Whitebox cryptography aims to provide security in the whitebox setting where adversary has unlimited access implementation and its environment. In order ensure setting, it should prevent key extraction attacks code-lifting attacks, which steals original cryptographic instead of key, utilizes as a big key. Although recent published ciphers such SPACE, SPNbox, Whiteblock successfully achieve agai...

Cryptography is the technique of changing data or information into unreadable for unauthorized persons. In cryptography process information transfer from sender to receiver in a manner that prevents from unauthorized third person. There are so many cryptography methods are available which based on number theory. The cryptography based on number system has some disadvantages such as large comput...

Quantum cryptography (or quantum key distribution) is a state-of-the-art technique that exploits the properties of quantum mechanics to guarantee the secure exchange of secret keys. This self-contained text introduces the principles and techniques of quantum cryptography, setting it in the wider context of cryptography and security, with specific focus on secret-key distillation. The book start...
