Abstract: The present disclosure relates to systems and methods for secure communications. In some aspects, an initiator KMS receives, from an initiator UE, one or more values used in generation of an encryption key, which includes obtaining at least one value associated with a RANDRi. The initiator KMS sends the at least one value associated with the RANDRi to a responder KMS. The responder KMS generates the encryption key using the one or more values.

Abstract: A computer-implemented authenticated encryption method for converting a plaintext message into a ciphertext message. The method includes dividing the plaintext message into at least two working blocks, each working block having a mathematical relationship to the plaintext message. For each working block, a working block ciphertext is computed as a function of such working block, a deterministic working block initialization vector, and a deterministic working block encryption key. For each working block, a message authentication tag is computed as a function of a deterministic working block message authentication key and at least one of (a) the working block ciphertext computed for such working block and an indication corresponding to the mathematical relationship of such working block to the plaintext message and (b) such working block. The method further includes computing a global message authentication tag as a function of the message authentication tag computed for each working block and a global message authentication key. The ciphertext message comprises the working block ciphertext computed for each working block and the global message authentication tag.

Abstract: 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.

Abstract: A framework is proposed for authenticated encryption for digital signatures with message recovery whereby authentication is achieved without a redundancy requirement. The finite cyclic group signature scheme is modified through the use of authenticated encryption, thereby enabling authentication using a message authentication code (1028). The authenticated encryption may be performed within a single function or as two separate functions. The authenticated encryption may also be applied to associated data in the message (104) to be signed.
Abstract translation: 提出了一种用于具有消息恢复的数字签名的认证加密的框架，从而在没有冗余要求的情况下实现认证。 通过使用认证加密来修改有限循环组签名方案，从而使得能够使用消息认证码（1028）进行认证。 认证加密可以在单个功能中或作为两个单独的功能执行。 认证加密也可以应用于要签名的消息（104）中的相关联的数据。

Abstract: 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.
