—This paper presents an eavesdropper-proof algorithm that is capable of fast generating symmetric (secret) keys. Instead of literally exchanging secret keys, both the sender and ...
A key assignment scheme is a cryptographic technique for implementing an information flow policy, sometimes known as hierarchical access control. All the research to date on key ...
Locks are mechanical fastening devices used on various kinds of objects like doors and vehicles, and they can be released using a certain type of key. They have a long history, fr...
Key exposures, known or inconspicuous, are a real security threat. Recovery mechanisms from such exposures are required. For digital signatures such a recovery should ideally —an...
We improve the best attack on Rijndael reduced to 6 rounds from complexity 272 to 244 . We also present the first known attacks on 7- and 8-round Rijndael. The attacks on 8-round R...
