This paper introduced the revolutionary concept of (5) and also provided a new and ingenious method for key exchange. The authors had no practical realization of a public-key encryption scheme at the time.
举一反三
- Symmetric key encryption is also known as: A: public key encryption. B: secret key encryption. C: PGP. D: PKI.
- You administer a SQL Server 2008 instance. The instance hosts a database that is used by a Web-based application. The application processes 15,000 transactions every minute. A table in the database contains a column that is used only by the application. This column stores sensitive data. You need to store the sensitive data in the most secure manner possible. You also need to ensure thatyou minimize the usage of memory space and processor time. Which encryption type should you use?（） A: Symmetric key encryption B: Asymmetric key encryption C: Certificate-based encryption D: Transparent data encryption
- What is the key to the concept of symbol?
- 中国大学MOOC: 以下Pair泛型类public class Pair<K, V> { public Pair(K key, V value) { this.key = key; this.value = value; } public K getKey(); { return key; } public V getValue(); { return value; } public void setKey(K key) { this.key = key; } public void setValue(V value) { this.value = value; } private K key; private V value;}经过类型擦除后，变成以下类public class Pair { public Pair(Object key, Object value) { this.key = key; this.value = value; } public Object getKey() { return key; } public Object getValue() { return value; } public void setKey(Object key) { this.key = key; } public void setValue(Object value) { this.value = value; } private Object key; private Object value;}
