Microsoft prepares for security in a world where our old codes are easily broken. Get familiar with these technologies now ...

One important aspect of the encryption process is that it almost always involves both an algorithm and a key. A key is just another piece of information, almost always a number, that specifies how ...

• AES (Advanced Encryption Standard): AES is a symmetric encryption algorithm widely used in government and industry. It offers key lengths of 128, 192 and 256 bits, providing strong security.

Software like BitLocker, for example, uses the AES encryption algorithm with 128 or 256-bit keys, making it a great choice for those that value security and privacy. Why encryption matters.

For example, websites use public-key encryption to maintain secure internet connections, so sending sensitive information through websites would no longer be safe.

Let’s follow the RSA algorithm step by step, with an example. Let’s say Bob wants to send a private message to Alice. The first step is for Alice to generate the keys, both public and private.

These two examples are problems that have been studied in number theory since at least the 18th century, yet mathematicians still have not discovered efficient algorithms to solve them.

A New Attack Easily Knocked Out a Potential Encryption Algorithm SIKE was a contender for post-quantum-computing encryption. It took researchers an hour and a single PC to break it.

To stay ahead, the high-tech industry works to develop ever more advanced encryption algorithms and increase encryption key sizes. Classified government information typically needs to remain ...

The PQC algorithm used in the implementation of FIDO2 security keys takes a more cautious approach. It combines the elliptic curve digital signature algorithm—believed to be unbreakable by ...
