چکیده

Abstract


As a special case of public key encryption, identity-based encryption (IBE) takes any public known information as public key for encryption and then decrypts a ciphertext by a well-generated private key from private key generator (PKG). Unlike the traditional IBE using a text-based identity (e-mail, etc.) as public key, in this paper, we aim to design a secure, time-saving and space-saving biometric identity-based encryption (BIBE) regarding the biometric-based identity (face, etc.) as public key. To overcome the challenge introduced by the fuzziness of biometric identities, First, we propose a provable-secure inner-product encryption (IPE) with short ciphertext and show the IPE is indistinguishable against selective identity, adaptive chosen-plaintext attack (IND-sID-CPA). Then, we construct a distance-based encryption (DBE) leveraging the proposed IPE and prove that the DBE captures the same security with the underlying IPE. Furthermore, we optimize the proposed DBE so that it also has short private key. We theoretically analyze the overhead of IPE, DBE, and optimized DBE (ODBE) in terms of time, space, and communication complexities. We also conduct experiments to measure the time and space costs of the proposed ODBE, and experimental results validate its effectiveness and efficiency.

Conclusion


In this paper, we design a biometric identity-based encryption (BIBE) by constructing a time-saving and space-saving distance-based encryption (DBE), where Mahalanobis distance serves as the measurement tool for determining whether two biometrics information belongs to the same user. Leveraging the symmetric property of the covariance matrix, we build a vector transform between the DBE and the inner-product encryption (IPE). We propose an inner product encryption (IPE) scheme that has short ciphertext. Based on the IPE, we construct a provable-secure DBE with short ciphertext. Furthermore, we optimize the proposed DBE such that it also has short private key, the optimized version is called ODBE. We prove that the proposed IPE is secure under selective identity, adaptive chosen-plaintext attack (IND-sID-CPA), and our DBE and ODBE capture the same security with the IPE according to the security reduction. Our theoretical analysis in terms of time, space and communication complexities shows the superiority of the proposed IPE, DBE and ODBE over existing work, and our extensive experimental results validate the theoretical analysis and demonstrate the effectiveness and efficiency of our proposal.
