Prefix Puncturable Signatures with Smaller Signing Key from HIBS
Masayuki Tezuka, Keisuke Tanaka
Puncturable signatures, proposed by Bellare et al. (EUROCRYPT 2016), allow a signing key to be punctured (updated) so that it loses the ability to sign particular messages while re…
Public Key Encryption with Equality Test from Tag-Based Encryption
Masayuki Tezuka, Keisuke Tanaka
Public key encryption with equality test (PKEET), proposed by Yang et al. (CT-RSA 2010), is a variant of public key encryption that enables an equality test to determine whether tw…
Ordered Multi-Signatures with Public-Key Aggregation from SXDH Assumption
Masayuki Tezuka, Keisuke Tanaka
An ordered multi-signature scheme allows multiple signers to sign a common message in a sequential manner and allows anyone to verify the signing order of signers with a public-key…
1-out-of-n Oblivious Signatures: Security Revisited and a Generic Construction with an Efficient Communication Cost
Masayuki Tezuka, Keisuke Tanaka
1-out-of-n oblivious signature by Chen (ESORIC 1994) is a protocol between the user and the signer. In this scheme, the user makes a list of n messages and chooses the message that…
