Enum Constant Detail

SECURE_MEDIA_PATH

public static final SecurityLevel SECURE_MEDIA_PATH

Equals to L1 in Widevine. The Hardware must provide a secure Bootloader, a secure trust zone, and the key shall never be exposed in clear. The samples are provided encrypted to the rendering core and never exposed in clear.

ROOT_OF_TRUST

public static final SecurityLevel ROOT_OF_TRUST

Equals to L2 in Widevine. The Hardware must provide a secure trust zone, and the key shall never be exposed in clear. A custom Android Bootloader could be provided by the Hardware manufacturer if the required security is met. The samples are provided encrypted to the rendering core and never exposed in clear.

SOFTWARE

public static final SecurityLevel SOFTWARE

Equals to L3 in Widevine. The key may be exposed in clear on the CPU, the Hardware does not need to protect the content. The Decryption happens in software, and the samples are passed to the rendering core in clear.

Method Detail

values

public static SecurityLevel[] values()

for (SecurityLevel c : SecurityLevel.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static SecurityLevel valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
