My (still open question): is there any sample code for AES128 en/decryption? I found DN108 (which covers this topic) is no longer available, what was the problem. Is there any risk if AES128 is used on the CC1110 or CC2510?? Thanks, Jo Jo, As TER said in a different post we ...

This is a proof of concept implementation andshould not be used in a productive environment! For example a lookup table implementation of the addition in GF28is used which is vulnerable to side channel cache attacks.See POC. Example Compile the source code (e.g. using GCC): ...
for(vari =0; i < code.length; i++) { constc = code.charAt(i); if(c ==='%') { consthex = code.charAt(i +1) + code.charAt(i +2); consthexVal =parseInt(hex,16); bytes.push(hexVal); i +=2; }elsebytes.push(c.charCodeAt(0)); } returnbytes; } // 将字符串转为 ASC...

One of the features of AES as implemented in C# is its simplicity. Consider the code inFigure 15that I used to generate the output shown inFigure 1. After declaring hardcoded values for the 16-byte plaintext input and the 24-byte (192-bit) seed key, an AES object is initialized, the...
