Secure storage for mobile terminals

Mobile terminals acconpanied by open software platforms are increasingly used in legally binding applications, such as payments, votes and content playing and hence, should be secured against thefts, network attacks and malicious programs to achieve public acceptance for their use. Secure storage - a memory area accessible only for authorized entities - is needed to protect users', manufacturers', operators', and content providers' critical data. This paper provides a discussion on requirements and open challenges for secure storage solutions from mobile terminals point of view as well as presents a classification of different techniques for securing mobile data. Furthermore, the paper presents a short survey of existing cryptographic, access control and tamper protected hardware solutions for secure storage
