_ [電波][仕事] Protection of broadcasting information

　　 I found a FB photo of BLE product that my friend just purchased.　He posted that from the airline lounge in Narita where I was there too. Then I looked around the lounge and found him soon.However, it was really close from my seat where I may receive his BLE beacon.

　　IETF and IEEE agreed to obtain a random MAC address due to the privacy protection last week.

　　I think also the BLE beacon will be security hall of privacy.Some of NFC people said AKM is not required for the NFC because the distance is enough short. Today, even the contact communication such as magnetic tape is broken by skimming.Therefore NFC should be protected by some of AKM as well.

　　So the implementation of random MAC is start of reconsidering for all of broadcasting information.

_ [旅] Abalone　Party

　　I stay in my partner's house in San Jose from today.Tonight we had really nice dinner with Slicon Valey friend.

　　The main dish was fresh abalone which my partner caught the day before yesterday.I never ate such a big and fresh abalone before. In addition, there was the fresh wasabi there for some reason.

　　And very delicious Japanese sake(Dasai) and local beer were given besides.

　　Funny talk with those Silcon Valey friend dressed up the dinner 500%.

　　Thank you very much for all of my friend!
