Analysis on Aigis‐Enc: Asymmetrical and symmetrical
Aigis‐Enc is an encryption algorithm based on asymmetrical learning with errors (LWE). A thorough comparison between Aigis‐Enc (with the recommended parameters) and a symmetrical LWE encryption scheme on the same scale (the sampling parameters are {η1 ...

CQTRU: A Commutative Quaternions Rings Based Public Key Cryptosystem [PDF]
In this paper, we propose a new version of the NTRU public key cryptosystem called CQTRU. It is a four-dimensional cryptosystem based on the commutative quaternion ring.

Exploiting Decryption Failures in Mersenne Number Cryptosystems
Mersenne number schemes are a new strain of potentially quantum-safe cryptosystems that use sparse integer arithmetic modulo a Mersenne prime to encrypt messages. Two Mersenne number based schemes were submitted to the NIST post-quantum standardization process: Ramstake and Mersenne-756839.

On Symmetric Encryption with Distinguishable Decryption Failures [PDF]
We propose to relax the assumption that decryption failures are indistinguishable in security models for symmetric encryption. Our main purpose is to build models that better reflect the reality of cryptographic implementations, and to surface the security issues that arise from doing so.

The Impact of Decryption Failures on the Security of NTRU Encryption [PDF]
NTRUEncrypt is unusual among public-key cryptosystems in that, with standard parameters, validly generated ciphertexts can fail to decrypt. This affects the provable security properties of a cryptosystem, as it limits the ability to build a simulator in the random oracle model without knowledge of the private key.

Ciphertext policy hidden access control scheme based on blockchain and supporting data sharing
Objectives: Although the traditional attribute-based encryption scheme achieves one-to-many access control,there are still challenges such as single point of failure,low efficiency,no support for data sharing,and privacy leakage.To solve these problems,a

Rogue Decryption Failures: Reconciling AE Robustness Notions [PDF]
An authenticated encryption scheme is deemed secure AE if ciphertexts both look like random bitstrings and are unforgeable. AE is a much stronger notion than the traditional IND---CCA. One shortcoming of AE as commonly understood is its idealized, all-or-nothing decryption: if decryption fails, it will always provide the same single error message and ...
