Network of things is expanding day by day, with that security, flexibility and ease of use became concern of the user. We do have a different technique to full fill user’s demands. Some of them are: Single Sign On (SSO), Cryptography techniques like RSA-VES, Serpent etc. In this paper an effort is made to provide all mentioned facilities to the user.

Single Sign On (SSO) authorizes user only once and allow user to access multiple services and make the system very easy to use and also provides flexibility to use multiple programs or applications. The combination of cryptographic algorithms: Serpent (symmetric encryption) and RSA-VES (asymmetric encryption) which are known as one of the secured cryptographic algorithms are used with “session time” which makes communication very secure and reliable.
