چکیده
During the SA3-31 meeting in Munich, it was decided that the Bluetooth link between peripheral devices did not require integrity protection (see section 6.1.1 of [1]). This contribution indicates that a man-in-the-middle attack may be possible on the bluetooth link in a WLAN in-terworking environment. The attacker lures the victim to connect to a malicious WLAN access point. The attack does not require to know the Bluetooth link key. The attacker can repeat this attack on the same victim many times in any WLAN network. A discussion of countermeasures against this attack can be found in a companion contribution [2].

متن کاملTumor necrosis factor-inducible gene 6 protein: A novel neuroprotective factor against inflammation-induced developmental brain injury
Inflammation is an important factor contributing to developmental brain injury in preterm infants. Although tumor necrosis factor-inducible gene 6 protein (TSG-6) has immunomodulatory effects in several inflammatory conditions of adult animals, nothing is currently known about the role of TSG-6 in the developing brain, its impact on perinatal inflammation and its therapeutic potential. The aim ...
متن کاملTSG-6 controls transcription and activation of matrix metalloproteinase 1 in conjunctivochalasis.
PURPOSE To investigate the role of anti-inflammatory TSG-6 in controlling MMP-1 and MMP-3, which have been shown to be upregulated in conjunctivochalasis (CCh). METHODS Immunostaining of TSG-6 was compared between normal and CCh conjunctiva and Tenon's capsule. Second cultures of normal and CCh fibroblasts were transfected with or without TSG-6 siRNA and then with or without the addition of T...
