These days, teachers often face classrooms filled with yawning students who stayed up late snapping selfies or playing online games.
Encryption is an important part of the whole securing-your-data package, but it’s easy to underestimate the amount of complexity it adds to any service or device. One part of that is the amount of processing encryption takes — an amount that could be impractical on small or low-end devices. Google wants to change that with a highly efficient new method called Adiantum.
Here’s the problem. While encryption is in a way just transforming one block of data reversibly into another, that process is actually pretty complicated. Math needs to be done, data read and written and reread and rewritten and confirmed and hashed.
For a text message that’s not so hard. But if you have to do the same thing as you store or retrieve megabyte after megabyte of data, for instance with images or video, that extra computation adds up quick.
Lots of modern smartphones and other gadgets are equipped with a special chip that performs some of the most common encryption algorithms and processes (namely AES), just like we have GPUs to handle graphics calculations in games and such.
But what about older phones, or cheaper ones, or tiny smart home gadgets that don’t have room for that kind of thing on their boards? Just like they can’t run the latest games, they might not be able to efficiently run the latest cryptographic processes. They can still encrypt things, of course, but it might take too long for certain apps to work, or drain the battery.
Google, clearly interested in keeping cheap phones competitive, is tackling this problem by creating a special encryption method just for low-power phones. They call it Adiantum, and it will be optionally part of Android distributions going forward.
The technical details are all here, but the gist is this. Instead of using AES it relies on a cipher called ChaCha. This cipher method is highly optimized for basic binary operations, which any processor can execute quickly, though of course it will be outstripped by specialized hardware and drivers. It’s well documented and already in use lots of places — this isn’t some no-name bargain-bin code. As they show, it performs way better on earlier chipsets like the Cortex A7.
The Adiantum process doesn’t increase or decrease the size of the payload (for instance by padding it or by appending some header or footer data), meaning the same number of bytes come in as go out. That’s nice when you’re a file system and don’t want to have to set aside too many special blocks for encryption metadata and the like.
Naturally new encryption techniques are viewed with some skepticism by security professionals, for whom the greatest pleasure in life is to prove one is compromised or unreliable. Adiantum’s engineers say they have “high confidence in its security,” with the assumption (currently reasonable) that its component “primitives” ChaCha and AES are themselves secure. We’ll soon see!
In the meantime, don’t expect any instant gains, but future low-power devices may offer better security without having to use more expensive components — you won’t have to do a thing, either.
Oh, and in case you were wondering:
Adiantum is named after the genus of the maidenhair fern, which in the Victorian language of flowers (floriography) represents sincerity and discretion.

Raising of eyebrows were natural when ex-Rangers player David Robertson decided to take in the reins of a rookie club in Kashmir, but now over a year down the line he knows the risk he took paid off mighty well — “four ready job offers” to be precise.
It was indeed a win-win situation for both — the team and coach. While Real Kashmir FC in May became the first club in the Valley to make into the I-League, for the coach the job offers are coming rather thick and fast.
The Srinagar-based club was started by two friends — Sandeep Chatto and Shamim Meraj — to help the community reeling from devastating floods in 2014.
“For me loyalty is everything. I am here for the cause — for Kashmir. But mind you it is not that only the team is benefiting out of it, when we made into I-League I got four job offers. It is both ways in that matter.
“This team, its players, its owners means a lot to me. I am always there for this team. Of course, the day I feel I am not the best person for the job… I will be the first person to call it quits,” said Robertson, who was a find of a rather famous Scotsman Sir Alex Freguson and had played for Rangers and Aberdeen.
Robertson, thanks to his frowning face and brawny physique, by the look of him is certainly not the friendliest of person to interview.
However, that is only till the time you don’t get to talk to him. Making a perception, that too in a jiffy, can go horribly wrong. And who knows it better than Robertson himself.
He wanted to leave Kashmir as soon he landed here for the first time.
“I had never been to India let alone Kashmir. Also, I thought that Kashmir is hot, like the rest of India. But to my shock when I reached the airport here it was winter time and a day into it there was snow.
“Power cut, no internet… I was ready to go. But then the club owner persuaded me to stay, and now I am so glad that he did that,” he said.
Robertson, who has worked in China and Uganda before, was in New York when an agent got him in touch with Meraj – the co-owner — and before he even knew he was in Kashmir.
Last year when asked to sign the deal, the coach admitted that there was this lingering apprehension back home about Kashmir not being the safest of place.
But that was then, now Robertson calls the place as “safe as any other in the world”.
“Kashmir is lot safer. In fact it is safer than a lot of places in the world. Of course, if you are in wrong place you will be in trouble… and that is true for so many places be it Phoenix, Glasgow.
“The trick is to be sensible and you won’t have any problem here,” he said, adding that had there been any “safety concerns” he would have not called his son Mason from Scotland to play for the club here.
The 23-year-old midfielder had quit Peterhead and joined the club for a full time contract.
“I could watch myself in him when he landed here for the first time. It was different for him as if he has entered some film set of sorts.
“However, the players here made him comfortable. And that was the only concern I had then, I didn’t want anyone to think that because he is my son he is here and that there is any favouritism. If he is good he will play,” he said while reminiscing about the day when his son joined the club.
Soon my wife and daughter will also be coming to the valley, and it will be there first time too, he added.
But to be fair, adjusting to Indian way of life takes time. More so when you are in Kashmir, and the list includes building an appetite for the much-enticing ‘Wazwan’ and putting up with the pan-Indian “poor time keeping”
“Here time keeping is terrible and I tell this to everyone. They pray five times a day. Anyway, this is something that I have come to understand and respect.
“But then there are just so many excuses… one player didn’t make for practice on time because his motor-bike got punctured. Now this thing happened four times in the same month. Yes, for proof he would send me photo of the flat tyre – just that it was the same photo every single time,” he said, barely able to control his laughter.
That said, the players too had their complaints against the coach — what if they tell it in a jocular way.
While veteran midfielder Khalid Qayoom was asked to make an almost impossible sacrifice of the irresistible ‘white-meat balls’ (Gushtaba) for the sake of football, Danish Farooq said the coach, who has little or no knowledge of Hindi language, has somehow picked up Hindi abuses and uses it against them during training.
“Waise woh bol dete hain par unhe matlab kisi ka nahi pata (Yes, he abuses. But he doesn’t know the meaning of any one of them),” said Danish smiling, in his feeble attempt to make up for the damage already done on his part.
But then giving tough competition to the coach’s poor Hindi was one of the local player’s equally — if not more — imperfect English, and senior player Shah Nawaz Bashir cannot help but re-tell one such funny conversation when anyone asks about ‘how’s the communication between coach and players’.
“There is one player – I can’t name – who is not very good with the English language. Once after the match the coach called him and said ‘You dribbled really good. Keep it up for future matches’.
“Now, not able to make head and tail of it, he came to me and asked, ‘Bashir bhai, main sach mein itna bura khela tha? (Brother, did I actually play this bad?),”‘ he said, ensuring this correspondent that he eventually did convey the right meaning.
Last checked, the coach is really working hard on his Hindi. The new words he recently added in the vocabulary includes: Paneer (Cheese) and Alloo (Potato).
Well, till the time it does not spoils the team’s recipe for victory, one does’t see anyone complaining, least of all the people from the Valley.

The Supreme Court on Thursday restored the membership of four legacy cricket associations saying they have made a significant contribution to the cricketing history of the nation. The top court granted permanent membership to the cricket associations of Mumbai, Saurashtra, Vadodara and Vidarbha on the ground that these bodies have produced players of national and international repute. Besides them, a bench headed by Chief Justice Dipak Misra also restored the permanent membership of Railways, Services, and Universities citing their contribution to the game and for nurturing talent.
“These associations have a long and abiding history of nurturing talent for the game of cricket in India. The history of cricket in India is replete with their contribution to the cause of cricket. These associations have produced players who have brought laurels to their states and to the nation.
“The principle of territoriality requires that each of the states and Union Territories should have full membership of BCCI in terms as suggested in clause 3(a)(ii-B). This becomes a principle of inclusion. To utilise territoriality as a basis of exclusion is problematic because it ignores history and the contributions made by the above associations to the development of cricket and its popularity,” the bench said.
The apex court, however, maintained that the decision not to grant the status of full members to the National Cricket Club and the Cricket Club of India as neither of the two clubs fields teams in the Ranji Trophy and they cannot be placed on par with the other state associations. While granting permanent membership to the Services, the court said that it has a long history of association with Indian sports and with cricket as well.
“Having regard to the pre-eminent position occupied by the Services including the Army, Navy and Air Force in propagating the cause of sports and cricket, we are of the view that the same principle which we have followed in the case of Railways should be followed in their case. “Similarly, the Universities are a nucleus for encouraging the game of cricket among players of the college-going generation in the country. We would therefore also grant full membership to the Association of Indian Universities,” the bench said.
