名前: Cryptographic Operations are Run Before Supporting Units are Ready
Performing cryptographic operations without ensuring that the supporting inputs are ready to supply valid data may compromise the cryptographic result.
一般情報
背景の詳細
導入モード
Architecture and DesignImplementation : The decision to continue using a cryptographic unit even though the input units to it are not producing valid data will compromise the encrypted result.

潜在的な緩和策
Phases : Architecture and DesignBest practices should be used to design cryptographic systems. If a cryptographic unit retrieves a private encryption key from a fuse unit, the fuse unit must be up and running before a key may be supplied.
Phases : Implementation
Continuously ensuring that cryptographic inputs are supplying valid information is necessary to ensure that the encrypted output is secure.
脆弱性マッピングノート
理由 : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.コメント : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

| CAPEC-97 | Cryptanalysis
Cryptanalysis is a process of finding weaknesses in cryptographic algorithms and using these weaknesses to decipher the ciphertext without knowing the secret key (instance deduction). Sometimes the weakness is not in the cryptographic algorithm itself, but rather in how it is applied that makes cryptanalysis successful. An attacker may have other goals as well, such as: Total Break (finding the secret key), Global Deduction (finding a functionally equivalent algorithm for encryption and decryption that does not require knowledge of the secret key), Information Deduction (gaining some information about plaintexts or ciphertexts that was not previously known) and Distinguishing Algorithm (the attacker has the ability to distinguish the output of the encryption (ciphertext) from a random permutation of bits). |
