Reino: Security Features

Segurança de software não é o mesmo que software de segurança. Aqui, estamos interessados em tópicos como autenticação, controle de acesso, confidencialidade, criptografia e gestão de privilégios.

Key Management: Empty HMAC Key

Abstract
Chaves HMAC vazias podem comprometer a segurança do sistema de uma maneira difícil de remediar.
Explanation
Nunca é uma boa ideia usar uma chave HMAC vazia. A força criptográfica do HMAC depende do tamanho da chave secreta, que é usada para o cálculo e a verificação dos valores de autenticação de mensagens. Usar uma chave vazia enfraquece a força criptográfica da função HMAC.
Exemplo 1: O seguinte código usa uma chave vazia para calcular o HMAC:

...
DATA: lo_hmac TYPE Ref To cl_abap_hmac,
Input_string type string.

CALL METHOD cl_abap_hmac=>get_instance
EXPORTING
if_algorithm = 'SHA3'
if_key = space
RECEIVING
ro_object = lo_hmac.

" update HMAC with input
lo_hmac->update( if_data = input_string ).

" finalise hmac
lo_digest->final( ).

...


O código mostrado no Example 1 pode ser executado com êxito, mas qualquer usuário que tiver acesso a ele será capaz de descobrir que ele utiliza uma chave HMAC vazia. Depois que o programa é distribuído, provavelmente não há forma de alterar a chave HMAC vazia, a não ser que um patch seja aplicado ao programa. Um funcionário desonesto com acesso a essas informações poderia usá-las para comprometer a função HMAC. Além disso, o código no Example 1 é vulnerável a ataques de falsificação e recuperação de chave.

Abstract
Chaves HMAC vazias podem comprometer a segurança do sistema de uma maneira difícil de remediar.
Explanation
Nunca é uma boa ideia usar uma chave HMAC vazia. A força criptográfica do HMAC depende do tamanho da chave secreta, que é usada para o cálculo e a verificação dos valores de autenticação de mensagens. Usar uma chave vazia enfraquece a força criptográfica da função HMAC.
Exemplo 1: O código a seguir usa uma chave HMAC vazia para gerar o hash HMAC:

...
let hmacKey = "";
let hmac = crypto.createHmac("SHA256", hmacKey);
hmac.update(data);
...


O código no Exemplo 1 pode ser executado com êxito, mas qualquer usuário com acesso a ele poderá descobrir que ele utiliza uma chave HMAC vazia. Depois que o programa é distribuído, provavelmente não há forma de alterar a chave HMAC vazia, a não ser que um patch seja aplicado ao programa. Um funcionário desonesto com acesso a essas informações poderia usá-las para comprometer a função HMAC.

Abstract
Chaves HMAC vazias podem comprometer a segurança do sistema de uma maneira difícil de remediar.
Explanation
Nunca é uma boa ideia usar uma chave HMAC vazia. A força criptográfica do HMAC depende do tamanho da chave secreta, que é usada para o cálculo e a verificação dos valores de autenticação de mensagens. Usar uma chave vazia enfraquece a força criptográfica da função HMAC.

Exemplo 1: O seguinte código usa uma chave vazia para calcular o HMAC:

...
digest = OpenSSL::HMAC.digest('sha256', '', data)
...


O código no Example 1 pode ser executado com êxito, mas qualquer usuário que tiver acesso a ele será capaz de descobrir que ele utiliza uma chave HMAC vazia. Depois que o programa é distribuído, provavelmente não há forma de alterar a chave HMAC vazia, a não ser que um patch seja aplicado ao programa. Um funcionário desonesto com acesso a essas informações poderia usá-las para comprometer a função HMAC. Além disso, o código no Example 1 é vulnerável a ataques de falsificação e recuperação de chave.
