Among multi-user cryptography, multi-decrypter encryption shows its particular applications. In multi-decrypter encryption, a message encrypted under multiple decrypters can only be decrypted when all the decrypters cooperate. However, the decryption fails if one of these decrypters can not access to the Internet. In this letter, we propose a simple method to ensure the decryption be successful when some of these decrypters are not online by using proxy re-encrypton. Considering the typical appliction of multi-decrypter encryption, our method seems more valuable.
Keywords:multi-decryptor encryption;proxy re-encryption;applications
