The next generation of mobile phones will have more functional service applications that allow users to accomplish many things that were previously unimaginable. With just one mobile phone, people's shopping, work, and home life will be more convenient. The technical implementation of these functions is not difficult, but without the perfect security system, people will not be able to trust the security and privacy of the device. The strong security provided by flash technology will enable future-proof next-generation mobile phone functions to be implemented more quickly.
Flash technology to protect mobile phones
Today, European consumers can already pay through mobile phones when shopping in certain supermarkets, and even pay for parking through the parking management system. In Japan, people can already use mobile phones to pay for public transportation and small shopping expenses. This kind of mobile payment will make mobile phones become digital wallets in people's daily lives, and thus become an important application in e-commerce and finance.
Flash technology plays a vital role in the security of mobile payments, and payment protocols are completed between mobile phones and sales devices. In mobile phones that implement protection through flash technology, accounts and personal information are stored in a flash memory with security features that only authorized parties can access or operate. In this way, consumers (mobile phone users) can enjoy the convenience of mobile payment more confidently.
The mobile key is another interesting application brought by flash security technology and the next generation of new lifestyles that may be realized in the future through mobile phones. When people rent an apartment, the landlord does not personally hand the key to the renter, but sends an electronic key to the renter via text message and sets a certain validity period. If the house expires, it cannot be used anymore. At the same time, the renter does not need to return the key, and the landlord does not need to change the lock frequently. If the phone is lost during the period, you can get new text messages from your new phone. The key can be encrypted and can only be decrypted with a specific phone, which can be done using the Public Key Exchange Protocol (PKI). The flash itself can do all the encryption and decryption without increasing the processing load on the system.
The security provided by flash memory not only brings a wonderful experience to end consumers, but also brings business opportunities to operators and financial service providers. By seeking stronger security protection measures, operators and service providers can effectively prevent users from being exposed to the threat of malicious viruses, malicious attacks and fraud through the transmission of confidential information on mobile phones, and continuously build user loyalty to new data services. In addition, retailers, banks, and transaction services can increase the volume of transactions, speed up transactions, and reduce fraud with the security provided by flash memory, making it easier to sponsor and fund these new technology transitions.
The key to protecting personal, financial, and corporate information from stolen mobile phones is to ensure that no one other than authorized users can access them. By implementing security technology directly in the built-in flash subsystem, handset manufacturers and service providers can provide a new level of security for mobile phones. The implementation of this security technology enables new protection measures such as shutdown, locking, etc.: When the phone is stolen, the phone can be permanently locked. Mobile phone memory security also means an automatic recovery capability. When online hackers, viruses and malware attack, the phone can automatically recover from the memory. This ability can restore the phone to its original state, so that it can be attacked before it is attacked. All information is effectively protected.
For example, Scransion, an all-flash solution provider, has introduced the industry's first flash subsystem for mobile security to protect mobile phones from viruses, service theft and malicious attacks. MirrorBit MCP with Spansion Secure can be used as a Trusted Execution Environment to support domain segmentation, ensuring that critical data, code and security keys are never compromised. This feature is implemented by some of the most powerful security algorithms, including the Advanced Encryption Standard (AES), a block cipher that has been chosen by the US government as an encryption standard, and Secure Hash Algorithms (SHA). The cryptographic hash function developed by the National Security Agency, including SHA-1 and SHA-2; the RSA algorithm developed for public key encryption; and a digital random number generator.
By placing storage and security features in the same physical package, Spansion provides greater protection for users accessing flash memory and valuable data and content stored in flash memory. The MirrorBit solution, protected by Spansion Secure technology, protects multiple areas of the storage device, such as separate, protected areas for users, carriers, content rights objects, and handset manufacturers, up to 16 such areas . The solution does not rely on operating systems and chips, helping handset designers reduce time to market and reduce development costs. In addition, it supports server-to-memory direct authentication and secure channel communication similar to VPN, enabling enterprises to remotely manage critical data distribution and establish new business models.
Large capacity SIM card
With the continuous enhancement of mobile data functions and multimedia functions, consumers' demand for mobile storage capacity is also increasing. This demand is not only reflected in the demand for the capacity of external memory cards, but also in the demand for SIM card capacity. On this basis, a large-capacity SIM card (HD-SIM card) came into being. Its emergence not only increases the capacity of the SIM card, but also enables consumers to store more information and content in the SIM card. At the same time, it enhances the wireless download capability of digital content, providing operators with new brand content channels and Better protection of distributed media content through digital rights management.
The introduction of cutting-edge flash memory technology has brought a richer user experience to consumers while significantly reducing the cost of storage subsystem materials (BOM) for mobile phone OEMs.
MirrorBit Eclipse solution
After the introduction of proprietary MirrorBit technology, Spansion introduced MirrorBit ORNAND technology and the world's first 4-bit MirrorBit Quad technology per cell, driving the development of flash memory with continuous innovation in non-volatile memory technology. Today, Spansion has introduced a powerful revolutionary MirrorBit Eclipse architecture that delivers higher performance and lower cost for multifunction phones.
The MirrorBit Eclipse solution is targeted at the versatile mobile phone market. According to different standards, the segmentation of mobile phone segments is also different. Spansion divides it into three categories: mainstream mobile phones, high-end multi-function phones and smart phones. The functions of high-end multi-function phones and smartphones are overlapping, both of which present features and features of the other, including shared operating systems, multimedia on smartphones, and personal tools in multi-function phones, such as GPS and map information. Personal financial management. This overlapping trend brings two different architectures: PC and mobile architecture. However, there are currently few satisfactory solutions. PC-type architectures are commonly used on smartphones and high-end multifunction phones to store code and data on NAND and execute code on DRAM. DRAM has poor scalability and is more expensive than NOR flash, even on the same node, which has a huge impact on the cost of mobile phones. By leveraging the advantages of MirrorBit Eclipse's NOR interface and XIP (execute-in-place) operation, handset OEMs can help reduce the amount of DRAM in the system.
Performance improvements through high-speed code execution and storage of large amounts of multimedia content through the MirrorBit Eclipse architecture can be implemented on a single die. The MirrorBit Eclipse architecture is easy to use and compatible with existing platforms, enabling handset OEMs to easily upgrade and quickly bring innovative multifunction handsets to market at a constant or even lower cost, impacting the current industry. Standard price point. At the same time, the complete MirrorBit Eclipse array seamlessly supports fast reads and writes on the same storage unit, breaking the traditional functional requirements of supporting code execution and data storage with different memory chips. MirrorBit Eclipse can achieve longer battery life, or because of the smaller battery size and possibly smaller handset size, further reducing handset costs and increasing OEM and user flexibility.
