Differential fault analysis (DFA) is a type of side channel attack in the field of cryptography, specifically cryptanalysis. The principle is to induce faults—unexpected environmental conditions—into cryptographic implementations, to reveal their internal states.
For example, a smartcard containing an embedded processor might be subjected to high temperature, unsupported supply voltage or current, excessively high overclocking, strong electric or magnetic fields, or even ionizing radiation to influence the operation of the processor. The processor may begin to output incorrect results due to physical data corruption, which may help a cryptanalyst deduce the instructions that the processor is running, or what its internal data state is.
For DES and Triple DES, about 200 single-flipped bits are necessary to obtain a secret key. DFA was also applied successfully to the AES cipher.
Many countermeasures have been proposed to defend from this kind of attacks. Most of them are based on error detection schemes.
After partnering with Wirex, the company was able to add XRP token support to its Visa card. Subsequently, the number of sign-ups and transactions on the platform had a considerable boost.
The very fine qualities of XRP continue to pull users and firms towards itself with the latest addition of Bitcoin Superstore. Earlier this year, Brad Garlinghouse, the CEO of Ripple said the only way of XRP decoupling from Bitcoin influence is through mass adoption.
This movement has supported the saying that the token has more utility than predicted and in fact the firm pushed up ahead and donated millions for humanitarian causes and charity. The first feedback was not that big, however judging from the most recent development Ripple is enjoying the last piece of the cake.
With the above announcement by Bitcoin Superstore via their twitter handle, users can almost in an instant complete settlements with XRP while purchasing from different retail outlets. These outlets being the leading ones like eBay, Amazon and others. If you choose to go for this option remember that XRP in the past has given out results of being cheap for both the merchant offering to accept the token and the user.
Or, even shorter, build a massive, level playing field in which assets can compete to bridge payments, then try to make XRP a winner on that playing field.
This is an ambitious, maybe even crazy, plan. But Ripple has raised tens of millions of dollars, has over a hundred full time employees, and our successes to date speak for themselves. That is, of course, no guarantee of success.
