March 14, BlackBerry announced and Samsung, IBM cooperation, the launch of a secure tablet computer--secutablet.

March 15, Yahoo at the SXSW conference, the first public demonstration of the new encrypted mail service.

Let's see what SecuTABLET is: Based on Galaxy Tab S 10.5, built-in BlackBerry Secusmart components, install IBM applications, store sensitive data in virtual containers. Business users and Government users can use SecuTABLET to access consumer apps such as YouTube and WhatsApp, while ensuring job-related information security, Bloomberg said.

"For many officials and business executives, work can only be done through safe calls, but a phone call is simply not enough," said the BlackBerry official. "The safety plate was born. "Most importantly, we combine security and usability. We don't want users to lose the fun of life. (Please raise your hand by a reader who has been tortured by a security phone)

For BlackBerry and Samsung, it's important to grasp the niche market for safety after Apple has gone halfway through the mobile electronics market.

Take a look at Yahoo's new encryption service, which is designed to make it easy for ordinary users to send encrypted messages that even Yahoo can't read. After the Snowden incident, the court ordered Lavabit (Snowden used mailbox) to hand over the encryption key. Lavabit refused to hand over the key, so he closed down. Now, Yahoo itself can not read encrypted mail, means that at the technical level can not transfer the user information to the court.

Last year, Yahoo and Google used the same encryption tools, are based on PGP. PGP has never been cracked. The traditional mail provider holds the username and password for the user account, but PGP lets the user store the encryption key on the user's own device.

Yahoo's new encryption tool is significantly faster than PGP. The demo shows that it takes two minutes to send an encrypted message with PGP, and it takes only a minute to use the new Yahoo encryption tool. A Yahoo spokeswoman said that users search for mail more frequently than email, and searching in thousands of encrypted emails is a big project, and speed is very important.

However, the encryption tool is not a panacea, and even if the message is encrypted, it can be traced back. All that is encrypted is the content of the message, the other information is readable, such as the subject of the message, the time of delivery, the sender and the recipient.

The cryptographic service is expected to meet users at the end of the year.
