Publicly Verifiable Deletion from Minimal Assumptions
Fuyuki Kitagawa, Ryo Nishimaki, Takashi Yamakawa
We present a general compiler to add the publicly verifiable deletion property for various cryptographic primitives including public key encryption, attribute-based encryption, and…
Public Key Encryption with Secure Key Leasing
Shweta Agrawal, Fuyuki Kitagawa, Ryo Nishimaki +2
We introduce the notion of public key encryption with secure key leasing (PKE-SKL). Our notion supports the leasing of decryption keys so that a leased key achieves the decryption…
Proofs of Quantumness from Trapdoor Permutations
Tomoyuki Morimae, Takashi Yamakawa
Assume that Alice can do only classical probabilistic polynomial-time computing while Bob can do quantum polynomial-time computing. Alice and Bob communicate over only classical ch…
Certified Everlasting Functional Encryption
Taiga Hiroka, Tomoyuki Morimae, Ryo Nishimaki +1
Computational security in cryptography has a risk that computational assumptions underlying the security are broken in the future. One solution is to construct information-theoreti…
