Key-Uniformity Sample Clauses
The Key-Uniformity clause ensures that all cryptographic keys used within a system or agreement are generated and distributed in a manner that guarantees uniform randomness and unpredictability. In practice, this means that keys must be created using secure, standardized random number generators and must not exhibit any patterns or biases that could be exploited by attackers. This clause is essential for maintaining the integrity and security of encrypted communications, as it prevents vulnerabilities arising from weak or predictable key generation.
Key-Uniformity. In the remainder of this work we will require a technical condition on E˜, which informally assures that E˜ does not behave structurally different for different keys. For instance, it should not be the case that for some keys, l1 can take only one value independent of the tweak, while for other keys, it can take 2n values (one for every tweak). We will call this property “key-uniformity.” Note that the condition slightly limits the generality of the scheme, but it is quite reasonable that a scheme should behave comparably for all keys. For brevity, view the functions Bpre for i = 1,...,ρ as mappings (ka, kb, t) '→ lpre, and the functions B for i =1 as mappings (ka, kb, t) '→ l . Note that, indeed, (ypre,..., ypre), is a function of (ka, kb, t) for any i.
