Encryption: a b 1 AES g 2 DES T 3 3DES T [Complete ] Encryption (Encryption setting) Select the encryption method used on the SSL server. 1 In the SSL menu, press U or V to select Encryption. 2 Press [OK]. The Encryption screen appears. 3 Press U or V to move the cursor to the encryption method to be used and then press [OK]. The options available in Encryption are as follows: AES (SSL Server AES setting) AES (Advanced Encryption Standard) was developed to replace DES as the standard encryption as the safety of DES has declined. AES is a block encryption system that uses 128-bit blocks and an SPN structure (a typical structure for repeated encryption) with three selectable key lengths of 128, 192 and 256 bits. DES DES (Data Encryption Standard) is a typical symmetric-key cryptographic algorithm that divides data in to 64-bit blocks and then encrypts each block using a 56-bit key. IMPORTANT Symmetric-key cryptography, because it uses the same key for both encryption and decryption, uses the same key in both directions when encrypted data is exchanged. Accordingly, to prevent the key from being divulged, key transfer and storage must be very strictly managed. 3DES 3DES (Triple Data Encryption Standard) is a high level of encryption in which DES encryption is repeated threefold. SSL: a b 1 Off/On 2 *Encryption [ Exit ] A hash symbol (g ) appears to the right of the selected encryption method. 4 After completing the selection, press [Complete] ([Right Select]). The selected encryption method is set and the SSL menu reappears. Once you have set an encryption method, and asterisk (*) appears in front of this menu option. 4-90 Using the Operation Panel
