Stretchable and self-healable double-network ionogel with strong adhesion and temperature tolerance for information encryption
Ionic liquids Ionogel Double network Fluorescence Information encryption

Recently, hydrogels with adjustable mechanical properties have been developed for information security applications. However, the defects such as easy drying and inferior resistance to extreme tempera...
Using of tiny encryption algorithm in CAN-Bus communication
Tiny algorithm encryption CAN-Bus implement cipher

The rising costs of agriculture machine operation force manufacturers to look for solutions that simplify the machine operation to its users and increase user comfort. However, this trend requires far...
What are the prime factors, or multipliers, for the number 15? Most grade school students know the answer — 3 and 5 — by memory. A larger number, such as 91, may take some pen and paper. An even large...
Tight security bounds for Multiple Encryption
Tight security bounds for Multiple Encryption
2016/1/22
Multiple encryption—the practice of composing a blockcipher several times with itself under independent keys—has received considerable attention of late from the standpoint of provable security.Despit...
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...

Resistant Broadcast Encryption Short Ciphertexts
2015/8/5
We describe two new public key broadcast encryption systems for stateless receivers. Both systems are fully secure against any number of colluders. In our first construction both ciphertexts and priva...

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...

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 ...

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 ...
Circular-Secure Encryption from Decision Diffie-Hellman
Decision Diffie-Hellman Circular-Secure Encryption
2015/8/5
We describe a public-key encryption system that remains secure even encrypting messages that depend on the secret keys in use. In particular, it remains secure under a ``key cycle'' usage, where we ha...
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...
We initiate the formal study of functional encryption by giving precise definitions of the concept and its security. Roughly speaking, functional encryption supports restricted secret keys that enable...
