摘要： Methods, systems, and computer programs for using an implicit certificate are disclosed. In some aspects, a message and an implicit certificate are accessed. The implicit certificate is associated with an entity. A modified message is generated by combining the message with a value based on the implicit certificate. A digital signature can be generated based on the modified message and transmitted to a recipient. In some aspects, a digital signature from an entity and a message to be verified based on the digital signature are accessed. An implicit certificate associated with the entity is accessed. A modified message is generated by combining the message with a value based on the implicit certificate. The message is verified based on the digital signature and the modified message.

摘要： Methods, systems, and computer programs for using an implicit certificate are described. In some aspects, an implicit certificate is accessed. The implicit certificate is associated with an entity and generated by a certificate authority. The implicit certificate includes a public key reconstruction value of the entity. Certificate authority public key information is accessed. The certificate authority public key information is associated with the certificate authority that issued the implicit certificate. A first value is generated based on evaluating a hash function. The hash function is evaluated based on the certificate authority public key information and the public key reconstruction value of the entity. A public key value of the entity can be generated or otherwise used based on the first value.

摘要： Methods, systems, and computer programs for producing hash values are disclosed. A prefix-free value is obtained based on input data. The prefix-free value can be based on an implicit certificate, a message to be signed, a message to be verified, or other suitable information. A hash value is obtained by applying a hash function to the prefix-free value. The hash value is used in a cryptographic scheme. In some instances, a public key or a private key is generated based on the hash value. In some instances, a digital signature is generated based on the hash value, or a digital signature is verified based on the hash value, as appropriate.

摘要： Methods, systems, and computer programs for producing hash values are disclosed. A first hash value is obtained by applying a first hash function to a first input. The first input can be based on an implicit certificate, a message to be signed, a message to be verified, or other suitable information. A second hash value is obtained by applying a second hash function to a second input. The second input is based on the first hash value. The second hash value is used in a cryptographic scheme. In some instances, a public key or a private key is generated based on the second hash value. In some instances, a digital signature is generated based on the second hash value, or a digital signature is verified based on the second hash value, as appropriate.
