We propose a fully functional identity-based encryption scheme (IBE). The scheme has chosen ciphertext security in the random oracle model assuming an elliptic curve variant of the computational Diffi...
Chosen-Ciphertext Security from Identity-Based Encryption
Identity-Based Encryption Chosen-Ciphertext Security
2015/8/5
We propose simple and efficient "CCA-secure" public-key encryption schemes (i.e., schemes secure against adaptive chosen-ciphertext attacks) based on any identity-based encryption (IBE) scheme. When i...
Improved Efficiency for CCA-Secure Cryptosystems Built Using Identity Based Encryption
Cryptosystems Built Identity Based Encryption
2015/8/5
Recently, Canetti, Halevi, and Katz showed a general method for constructing CCA-secure encryption from identity-based encryption in the standard model. We improve the efficiency of their construction...
We present a fully secure Identity Based Encryption scheme whose proof of security does not rely on the random oracle heuristic. Security is based on the Decision Bilinear Diffie-Hellman assumption. T...
Hierarchical Identity Based Encryption with Constant Size Ciphertext
Constant Size Ciphertext Based Encryption
2015/8/5
We present a Hierarchical Identity Based Encryption (HIBE) system where the ciphertext consists of just three group elements and decryption requires only two bilinear map computations, independent of ...
Efficient Selective Identity-Based Encryption Without Random Oracles
Random Oracles Identity-Based Encryption
2015/8/5
We construct two efficient Identity Based Encryption (IBE) systems that are selective identity secure without the random oracle model Selective identity secure IBE is a slightly weaker security model ...
Identity Based Encryption (IBE) systems are often constructed using bilinear maps (a.k.a. pairings) on elliptic curves. One exception is an elegant system due to Cocks which builds an IBE based on the...
Hybrid Radio Frequency and Video Framework for Identity-Aware Augmented Perception in Disaster Management and Assistive Technologies

Identity-Based Parallel Key-Insulated Signature: Framework and Construction
Parallel Key-Insulated Identity-Based Signature Key-Exposure Bilinear Pairings
2014/3/11
To minimize the damage caused by key-exposure in ID-based signatures, in ISPEC’06 Zhou et al (2006) proposed an ID-based key-insulated signature (IBKIS) scheme. However, their scheme is not strong key...
