With the upcoming release of the iphone in England and Germany, Apple have issue a new firmware (1.1.2) that patch the current jailbreak method based on the tiff exploit. A twin firmware for ipod touch was release also. It does not seems to appear that the new apple firmware introduce new features to the iphone. It however according to mac rumor the long time waited functionnaly to add an event in the calendar was added to the touch.
It seem’s that the 1.1.2 firmwae is already broken and the ipod touch is jaibreaked (see the screenshot ) and read this post to know more. Since the new firmware patch the tiff exploit (see endgadget screenshot below) I wonder want exploit is used. Since the jailbreak was so fast it is likely that the team had the exploit ready for many weeks and keep it secret. Thus my bet is it work even on old firemware.
The computer division of the NIST (National Institute of Standards and Technology) have announced yesterday that the successor of the SHA2 will be the winner of an open competition. The same process have been used to select the AES algorithm. This decision is motivated by the recent advance made in hash cryptanalysis (See my previous post on the subject). While SHA-2 is still considered secure, having a competition for it successor is clearly a good thing for the long term.
Winner selection criteria are not (yet) as clear as for AES because the understanding of hash functions leaves a lot to be desired. However I am sure that our understanding will be refined and a precise selection criteria for the competition will arise. If you have idea how to make new hash function, well it is the right time to pull them out
