Key Encapsulation Mechanism-Based Integrated Encryption Scheme (KEM-IES)

The Elliptic Curve Integrated Encryption Scheme ECIES is widely regarded as a practical method and has been adopted by multiple standards. However, the advancement of quantum computing technologies poses potential security risks to ECIES. Therefore, this study proposes a Key Encapsulation...

AEADs/ascon-aead: Plaintext exposed in decrypt_in_place_detached even on tag verification failure

Summary In decryptinplacedetached, the decrypted ciphertext which is the correct ciphertext is exposed even if the tag is incorrect. Details This is because in decryptinplace in asconcore.rs, tag verification causes an error to be returned with the plaintext contents still in buffer. The root cau...

NIST Standardizes Ascon Cryptographic Algorithm for IoT and Other Lightweight Devices

The U.S. National Institute of Standards and Technology NIST has announced that a family of authenticated encryption and hashing algorithms known as Ascon will be standardized for lightweight cryptography applications. "The chosen algorithms are designed to protect information created and...
