Abstract
SMS(Short Message Service)plays vital role in day to day life. SMS used in many real world application like Transportation Information System, private health facilities using SMS, mobile banking, participation in elections through SMS, in Crime Scene Investigation and many more.The major problem facing in SMS is security ,while transferring message like account number or password from one user to another user it just taken as a plain text so there some type of attacks like man in the middle attack, disclosure, replay attack takes place and causing a huge risk. The traditional SMS service does not provide information security like confidentiality, integrity, authenticity. The attacker can alter SMS Information using weak encryption algorithm like A5/1 or A5/2.The existing protocol used for providing security in SMS is based on asymmetric and symmetric key. To provide secure end to end communication Easy SMS protocol is used which is completely based on symmetric key. On applying AES algorithm it may provide effective encryption for password. The expecting result on using Easy SMS protocol is to reduce bandwidth consumption and increasing the password or pass code strength through SMS.
