I saw some discussion recently about using JSON for secured data, and I'm not sure that everyone understands the risks. I believe that JSON is unsafe for anything but public data unless you are using unpredictable URLs. . There are 2 problems. CSRF (Cross Site Request Fogery) allows attackers to bypass cookie based authentication. I blogged about it a while ago. Wikipedia talks about it. CSRF allows you to invoke cookie protected actions on a remote server. It allows Mr. Evil to trick Mrs. Innocent into transferring money from her bank account into his. Far less known perhaps, is the JSON/Array hack that allows a user to steal JSON data on Mozilla and any other platform with a modern JavaScript interpreter. . JSON can introduce vulnerabilities such as XSS, potentially compromising session security and exposing critical information.. CSRF Vulnerabilities, JSON Security Risks, Data Authentication Threats. .

IBM claims to have invented a new encryption algorithm which can encrypt and authenticate data in one step. The algorithm takes advantage of parallel processing hardware, to cut in half the time taken to encrypt data. However, the news has failed to impress everyone. IBM says the algorithm could be used to take some of the load off networks, but Bruce Schneier, the founder of Counterpane Technologies, says the speed-up is insignificant in the greater scheme of things. He invoked Moore's Law, commenting: "It's a factor of two. Wait a year, and you get that speed-up for free." The link for this article located at The Register is no longer available.
