Handbook of applied cryptography. cn Abstract. This paper presents a new image encryption algorithm based on Chua’s chaos with the combination of baker transformation. First, we divide the original image into blocks with size 8×8 and transform each block into three-dimensional image of binary number with size 8×8×8. Then, preprocess the real chaotic sequences output by Chua’s system and revise grey level of the pixel in three-dimensional image according to sequences value. Finally, use baker’s transformation to scramble image blocks and an encryption image will be obtained by this algorithm.

ReEnc: The probabilistic re-encryption algorithm is run by the CSP. It inputs the public parameters mpk, the receiver’s identity id ∈ ID, an original ciphertext Cid|i ∈ C or a re-encrypted ciphertext Cid|i→k ∈ C that is re-encrypted from the original ciphertext Cid|i , and a time period Tj . It outputs a reencrypted ciphertext Cid|i→j . – IBDec: The deterministic identity-based decryption algorithm is run by a receiver. , dkid|i and dkid|j . It outputs the message m if decryption keys are valid.

From 1990 to 2010, the key length increases almost linearly for [3, 4, 6] (as is easy to see by graphing). However, from 2010 onwards linearity seems to disappear, which raises for us the question of whether the four major factors identified at the beginning of Sect. 2 are still relevant. In fact, the astonishing increase in suggested key size for 2045-2050 in the ECRYPT publications [1, 2] is to deal with the anticipated impact of quantum computing. The three sites [7–9] give recommendations for key length beginning from about 2010; since these recommendations are aimed at governmental and commercial institutions, they take into consideration practical implementations that provide data security.
