Abstract

The use of cloud system's storage service has been increasing in recent years. A way to secure the stored data is to use cryptographic techniques. One of the techniques that can be used when sharing data accesses with other users, is proxy reencryption, which means converting data from its unreadable form (ciphertext) corresponding to one key into another ciphertext of a different key. Many proxy re-encryption schemes often only use asymmetric key cryptography, and not symmetric key. In this paper we analyze the performance of a symmetric proxy re-encryption scheme's implementation. In measuring the performance of the re-encryption function, the authors compare the running time of the program with that of AES CBC's reencryption's running time, to compare a naïve re-encryption with the selected schemes. We also propose some improvement to the implementation of the proxy re-encryption algorithm.
