WebVarious security techniques such as watermarking, digital signatures, steganography and cryptography have been widely implemented ... Arun and Murugab [14] proposed combined LSB steganography techniques with XOR substitution operations on RGB images. This method is very simple LSB which is secured by XOR operation with an 8-bit random key. WebFractional-order chaos has complex dynamic behavior characteristics, so its application in secure communication has attracted much attention. Compared with the design of …

Webintroduced a half-gates technique to design free-XOR compatible GRR2. The GRR2, half-gates, and free-XOR garbling schemes improve efﬁciency by leaking locations of XOR gates in the circuit. This kind of information leakage is acceptable for SFE protocols though it maybe be unacceptable for other protocols such as Private Function Evaluation ... WebWe present a secure multiparty computation (MPC) protocol based on garbled circuits which is both actively secure and supports the free-XOR technique, and which has communication complexity O(n) per party. This improves on a protocol of Ben-Efraim, Lindell and Omri which only achieved passive security, without support for free-XOR. somc maintenance openings
