WebThe L-EAP performs such a key generation process as a part of the authentication phase and enlarges the lifetime of the IoMT network. The advanced encryption standard (AES) is improved for providing data confidentiality in L-EAP. The L-EAP improves the confusion property of cipher text in AES and applies shift row and XOR operations to all the ... Webtechniques are suﬃcient to bypass most commercial and open source malware detection techniques, rendering the lack of de-obfuscation fea-tures in tools a vulnerability. This paper focuses on a speciﬁc obfuscation technique, which we call XOR(255). XOR is the exclusive-or binary operation. XOR binary op-erations are performed with “keys.”
