Abstract

Abstract:

In view of the domain environment in E-documents management, an interoperable cross-domain distribution protocol for E-document is proposed. Based on proxy re-encryption, the scheme uses a semi-trusted entity called proxy server to re-encrypt the document ciphertext without decrypting the ciphertext, such that only users can decrypt the data with his private key. Compared with the existing system, the scheme relieves the server from intense encryption/decryption processing, and achieves reliable decentralized encryption/decryption with good scalability and efficiency.

Key words: re-encryption, multi-domain, E-documents distribution
