity Based Encryption with Constant Size Ciphertext
Constant Size Ciphertext Based Encryption
2015/8/5
We present a Hierarchical Identity Based Encryption (HIBE) system where the ciphertext consists of just three group elements and decryption requires only two bilinear map computations, independent of ...
We initiate the formal study of functional encryption by giving precise definitions of the concept and its security. Roughly speaking, functional encryption supports restricted secret keys that enable...
In the paper, we propose an H.264 video content encryption scheme, which is based on the analysis of H.264 entropy coding, and has the features of irrelative to individual ciphers and adaptive to digi...
