Speaking from online banking passwords
First ask you a question, how many digits is your online banking password? You may also need to index by hand? More and more people are using online banking and shopping online, and the cybercrime rate is growing rapidly. People's awareness of network security is gradually increasing (for example, increasing password complexity), making many enterprises (such as social networking sites) have higher requirements for data security. For example, Facebook supports HTTPS protocol encryption. All Google searches use SSL to encrypt all messages and upgrade to a 2 048 bit key. The “Prism Gate†incident also makes some sensitive departments (such as banks, government and defense) more stringent in their data security requirements.
For the current network security needs, the market is in need of high-performance, cost-effective and low-power security co-processors, but few vendors have entered the field. Freescale, with its leadership in communications processors and 30 years of embedded security R&D investment, has introduced the C29x high-performance crypto coprocessor, which includes the C291, C292 and C293 products, which are scalable and Pins are compatible with each other. The C29x crypto coprocessor provides security and scalability for the data center's dramatically increased processing data volume and is optimized for public key processing operations in enterprise and data center network infrastructures.
The "gate god" of network data security
The internal block diagram of the C29x is shown in Figure 1, which integrates Power Architecture e500-v2 core, 32 bit DDR3/3L, 512 KB platform SRAM, security engine (SEC), security monitor, flash controller, and fuse security processor. And a variety of high speed I / O.

The C29x features the following: up to 32k RSA 2 048-bit private key processing performance (C293), up to 12Gbps AES-HMAC-SHA-1 bulk encryption (system throughput); power as low as 5 W (C291) Support two usage modes, including sharing public key transactions (no external storage space, as shown in Figure 2 (a)) and security key management mode (as a transaction sharing accelerator, can also work independently, as shown in Figure 2 (b) Shown). This feature of the C29x is very important, making it suitable for single or multi-chip PCI-E endpoint card configurations or as a standalone processor. The public key per second can run more than 120K RSA 2,048 times, which is three times the performance of the more expensive PCI-E solution offered by market share leaders.

The above security features of the C29x are also attributed to Freescale's trusted architecture, which features secure boot, tamper detection, and a battery backup key to ensure code integrity through a trusted boot process. The hardware state diagram of the safe boot is shown in Figure 3. From the red part of the figure, we can see the rigor of the security boot. Does it make you feel that the C29x has the function of "God" in football?

The best choice for upgrading encryption
Today's IP security protocols, SSL (now upgraded to TLS), and Network Access Control (NAC) are ubiquitous. Both asymmetric keys (public keys) are used for authentication and key exchange, while public keys rely on a large amount of CPU computation. The National Institute of Standards and Technology (NIST) proposed to upgrade from RSA 1 048 bit to RSA 2 048 bit encryption. In fact, the RSA 1024 bit key has been gradually phased out in 2013, while the RSA 2 048 bit key requires 4 times. The above computing power. The scalable security coprocessor is expected to play an important role in a range of applications for network security. Freescale's C29x family is scalable in both power and performance. The C29x is designed to accelerate RSA (up to 4k key size), Diffie Hellman and Elliptic Curve Cryptography (ECC) algorithms. Whether applied to large data center blades or hardware security modules, the C29x crypto coprocessor is thermally limited. Lowest power consumption.
Public key algorithms such as RSA, Diffie Hellman, and ECC are the foundation of digital signature and key exchange protocols, making secure transaction processing a reality. By speeding up public key processing, the C29x family of devices allows the network to scale more efficiently with traffic spikes such as SSL and IPsec that require public keys. It is very difficult to scale based on the number of security transactions, because if the public key matching is performed in software, the processing power of the general purpose processor is quickly exhausted. Optimized for public keys, the C29x family of devices accelerates AESâ€HMACâ€SHAâ€1 bulk encryption tasks and integrates bulk encryption up to 12Gbps.
What was emphasized before is only network security, and this is only one aspect of the current network situation. Another major trend is the explosive growth of data volume, especially mobile data. Cisco's 2013 forecast indicates that global mobile data traffic will grow 13 times in the next four years. The Cisco Global Cloud Index (2012-2017) predicts that global cloud traffic will grow at a compound annual growth rate of 35%. Using the C29x crypto coprocessor with Freescale's QorIQ T-series communications processors (such as the T2080 and T4240 series) will ensure the security of the big data era and achieve both "fish" and "bear paw".
