“…Since then, many variations of self-certified CAE were proposed, for instance, self-certified proxy CAE [18,19] and convertible multi-authenticated encryption scheme [20,21], which can be used in different application situations. Interested readers can refer to these literatures [15,[17][18][19][20][21] for more detailed discussions. Elaborating on the merits inherent in the self-certified public key systems, the authors will propose efficient and computationally indistinguishable self-certified CAE schemes in this paper.…”

Convertible authenticated encryption (CAE) schemes enable the signer to send a confidential message and its corresponding signature to the designated recipient. The recipient can also convert the signature into a conventional one which can be verified by anyone. Integrating the properties of self-certified public key systems, this paper presents efficient and computationally indistinguishable self-certified CAE schemes for strengthening the security of E-Commerce applications. Additionally, we also adapt the proposed schemes to elliptic curve systems for facilitating the applications of limited computing power and insufficient storage space. The proposed schemes are secure against known existential active attacks, satisfy the semantic security requirement, and have the following advantages: (i) No extra certificate is required since the tasks of authenticating the public key and verifying the signature can be simultaneously carried out within one step, which helps reducing computation efforts and communication overheads. (ii) In case of a later dispute, the recipient can convert the signature into an ordinary one for the public arbitration. (iii) The signature conversion can be solely performed by the recipient without additional computation efforts or communication overheads. (iv) The recipient of the signature can prove himself, if needed, to anyone that he is actually the designated recipient.

EDITORIALAdvances in secure and intelligent data processingWith the fast proliferation of various computational paradigms, from Web-based to wireless and mobile computing, intelligent data processing and security have become cross-cutting features of large scale Internet-based system. On the one hand, there is data being generated everywhere, from various sources and heterogenous formats (such as document repositories, business process data, network data, mobile communications data, server logs data, etc.). On the other hand, the nature of the data, the amount, and data sensitivity, among other features, are promoting the combination of intelligent processing with security intelligence to deliver next generation secure and intelligent systems and applications.This special issue brings together high quality contributions in the interleaving research areas of intelligent data processing and intelligent techniques in security data analysis. The papers of the special issues have also identified and discussed the challenges in the field that will lead to new avenues in intelligent processing for secure and intelligent systems and applications.The special issue consists of 13 papers organized as follows. The first five papers [1][2][3][4][5] are devoted to intelligent secure data analysis, encryption, and authentication techniques. The next three papers [6][7][8] present intelligent optimization and data processing techniques, including genetic algorithms, independent component analysis, and evolutionary game theory. The following three papers [9][10][11] deal with data modeling and analysis in wireless, mobile, and Web-based computing systems. The final two papers [12,13] bring intelligent techniques from image processing field.
