    Hm. So: Jan 22 -- Arrives from China to Helsinki. Jan 23 -- A domestic flight to Ivalo, checks into accommodation in Saariselkä (a resort village). Jan 28 -- Quarantined in a Hospital in Rovaniemi. They're tracking down 15 persons in particular, suspected of exposure.

    First confirmed case in Finland (Lapland) -- a 32 y.o. Chinese woman who traveled from Wuhan on January 23, according to Finnish news. Here's an English-language piece This ia apparently the 7th case in Europe.

    The thing has a total of 256 gates for three S-Boxes; 194 XORs, 28 XNORs (the other linear gate), and only 34 AND gates.

    Fun exercise in logic optimization; AES, AES inverse, and SM4 S-Boxes differ only in linear layers, so I added SM4 linear top and bottom layers to the Boyar-Peralta S-box. This is for the proposed super-lightweight RISC-V AES/SM4 instructions (parent dir).

    Btw the 46-page report is marked OFFICIAL, which is the lowest level of security controlled information (previously RESTRICTED/CONFIDENTIAL) and is not actually intended for public release. But it's right there on a HMG website; you can probably google for it and find it. oops..

    UK has some 40 security-cleared folks looking specifically at Huawei under a special arrangement. Software quality is apparently not very impressive (hardly surprising). Distinguishing between plain old stupid and malicious is always difficult.. Interesting report.

    The entire island hums in harmonious 50 Hz since no device is in *negative phase*! Alternating current *the way it is meant to be*.

    I thought my dishwasher was broken, but the maintenance guy showed that this "electrical engineer" (me) was defeated by a lil fuse in the *plug*. Britain, where the electrical standards are so great that - You can't mix up the pins when plugging into AC! - Even fuse has a fuse!

    The claim in the FTI forensics report on Bezos’ iPhone that, “due to end-to-end encryption employed by WhatsApp, it is virtually impossible to decrypt the contents of the downloader [.enc file]...” bugged me so much that I coded up how to do it:

    Did my 10 mile Sunday walk in London for a change. The sun came out just a bit as the Chinese New Year celebrations were starting. Notting Hill Gate - Earl's Court - World's End - Battersea - Vauxhall - Westminster - Leicester Square - Chinatown - Piccadilly.

    Btw.. here's a really nice collection of Chinese crypto standards I'd clone it before it's gone -- I have no idea what is the copyright status of these things.

    There it is, indisputable proof. Had to get original GM/T 0002-2012 SM4 分组密码算法 to check its single test vector; SM4 is indeed big endian. By the way, if had to choose a single test triplet for your national cipher, would you set the key and the plaintext to be the same ?

    These public health centers in Finland do your typical general checkups, cuts and bruises, vaccinations etc. I can just imagine my mom going to her center and there being a note on the window "please avoid visits to Health Center due to the Corona Virus suspicion! [sic]" 😅

    I've been to Ivalo, it's 3 hours drive *north* from Rovaniemi where the (nearest) central Lapland hospital is. I bet it's pretty exotic for most people, hence some tourism. But you couldn't find a more isolated location in mainland Europe.

    Two tourists from Wuhan sought medical help in the (extreme) Northern Finnish village of Ivalo in the and have been quarantined in a public health center. Test results expected soon. [Finnish]
