Accessing a Network using a Secure Android Application

Security plays a vital role in today's mobile world. There are security issues like sniffing of data while accessing information through open channel. Proper security measures can help to deal with the common security threats faced by mobile phone users such as data protection, privacy, application and personal information security. Cryptographic techniques play an important role in protecting communication links and data, since access to data can be limited to those who hold the proper key. This paper discusses a method to securely access information in a network by an android mobile application using AES cryptographic technique. The paper describes a new key sharing algorithm, based on the symmetric key management, for faster and efficient encryption of data that is suitable for use in a mobile device.
