Cryptography IV.AThe One-Time Pad Invented by Gilbert Vernam and Major Joseph Mauborgne in 1917, the one time pad is aprovably securecryptosystem. It is alsoperfectlysecure, in the sense that the proof of security does not depend onanyhardness assumptions. In theone-time pad, the message space...
An oracle in the time of the ancient Greeks was a person or place that could communicate with the gods. In cryptography, apadding oracleis a system that provides information about encrypted data without revealing the encryption key. Imagine a web server that encrypts cookies before sending them ...

By addressing the ease-of-use concerns, the modern ciphers in use today such as public key cryptography have seen significant growth in use over the one-time pad. One-Time Pad Key Distribution One of the primary issues when implementing a one-time pad is creating a distribution system that ...
Fortunately, EasyCrypt now features a module system; the module system combines the power of module systems, as they exist in functional programming languages, with a system of capabilities that is used to restrict access to oracles or fragments of memories, as required in cryptography. The module...

time programmability provides the opportunity to write once then read many times. A write once/read-multiple memory may be programmed at a point in time after the memory chip has left the factory. Once the memory is programmed, it may not be rewritten, but it may be read many times. A ...
