“…Concluded that finger print based biometrics will be more accurate and affordable among all the biometric techniques, as it doesn't match between individuals and doesn't change with age. So, decided to use finger prints in future work on biometrics, extracting minutiae points from finger prints of a single or multiple users to build access policy and encrypt text or image file using CP-ABE [3], [4], [5]. …”

The biometric based crypto techniques extract the features from grayscale images and use those features in encryption process i.e., key will be generated from extracted features. In attribute based crypto-systems attributes of the user like email, usernames etc.…will be treated as a public key. Secret key is associated with each attribute i.e. for email there will be a secret key and for username there will be another secret key. In biometric based crypto systems, an access policy is built from the extracted biometric features.

“…In this section, the previous CP-ABE schemes [1,2,6,8,9,12,13,24,26,28] with constant-size ciphertexts and the proposed scheme are compared from the aspects of security and efficiency. The ciphertext size of schemes [1,2,6,8,9,12,13,24,28] and ours is 2|G| + |G T | and that of scheme [26] is |G| + |G T |.…”

“…Considering the practical application scenarios where users are resource-constrained with respect to computing power and bandwidth, ABE schemes with low computation and communication costs have received a lot of attention in recent years. The schemes [3,5,19,23] belong to KP-ABE and those in [2,6,8,9,12,13,24,26,28] are CP-ABE. The results in [1] merge the schemes in [3,13].…”

“…Attrapadung et al [2] proposed an inner product encryption with constant-size ciphertexts and the decryption cost is linearly proportional to the number of attributes involved in the access policy. Zhou et al [28] presented a CP-ABE scheme with constant-size ciphertexts and AND * +,− policy while the decryption cost linearly grows with the number of attributes in universe. Although outsourced ABE [11,15,17] can reduce the computation cost of users, the systems have to introduce additional servers.…”

Computationally Efficient Ciphertext-Policy Attribute-Based Encryption with Constant-Size Ciphertexts

et al. 2014

Abstract. Ciphertext-policy attribute-based encryption (CP-ABE) is extremely suitable for cloud computing environment in that it enables data owners to make and enforce access policies themselves. However, most of the existing CP-ABE schemes suffer severe efficiency drawbacks due to large computation cost and ciphertext size, both of which linearly increase with the complexity of access policies. Aiming at tackling the challenge above, in this paper, we propose a CP-ABE scheme which features constant computation cost and constant-size ciphertexts. The proposed CP-ABE scheme is proven selective-secure in the random oracle model under the decision n-Bilinear Diffie-Hellman Exponent (n-BDHE) assumption, where n represents the total number of attributes in universe. In particular, the proposed scheme can efficiently support AND-gate access policies with multiple attribute values and wildcards. Performance comparisons indicate that the proposed CP-ABE scheme is promising in real-world applications, especially for the scenarios where computation and bandwidth issues are major concerns.

Recent technological advances such as the Internet of Things (IoT), fog computing, cloud applications lead to exponential growth in the amount of generated data. Indeed, cloud storage services have experienced unprecedented usage demand. The loss of user control over their cloud stored data introduced several security and privacy concerns. To address these concerns, cryptographic techniques are widely adopted at the user side. Attribute based cryptography is commonly used to provide encrypted and/or authenticated access to outsourced data in remote servers. However, the use of these cryptographic mechanisms often increase the storage and computation costs; consequently, the energy consumption in the entire cloud ecosystem. In this paper, we provide a comparative analysis of different attribute based cryptographic mechanisms suitable for cloud data sharing services. we also provide a detailed discussion of different reviewed schemes, w.r.t. supported features, namely security, privacy and functional requirements. In addition, we explore the limitations of existing attribute based cryptographic mechanisms and propose future research directions to better fit the growing needs of this cloud environment in terms of energysavings, processing and storage efficiency and availability requirements.
