The document discusses secure elements in mobile phones which provide security and confidentiality for mobile transactions. A secure element is isolated in the phone's operating system and hardware, and can only be accessed by authorized programs after entering a PIN. Current implementations of secure elements include being embedded in phones, located on SIM cards, or using removable secure element cards. The document proposes solutions for incorporating secure elements in phone memory, SIM cards, or external SD cards to enable encrypted transactions using protocols like NFC, SMS, and HTTPS.
Secure Element Solutions
- 1. Secure Element The component in a mobile phone providing the security and confidentiality required to support various business models (m-gov, mpayment, m-commerce, m-security, etc.) in this environment, is referred to as a Secure Element (SE). The Secure Element is isolated in the phone’s operating system and hardware and can only be accessed by authorized programs. Another layer of security is provided by requiring you to enter a PIN before accessing the Secure Element to transmit your m-credentials during transactions.
- 2. Motivation for Secure Elements Necessary for several Applications: - Payment - Ticketing - Government - Secure Authentication - …. Because it is considered: - Trusted - Secure
- 3. Current Secure Element Implementations – Embedded in Mobile Phone – SIM Based – Removeable Secure Element (SD Card)
- 5. Secure Element Protocols - NFC - HTTP - SMS - Bluetooth
- 6. Security Algorithms - Public Key Infrastructure - RSA - Elliptic Curve Cryptography - Encrypted SMS - Encrypted Instant Messaging - HTTPS (SSL)
- 7. Our Solution Secure Element in: 1) Phone ‘s memory with a specialized App for iOS, Android, BlackBerry, Windows Phone 2) SIM card as JavaCard, SIM Application Toolkit Applet for all mobile phones. 3) External, removeable, SD card with a specialized App for Android, BlackBerry, Windows Phone.
