| Abstract(in English) | Proxy cryptographic scheme allows to transform a ciphertext computed under Alice's public key into one that can be opened by Bob's secret key without seeing underlying plaintext. This scheme will enable a number of useful applications. This paper presents the method to construct proxy-key for delegating decryption right from Alice to Bob using IBE(Identity-based encryption scheme) and security of this primitive. By using this scheme Administator provide Public Key and delegate decryption right between users. The ability to share files amongst users will be improve. |
