They allow user-level and operating system code to define protected private regions of memory, called enclaves. [1] [2] SGX is designed to be useful for implementing secure remote computation, secure web browsing, and digital rights management (DRM). [3] Other applications include concealment of proprietary algorithms and of encryption keys. [4]

KSD-64 "Crypto-ignition keys" on display at the National Cryptologic Museum in 2005. The KSD-64[A] Crypto Ignition Key (CIK) is an NSA-developed EEPROM chip packed in a plastic case that looks like a toy key. The model number is due to its storage capacity — 64 kibibits (65,536 bits, or 8 KiB), enough to store multiple encryption keys.
A Wordlock letter combination lock.. A combination lock is a type of locking device in which a sequence of symbols, usually numbers, is used to open the lock. The sequence may be entered using a single rotating dial which interacts with several discs or cams, by using a set of several rotating discs with inscribed symbols which directly interact with the locking mechanism, or through an ...
In a move or convert operation, zero extension refers to setting the high bits of the destination to zero, rather than setting them to a copy of the most significant bit of the source. If the source of the operation is an unsigned number, then zero extension is usually the correct way to move it to a larger field while preserving its numeric ...

Camellia is a Feistel cipher with either 18 rounds (when using 128-bit keys) or 24 rounds (when using 192- or 256-bit keys). Every six rounds, a logical transformation layer is applied: the so-called "FL-function" or its inverse. Camellia uses four 8×8-bit S-boxes with input and output affine transformations and logical
