Abstract. To be accepted, a cryptographic scheme must come with a proof that it satisfies some standard security properties. However, because cryptographic schemes are based on no...
This paper describes our experiences in the design and implementation of a network for security training exercises, and one such exercise. The network described herein is flexible...
We show that, in the ideal-cipher model, triple encryption (the cascade of three independently-keyed blockciphers) is more secure than single or double encryption, thereby resolvin...
