摘要：The security of RFID systems come to be a major subject today, notably for low cost RFID tags. Multiple Cryptographic algorithms were proposed to insure the information security and in the same time respect the resource-constrained RFID systems (limited computational, storage capability). In this paper, we proposed a hybrid encryption approach as symmetric key encryption that generate the key dynamically, together with integrity check factors. The key stream generation step follows the chained method, starting from the initial pre-shared key. The approach uses logical operations on intermediate cipher texts and intermediate Keys generated in each stage (named derive function), to generate successive keys. This is improving the chaining technique which use only cipher text to generate the successive keys. Finally, our approach will diminish the computational complexity as well as improve performance.
