Abstract: 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.

Abstract translation: 公开了用于产生散列值的方法，系统和计算机程序。 基于输入数据获得无前缀值。 无前缀的值可以基于隐式证书，要签名的消息，要验证的消息或其他合适的信息。 通过将哈希函数应用于无前缀的值来获得哈希值。 哈希值用于加密方案。 在某些情况下，基于哈希值生成公钥或私钥。 在某些情况下，根据哈希值生成数字签名，或者根据哈希值，适当地验证数字签名。
