Normally, there is an expansion of space requirement in visual cryptography. But if one of the two shares is structured recursively, the efficiency of visual cryptography can be increased to 100%. [5] Some antecedents of visual cryptography are in patents from the 1960s. [6] [7] Other antecedents are in the work on perception and secure ...
Secret sharing was invented independently by Adi Shamir [1] and George Blakley [2] in 1979. A demonstration of visual cryptography: when two same-sized binary images of apparently random black-and-white pixels are superimposed, the Wikipedia logo appears
He works in various fields of computer science, mainly the foundations of cryptography. He is notable for initiating research on public key systems secure against chosen ciphertext attack and creating non-malleable cryptography , visual cryptography (with Adi Shamir ), and suggesting various methods for verifying that users of a computer system ...
Adi Shamir (Hebrew: עדי שמיר; born July 6, 1952) is an Israeli cryptographer and inventor. He is a co-inventor of the Rivest–Shamir–Adleman (RSA) algorithm (along with Ron Rivest and Len Adleman), a co-inventor of the Feige–Fiat–Shamir identification scheme (along with Uriel Feige and Amos Fiat), one of the inventors of differential cryptanalysis and has made numerous ...
