Cryptography is the field that uses mathematical techniques to secure information. The rapid rise of computer and communications technology, especially the widespread use of the Internet, has greatly increased the demand for such techniques. For example, trillions of dollars of currency exchanges are carried out each day, and these must be encoded in such a way that malicious parties cannot view or tamper with them (even if they are sent over publicly accessible networks). Symmetric-key cryptographic primitives such as block ciphers, hash functions, and stream ciphers are fundamental components of the infrastructure that enables such transactions to be carried out securely and efficiently.

密码学是使用数学技术来保护信息的领域。 计算机和通信技术的迅速崛起，特别是互联网的广泛使用，大大增加了对这种技术的需求。 例如，每天进行数万亿美元的货币兑换，这些货币兑换必须以恶意方无法查看或篡改的方式进行编码（即使它们是通过公共可访问的网络发送的）。 对称密钥密码原语（如块密码、散列函数和流密码）是基础设施的基本组成部分，使此类交易能够安全有效地执行。
