Abstract: Systems and methods are described for rotating keys in a trust store to be used by a group of peer devices for secure communications between the peers in the group. In some examples, a service, such as an identify authority service, may make a determination that a set of peers that individually trust at least one public key from a group of public keys satisfies a set of conditions. As a result of the determination, the service may update the plurality of public keys by at least removing at least one public key from the group of public keys and indicate the updated plurality of public keys to at least one of the peers in the group. The service may remove the at least one public key from the group upon determining that less than a threshold number of peers in the group use the at least one public key.

Abstract: A system performs cryptographic operations utilizing information usable to verify validity of plaintext. To prevent providing information about a plaintext by providing the information usable to verify the validity of the plaintext, the system provides the information usable to verify validity of the plaintext to an entity on a condition that the entity is authorized to access the plaintext. The information usable to verify validity of the plaintext may be persisted in ciphertext along with the plaintext to enable the plaintext to be verified when decrypted.

Abstract: A first public key is generated based at least in part on a first plurality of signing keys and a second public key is generated based at least in part on a second plurality of signing keys. The signing keys may be used to generate digital signatures. The second public key may be made available to verify a digital signature generated using a signing key from the second plurality of signing keys. In some cases, a first Merkle tree may be formed by the first public key and the first plurality of signing keys, and a second Merkle tree may be formed by the second public key, the first public key, and the second plurality of signing keys.

Abstract: A computing resource service receives a request. In response to the request, the computing resource service queries a probabilistic data structure for an entry corresponding to the request. The computing resource service obtains, from the probabilistic data structure, a value that corresponds to the entry. Based at least in part on this value, the computing resource service determines whether the entry has expired. If the entry is expired, the request is fulfilled. However, if the entry has not expired, the request is denied.
