Information-flow types for homomorphic encryptions
We develop a flexible information-flow type system for a range of encryption primitives, precisely reflecting their diverse functional and security features. Our rules enable e...

Bio-chaotic Stream Cipher-Based Iris Image Encryption
Conventional cryptography uses encryption key, which are long bit strings and are very hard to memorize such a long random numbers. Also it can be easily attacked by using the brut...
