In mobile communication, messages are delivered via the air. This may attract hackers to eavesdrop and then break them. Hence, the security is an important issue needed to be addressed. Advanced Standard Encryption (AES) is currently a frequently used encryption approach. However, AES will be insecure in the near future since it has been partially solved. Therefore, in this paper, we present a security...
In this paper, we propose two block cipher modes of operation (BCMO for short), named the Key Stream Protection Chain mode (KSPC for short) and Output Dual Chaining mode (ODC for short), which differ from other existing BCMOs in that in the KSPC, the ciphertext block and in the ODC, the block cipher encryption unit's output are fed back to the encryption system to be one of the inputs of the next...
