- Technical Perspective: What Does Provable Security Mean for Cryptographic Schemes?
Recommendations
Improved convertible authenticated encryption scheme with provable security
Convertible authenticated encryption (CAE) schemes allow a signer to produce an authenticated ciphertext such that only a designated recipient can decrypt it and verify the recovered signature. The conversion property further enables the designated ...
Efficient certificateless proxy signature scheme with provable security
In this paper we propose a very efficient and provably secure proxy signature scheme with implicit certificate (called ''certificateless proxy signature scheme''), where a receiver does not have to verify a certificate before verifying a signed message, ...
On provable security of UOV and HFE signature schemes against chosen-message attack
PQCrypto'11: Proceedings of the 4th international conference on Post-Quantum CryptographyThe multivariate public key cryptosystem (MPKC) is considered to be one of the candidates of post-quantum cryptography. Unbalanced Oil-Vinegar (UOV) scheme and Hidden Field Equation (HFE) scheme are well-known schemes in MPKC. However, little attention ...
