Abstract(in English) | In this paper we design and implement a security mechanizm that improves the security and the ability to share files amongst users using cryptographic system such as identity based encryption scheme(IBE). In basic file operations AES for symmetric encryption is carried out, while the symmetric keys are shared among members in some group provided with a number of IDs. Under the supervision of the administrator setteled in the group, the public key for the gruop is generated. Proxy-keys for delegating decryption right concerning to the public key are distributed among members of the group. This paper presents the efficient method to construct this proxy-key according to the ID obtained by the member operating over the Hybrid Encryption Scheme built up with IBE. Our scheme will lead to be secure in the sence of IND-CCA. |
