The day when quantum computers will be able to break conventional encryption is rapidly approaching, but not all companies are prepared to implement post-quantum cryptography.

Public and private key cryptography is a powerful solution. The former (asymmetric cryptography) involves a pair of keys that ...

Abstract: This article introduces an ElGamal-based asymmetric updatable encryption scheme, tailored to address the challenges of secure key rotation in cryptographic systems. The proposed solution ...

Abstract: Extensive research has been done on the security of symmetric encryption algorithms in the black-box attack contexts, where the execution platforms are supposed to be secure. Recent studies ...
