The security threats of chosen-plaintext attacks on three existing common BCMOs, including the Cipher Feedback mode (CFB), the Output Feedback mode (OFB), and the Counter mode (CTR), are also analyzed. After that, we explain why the OPC mode (or simply the OPC) can effectively avoid chosen-plaintext attacks, and why its security level is higher than those of CFB, OFB, and CTR. %G English %Z TC 5 %Z TC 8 %2 https://inria.hal.science/hal-01480198/document %2 https://inria.hal.science/hal-01480198/file/978-3-642-36818-9_43_Chapter.pdf %L hal-01480198 %U https://inria.hal.science/hal-01480198 %~ SHS %~ IFIP-LNCS %~ IFIP %~ IFIP-TC %~ IFIP-TC5 %~ IFIP-TC8 %~ IFIP-ICT-EURASIA %~ IFIP-LNCS-7804
