Identity-Based Hierarchical Strongly Key-Insulated Encryption and Its Application
In this paper, we discuss non-interactive updating of decryption keys in identity-based encryption (IBE). IBE is a public key cryptosystem where a public key is an arbitrary strin...

Universally Anonymizable Public-Key Encryption
Abstract. We first propose the notion of universally anonymizable publickey encryption. Suppose that we have the encrypted data made with the same security parameter, and that the...

Upper Bounds on the Communication Complexity of Optimally Resilient Cryptographic Multiparty Computation
Abstract. We give improved upper bounds on the communication complexity of optimally-resilient secure multiparty computation in the cryptographic model. We consider evaluating an n...

Fast Computation of Large Distributions and Its Cryptographic Applications
Let X1, X2, . . . , Xk be independent n bit random variables. If they have arbitrary distributions, we show how to compute distributions like Pr{X1 ⊕ X2 ⊕ · · · ⊕ Xk} and ...

Parallel Multi-party Computation from Linear Multi-secret Sharing Schemes
Abstract. As an extension of multi-party computation (MPC), we propose the concept of secure parallel multi-party computation which is to securely compute multi-functions against a...
