Abstract
Techniques are provided for securing reference signals. An example method for transmitting a signal based on a validated pseudo random sequence includes determining secure sequence validation information, generating a pseudo random sequence, validating the pseudo random sequence based on the secure sequence information, and transmitting the signal based at least in part on the validated pseudo random sequence.

A method for transmitting a signal based at least in part on a validated pseudo random sequence, comprising:
- determining secure sequence validation information;
- generating a pseudo random sequence, wherein a counter value, a plain text value, or a combination thereof, is utilized by a cryptographic algorithm configured to generate pseudo random sequences;
- validating the pseudo random sequence based at least in part on the secure sequence validation information;
- and
- wirelessly transmitting the signal based at least in part on the validated pseudo random sequence.
A method for receiving a signal based at least in part on a validated pseudo random sequence, comprising:
- determining secure sequence validation information;
- generating a pseudo random sequence, wherein a counter value, a plain text value, or a combination thereof, is utilized by a cryptographic algorithm configured to generate pseudo random sequences;
- validating the pseudo random sequence based at least in part on the secure sequence validation information;
- and
- wirelessly receiving the signal based at least in part on the validated pseudo random sequence.
An apparatus, comprising:
- a memory;
- at least one transceiver;
