摘要： An electronic device for generating a masking signal is described. The electronic device includes a plurality of microphones and a speaker. The electronic device also includes a processor and executable instructions stored in memory that is in electronic communication with the processor. The electronic device obtains a plurality of audio signals from the plurality of microphones. The electronic device also obtains an ambience signal based on the plurality of audio signals. The electronic device further determines an ambience feature based on the ambience signal. Additionally, the electronic device obtains a voice signal based on the plurality of audio signals. The electronic device also determines a voice feature based on the voice signal. The electronic device additionally generates a masking signal based on the voice feature and the ambience feature. The electronic device further outputs the masking signal using the speaker.

摘要： A Management System (MS) manages signing privileges for entities desiring cryptographic signatures, and a Certificate Authority (CA) provides a cryptographic signing service. MS registers entities for the cryptographic signing service, determines signing privileges for each entity, and processes requests from entities for signatures. For registration, MS obtains registration information for the entity and invokes CA to generate an identity certificate for the entity. This identity certificate contains cryptographic information used to uniquely identify the entity. For signature generation, MS receives a request for a signature from the entity, authenticates the entity, authorizes or denies the request based on the signing privileges stored for the entity, and invokes CA to generate the signature if the signature is authorized. CA provides the cryptographic signing service and generates signatures and certificates as directed by MS.
摘要翻译：管理系统（MS）管理希望加密签名的实体的签名特权，证书颁发机构（CA）提供加密签名服务。 MS为加密签名服务注册实体，确定每个实体的签名特权，并处理来自实体签名的请求。对于注册，MS获取实体的注册信息，并调用CA为该实体生成身份证书。该身份证书包含用于唯一标识实体的加密信息。对于签名生成，MS从实体接收到签名请求，根据为该实体存储的签名特权来认证实体，授权或拒绝请求，并且如果签名被授权，则调用CA生成签名。 CA提供加密签名服务，并按照MS的指示生成签名和证书。
