Chapter 3: Java Security Components Introduction The purpose of this chapter is to introduce some of the many Java components for security. The difference between the Java components lies in the purpose of the component, the supporting algorithm, and the supporting protocol. In Chapter 1, the operations for security are defined as authentication, authorization, data confidentiality, and data integrity. All Java security components do have similarities based on how they are constructed. 4 provides the Application Programming Interface (API).

Implementations are discussed in more detail in subsequent chapters. Figure 3-1: The association of the API and SPI Categorizing Security Elements Each security operation requires security elements. The security elements change depending on the security operation and algorithms that the security operation uses. Each security operation has a Java API and underlying security mechanism that implements the operation. The security elements define the security operation; for example, if the security operation uses keys, the security operation is confidentiality.

This is called a key pair. See Figure 3-4 for the secret key and Figure 3-5 for the key pair. Figure 3-4: The secret key Figure 3-5: The key pair The key pair requires both the private and public key to encrypt and decrypt the message or data. Only the public key from the associated private key can decrypt the message. No other public key can decrypt the same message. 509 certificate. 509 certificate can be stored in an unsecured key store because the certificate itself contains a public key. Following the path of the certificate can only decrypt the public key.
