Parallel Key-Insulated Public Key Encryption Without Random Oracles
Abstract. Key-insulated cryptography is a crucial technique for protecting private keys. To strengthen the security of key-insulated protocols, Hanaoka, Hanaoka and Imai recently i...

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...

Strongly Unforgeable Signatures and Hierarchical Identity-Based Signatures from Lattices without Random Oracles
Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...
