Abstract-Present era is the information age where information is money and its security is the primary concern. If the organization has faster access to accurate and up-to-date information then correct business decisions can be taken in time to achieve business excellence and uphold an edge over competitors. Various kinds of security mechanisms like cryptography and steganography are extensively employed to keep the information secure and to send it over the network. However cryptography approach is more widely implied than steganography approach because of enhanced security and simplicity. Fundamental goal of any cryptographic algorithm is to provide defence against unauthorized attacks. In this paper, we have proposed a new image encryption algorithm named Stream Encryption Standard for Digital Images (SES) for meeting the requirements of secure image transfer. The results of several experimental and statistical analysis demonstrate that the proposed image encryption scheme provides a proficient and secure way for image encryption. This new algorithm is based on the symmetric key encryption approach.
