Abstract. The security of cascade blockcipher encryption is an important and well-studied problem in theoretical cryptography with practical implications. It is well-known that dou...
Worldwide symmetric encryption standards such as DES (Data Encryption Standard), AES (Advanced Encryption Standard), and EES (Escrowed Encryption Standard), have been – and some...
The notion of certified encryption had recently been suggested as a suitable setting for analyzing the security of encryption against adversaries that tamper with the key-registrat...
We develop a couple of new methods to reduce transmission overheads in broadcast encryption. The methods are based on the idea of assigning one key per each partition using one-way...
