What is VC? • Secret sharing scheme. • Visual Cryptography (VC) was introduced by Moni Naor and Adi Shamir in Eurocrypt (1994). • Used to encrypt written text/ pictures etc in a perfectly secure way. • Decoding is done by human visual system, without any computation. 3. WebThis digital encryption method uses numbers raised to specific powers to produce decryption keys. The negotiation should result in session keys and one bidirectional SA. Phase 1 operates under one of two modes: main mode or aggressive mode. The main mode consists of both parties sending three two-way exchanges equaling six messages in total. china methanol
