Three Part Hybrid Encryption Schema

Efficient hybrid encryption from ID-based encryption

This paper deals with generic transformations from ID-based key encapsulation mechanisms (IBKEM) to hybrid public-key encryption (PKE). The best generic transformation known until now is by Boneh and Katz and requires roughly 704-bit overhead in the ciphertext. We present two new such generic transformations that are applicable to partitioned IBKEMs. A partitioned IBKEM is an IBKEM that provide...

RSA hybrid encryption schemes

This document compares the two published RSA-based hybrid encryption schemes having linear reduction in their security proof: RSA-KEM with DEM1 and RSA-REACT. While the performance of RSA-REACT is worse than the performance of RSA-KEM+DEM1, a complete proof of its security has already been published. This is indeed an advantage, because we show that the security result for RSAKEM+DEM1 has a sma...

Fully Homomorphic Encryption - Part II

We continue our discussion on the fully homomorphic encryption scheme of van Dijk, Gentry, Halevi, and Vaikuntanathan [vDGHV10]. Last week we constructed a weakly homomorphic encryption scheme such that for any pair of properly generated ciphertexts c← Enc(b), c� ← Enc(b�), the sum or product of c, c� yields a value that decrypts to the sum (resp, product) of the original underlying plaintexts....

Evolvement of DRM Schema: From Encryption to Interoperability and Monitoring

By reviewing DRMs up to now and two typical examples – AVS DRM and DMP IDP, the paper tries to find out the fundamental challenge of content protection approach from technical and social viewpoints. Not only it is difficult to deploy and update content encryption and security infrastructure, but also the content diffusion is limited and Fair Use is affected. The new schema for DRM should conten...
