Proposed Email System Security based Bio-Chaos Modified Hash and Modified AES

Email messages transmitted over internet can be pose a real threat to the integrity of information, especially if it relates to military matters because it insecure channel. The cryptography achieves confidentiality and authentication to message contents, so must therefore choose efficient algorithm relevant to this field such as algorithm Advanced Encryption Standard (AES) or Data Encryption Standard (DES) as well as biometric recognition and chaotic system In this paper will be using modified AES algorithm, key-bio-chaos that consist from biometric (Fingerprint) and chaotic system (Lu and Lorenz or Lorenz), also uses modified hash function MSHA-768 and MSHA-160/224/256/384/512 in constructing Email system security achieves high level of security and authentication on messages against threats and be easy to use by users, in addition to being compatible with many MailServer
