How to Make the Cramer-Shoup Cryptosystem Secure Against Linear Related-Key Attacksrve the outcomes of the cryptosystem under these modified keys. Cramer and Shoup (CRYPTO 1998) proposed the first practical public-key encryption scheme proven to be secure against adaptive chosen-ciphertext attacks in the standard model. The scheme (CS-PKE for short) has great influence since it em

Identity-Based Blind Signature from Lattices in Standard Modelcan check that whether the signature is indeed generated by the signer, and the signer cannot recall the signing situation. This property is essential when the signed message needs privacy protection for the user, like a bank bill or a trade secret. Lattice-based system is the most promising quantum

Cryptanalysis of a Homomorphic Encryption Scheme Over Integersthe public key size is large. After DGHV scheme was proposed, many variants of DGHV schemes with smaller public key size were proposed. In this paper, we present a multi-ciphertexts attack on a variant of the DGHV scheme with much smaller public key (abbreviated as .), which was proposed by Govinda
