Building and developing pseudo-probabilistics block ciphers, pseudo-probabilistics stream ciphers and key exchange protocols to improve the time complexity and enhance sustainnability and information security before attacks drain detectors.

Research
1) Propose pseudo-probabilistics block cipher protocols and algorithms to solve public-key and shared-key deniable encryption problem to improve the time complexity and enhance sustainnability before attacks drain detectors.
2) Propose pseudo-probabilistics stream cipher protocols and algorithms to solve public-key and shared-key deniable encryption problem to improve the time complexity and enhance sustainnability before attacks drain detectors.
3) Propose post-quantum pseudo-probabilistics commutative encryption protocols by using a hybrid solution of post-quantum commutative encryption with hiden pseudo-probabilistics cipher to improve sustainability before attacks drain detectors.
4) Conduct some experiments to evaluate the effectiveness of the proposed pseudo-probabilistics cipher.
