Identity-based Threshold Signature Secure in the Standard Model
Recently, design of Identity-based (ID-based) threshold signature schemes which are efficient and provably secure in the standard model has drawn great concerns. In this paper, an...

Unidirectional Chosen-Ciphertext Secure Proxy Re-Encryption
Abstract. In 1998, Blaze, Bleumer, and Strauss proposed a cryptographic primitive called proxy re-encryption, in which a proxy transforms – without seeing the corresponding plain...

Efficient Certificateless KEM in the Standard Model
Abstract. We give a direct construction of a certificateless key encapsulation mechanism (KEM) in the standard model that is more efficient than the generic constructions proposed ...

New Fuzzy Identity-Based Encryption in the Standard Model
In a fuzzy identity-based encryption (IBE) scheme, a user with the secret key for an identity ID is able to decrypt a ciphertext encrypted with another identity ID if and only if I...

Mechanisms and significance of spike-timing dependent plasticity
Hebb's original postulate left two important issues unaddressed: (i) what is the effective time window between pre- and postsynaptic activity that will result in potentiation?...

On the Impossibility of Three-Move Blind Signature Schemes
We investigate the possibility to prove security of the well-known blind signature schemes by Chaum, and by Pointcheval and Stern in the standard model, i.e., without random oracle...

Practical leakage-resilient identity-based encryption from simple assumptions
We provide new constructions of Leakage-Resilient IdentityBased Encryption systems (IBE) in the Standard model. We apply a hash proof technique in the existing IBE schemes of Bone...

Statistical Models of Conditioning
Conditioning experiments probe the ways that animals make predictions about rewards and punishments and use those predictions to control their behavior. One standard model of cond...

Nonlinear Processing in LGN Neurons
According to the current standard model, neurons in lateral geniculate nucleus (LGN) operate linearly. There is, however, ample evidence that LGN responses are nonlinear. To accou...
