Key sequence generation for cryptographic operations
Methods, system and devices are provided that generate a sequence of sub-keys for cryptographic operations from a main key. The main key is operated on only once to generate the sub-keys of the sequence, with a transformation comprising one or more one-way functions. The respective bit values of the sub-keys of the sequence are set using respective bit values of the one or more one-way functions. Advantageously, deriving sub-key bits from respective output bits of one or more one-way functions removes or at least reduces correlations between the main key and the sub-keys, as well as between sub-keys, making it harder or even impossible to recover the main key or other sub-keys from a single sub-key, for example as found using a side-channel attack. At the same time, by using the main key only once (rather than using the main key each time a sub-key is generated), the vulnerability of the main key to a side-channel attack is reduced, because the opportunities for recovering physical information that could lead to the discovery of the main key are reduced. Specific embodiments use parallel or chained execution of sub-functions to generate respective sub-keys. Other specific embodiments generate all sub-keys from a single one-way function in one go. |

When two or more of the same special symbols occupy adjacent positions of the playing field, they may merge into a single position occupied by one of the special symbols in question. If three or more special symbols are adjacent, all merge into a single position and a higher-value special symbol. This merge may be signaled by a graphic such as an animation or image, a sound, a light, a vibration, or other audiovisual or haptic indicator. The higher-value special symbol thus replaces one of the adjacent special symbols while the rest are removed or disappear.
